Further tests and development can be carried out shortly after Riverdi STM32 Evaluation Board is switched on for the first time.OverviewThe Riverdi evaluation board is designed as a complete demonstration and development platform for Riverdi’s EVE and IPS displays lines driver technology.The Riverdi evaluation board features an STM32F469II Cortex-M4 microcontroller with: LCD parallel interface including 8080/6800 modes, an LCD-TFT controller, Chrom-ART Accelerator™ for enhanced graphic content creation (DMA2D), secure digital input/output interface (SDIO), LTDC signals available on header P11 with additional MCU pins broken out on P12, external SDRAM, MicroSD slot for data/media storage, RiBUS FFC conn P3 featuring SPI, UART and LCD supply pins (SPI can be controlled by either STM32 or UBS serial bridge via jumper on P7/8/9) and configurable display backlight supply (EXT/INT).IntroductionRiverdi STM32 Evaluation Board is a tool designed to help get you started on working with Riverdi products. It not only supports EVE modules but also RGB displays (in combination with touch panels) by Riverdi.You have two primary options to drive external displays:1.Jumper between P7 & P8: FTDI serial/SPI bridge connected to RiBUS SPI:Use the FT232 serial to SPI bridge by connecting a micro USB cable to the connector labeled “Direct USB” and using the EVE Screen Editor to quickly generate graphical user interfaces with minimum effort .2.Jumper between P9 & P8: STM32 connected to RiBUS SPI:Use the onboard STM32F4 to develop and test firmware for driving a connected display or display controller, like the FT80x, FT81x and BT81x series.Board functionality testThere are firmware examples with which you can test your Riverdi STM32 Evaluation Board. You can also use those as a starting point for your own firmware development.Interfacing with EVE DisplaysUsing the FTDI SPI Bridge & EVE Screen EditorPrerequisites:•Riverdi STM32 Evaluation Board•EVE-enabled display•RiBUS flexible flat cable (FFC)EVE Screen Editor InstallationDownload and install the EVE screen Editor from the FTDI homepage:https:///Support/Utilities.htm#EVEScreenEditorSetup & ConfigurationTo connect the FTDI SPI bridge to the EVE display, the configuration jumpers need to be placed between P7 and P8, as in the picture below.Set the backlight jumper (placed over the backlight power configuration pins) to 5V BL on P4 (also refer to the picture below). Please see description on how to connect power for backlight in section “Hardware features”, subsection “Backlight power supply”.Start EVE Screen Editor and you will be greeted with the screen similar to the one below:On the lower right hand side of the window, click on the ”Devices” tab.On the lower left hand side, you will find 3 buttons:This button refreshes the devices list above it;This button opens a menu to select one from the preconfigured displays list;This button opens a menu to define your own display to be driven.Use a USB cable to connect the “USB Direct” port to your computer, when running the EVE Screen E ditor application. Click the “Refresh” button afterwards and your dev board should show up like in the picture below:Select "Single RS232-HS ()” entry by clicking on it and use the ‘Connect’ button to let EVE Screen Editor try and boot up your display.If everything works properly, your display should show a blue screen with some text.Hello WorldAfter connecting to Eval Board, to generate its first text message (e. g. 'Hello World'), we are going to use the EVE Screen Editor’s built-in drag & drop editor.(The drag operation is shown in green, the generated coprocessor commands are shown in the yellow box and the button to send the data to the EVE display is seen inside the red box.)What you see now is the preview of what will be drawn on the physical screen in a moment. Note that in the lower part of the window the coprocessor tab shows which EVE pre-processor commands were generated and will be sent to the EVE display shortly after.To send the commands also drawn in the preview pan to the physical display, press the button labeled “Upload RAM_G and RAM_DL”.Using the SPI on the STM32Prerequisites•Riverdi STM32 Evaluation Board•EVE enabled display•RiBUS flexible flat cable (FFC)•Your favorite tool to flash the onboard STM32 (assuming that you use STM32CubeProgrammer together with an STLink v2 compatible ISP Programmer)InstallationUse the provided source code or the pre-compiled binary file.ConfigurationIn order to connect the STM32 to the EVE display, the configuration jumpers need to be placed between P9 and P8. Check the jumper and the USB cable position (in ‘STM32 USB’ socket) in the picture below.Hardware featuresModule power supplyPossible to deliver from one of 2 USB ports on Eval Board (“Direct USB” or “STM32 USB”), in accordance with USB standard (5.0 VDC max.)Backlight power supply7.2.1InternalFor display sizes from 3.5” to 5.0”, the USB port gives enough power to get adequate backlight level. Such backlight power supply configuration (jumper is in higher position, connects BL to 5V on P4) is shown in the picture below.For 7.0” displays, USB minimal power capability needs to be 700mA @ 5V (this is a combined power of Eval Board, BT817Q board and backlight). Please make sure your USB source has enough current efficiency. If not, use external 5V power source in the way described in point 6.2.2.7.2.2ExternalAll the 10.1” (and rarely certain 7.0” displays) require external power supply for backlight, as the backlight voltage exceeds 5V and power consumption is over the USB standard. To provide adequate backlight power, set the jumper in P4 to lower position (it connects BL to EXT) – it must be placed in lower position and connect the external DC voltage source to neighboring connector (“BL PWR”). Refer to the picture and below.Caution! There is no reverse polarity protection on EXT_BL_PWR, incorrect connection will damage the backlight permanently.

STM32 LL 库使用指南说明书
STM32 LL库使用指南---By Fengzi熟悉STM32的都知道ST官方提供了非常方便好用的库函数供用户使用，多数人都使用过STM32标准外设库，STM32Cube库(即HAL库)，这个LL库是什么鬼，却从来没听说过。
好吧，我承认这个名字是我自己XJB取的。
目录一、初识LL 库 (1)二、怎么使用LL库 (3)三、新建STM32LL库工程模板 (5)四、第一个程序——点亮LED (8)五、添加其他程序功能 (10)………………………………………………………………………………………………………………………………………………….一、初识LL 库最近论坛发的STM32L476RG Nucleo开发板到手了，准备学习玩耍，当然第一步就是下载资料，于是我下载STM32L4Cube 1.1.0版本，打开逐个查看，好像和以前一样的，没什么特别嘛，于是准备开始开发。
等等，好像还真发现了有点不一样：熟悉HAL库的都知道，该库的文件几乎都是以stm32xxx_hal_xxx.h/.c命名的，为了和以前的标准库有个区分，上图中那些是什么鬼前辈说，遇到问题赶紧查手册，于是我果断打开STM32L4Cube库的说明手册(UM1884):原来这个东西叫做Low Layer APIs，作为英文渣渣表示实在不习惯洋里洋气的高大上名字，于是擅自把他叫做【STM32LL库】了(不服的你咬我啊）。
从这里看好像是说这个东东比HAL库更接近硬件，到底什么鬼，还不清楚。
但是以前好像没见过这个东西啊，就算是STM32L4Cube的1.0.0版本中都没有。
看看Cube发行历史：原来LL库是在1.1.0版本才加上的，大概意思就是：1.LL APIs是寄存器级的编程，嗯，也就是说我们常说的直接操作寄存器吧。
2.LL APIs适用于xxx等一大堆外设3.LL APIs函数全部定义为static inline函数，放在对应的头文件中，用户使用需要包含相关头文件4.参考这两个文档看看LL库文件在Cube库中的位置，有20多个文件，全部以stm32l4xx_ll_xxx.h命名：STM32Cube_FW_L4_V1.1.0\Drivers\STM32L4xx_HAL_Driver\IncSTM32L4是面向低功耗市场的，同时不失高性能，功耗和性能往往是两个矛盾的东西，ST在硬件设计上想了各种办法来实现兼顾低功耗高性能(例如各种低功耗模式，LP外设等)，而在软件层面，程序也讲求效率，LL库全是直接操作寄存器，直接操作寄存器往往效率较高，而且函数定义为内联函数，调用函数时不是堆栈调用，而是直接把函数的代码嵌入到调用的地方，利于提高代码相率，我想这也是ST在STM32L4系列中推出这个直接操作寄存器的LL库的原因之一吧。

Before using this interface, you should install a CP2102 driverfirstly.Run the installer: .\Xnucleo \tools\CP2102 driver\PreInstaller.exeWhen the installation finished, connect the XNucleo board to a PC via the USB TO UART interface.And you will find the CP210x USB to UART Bridge Controller in the Device Manager, if the driver is installed successfully.Run the installer: .\Xnucleo user\tools\STM32 ST-LINK Utility\STM32 ST-LINK Utility_v3.4.0.exe (For more detailed information about installation and usage of STM32 ST-LINK Utility, pleaserefer to the document provided by ST: .\Xnucleo user\tools\STM32 ST-LINKUtility\Readme\STLINK Utility.PDF. You can also download the latest installer from the STwebsite).When the installation finished, connect the ST-LINK/V2(mini) module to a PC. You will find the STMicroelectronics STLink dongle in the Device Manager, if the driver is installed successfully.Run the installer:.\Xnucleo user\tools\JLinkARM\Setup_JLinkARM_V415e.exeWhen the installation finished, connect the J-Link emulator to a PC. You will find the J-Link driver in the Device Manager, if the driver is installed successfully.1.2.GETTING STARTEDPlease follow the sequence below to configure the STM32 Xnucleo board and launch the demo software:561) Jumper settings ● Set JP3 to U5V; ● Set JP2 to ON;2) Power supply and power selection●For using a USB power supply, connect the Xnucleo board to a PC with a USB cable through the onboard USB connector; ●For using an external power supply, connect the power supply socket CN2 on the Xnucleo board to a 6~12V power adapter. 3) Connect the ST-LINK/V2 (mini) debugger/programmer to the SWD connectorNotices: It is recommended to plug in the USB power supply or the external power supply before connecting the ST-LINK/V2(mini) module to the SWD interface. Otherwise, the ST-LINK/V2(mini) initialization may be failure.The blinking of the USER LED indicator will change from fast to slow or from slow to fast, when clicking the USER key.2.2.1POWER SUPPLY SETTINGSThe power supply of the STM32 Xnucleo board is provided either by the host PC through the USB cable, or by an external source:●VIN (7V~12V) or +3V3 power pins on CN6;●E5V(5V) pin on CN7;●CN2 power supply connector (7V~12V).In case VIN, E5V, +3V3 or CN2 is used to power the Xnucleo board, you should use an external power supply unit.All parts of the STM32 Xnucleo board and Shield can be powered from the ST-LINK/V2 (mini) USB connector by the host PC.In case the ST-LINK/V2 (mini) USB connector is used to power the Xnucleo board, the host PC will provide 150mA current at maximum as 3.3V voltage is outputted from the ST-LINK/V2 (mini) USB connector to the Xnucleo board. And 300mA current at maximum may be provided when 5V voltage is outputted to the Xnucleo board. In case of the board requiring the current more than 300mA, it should be mandatory to use an external power supply as explained in the next chapter.Each part of STM32 Xnucleo including the extension board can be powered by USB(U5V).However, if the maximum current consumption of the board exceeds 300mA, the USB may be damaged. When the board is power supplied by USB(U5V), a jumper must be connectedbetween pin 1 and pin 2 of JP5 as shown in Table 2.Table 2: Power-related jumper7U5V (ST-LINK VBUS) is used as power source when JP5 is set as shown below (Defaultsetting)CN2, VIN or E5V is used as power source when JP5 is set as shown belowCN2, VIN or E5V can be used as external power supply in case the current consumption of Xnucleo and its extension boards exceeds the allowed current on USB. In this condition, it is mandatory to power supply the board using the external power source firstly, then connect the USB cable and ST-LINK/V2 (mini) to the PC to ensure that the Xnucleo board can work properly.Table 3: External power source parametersNotices: The following power sequence procedure must be respected when using an external power source:1)Set JP3 to U5V;2)Connect the external power source to CN2, VIN or E5V;3)Power on the external power supply CN2, VIN: 7V~12V, or E5V: 5V;4)Check that PWR LED is turned ON;5)Connect the PC to USB connector or ST-LINK/V2(mini) on Xnucleo.89If this order is not respected, the board may be supplied by VBUS or ST-LINK/V2(mini) firstly, and the following risks may be encountered:If more than 300 mA current is needed by the board, the PC may be damaged or the current supply can be limited by the PC. As a consequence the board cannot work correctly.●When powered by CN2, VIN or E5V, the +5V (CN6 pin 5 or CN7 pin 18) can be used as output power supply for an Arduino shield or an extension board. In this case, the maximum current of the power source specified in Table 3 needs to be respected. ●The +3.3 V (CN6 pin 4 or CN7 pin 12 & 16) can be used also as power supply output. The current is limited by the maximum current capability of the regulator U4 (500 mA max).2.2LED INDICATORSThe LEDs on the STM32 Xnucleo board is used to provide information about the Xnucleo working status.Table 4: The relationship between LED and the pins of MCUIt is easy to use each LED by setting JP7. For XNUCLEO-F302R8, the pin PB13 is connected to the MCU pin D13. And for other XNUCLEO devices, the pin PA5 is connected to the MCU pin D13. When the I/O is HIGH value, the FLASH LED is on. And when the I/O is LOW, the FLASH LED is off.10The PWR LED default color is red. It indicates the power supply status of the STM32 Xnucleo board. The red LED indicates that the MCU part is powered by +5V.TX indicator is in green, and RX indicator in blue. The blinking TX indicator means the MCU of STM32 Xnucleo board is sending message to the targeted PC. The blinking RX indicator means the MCU of STM32 Xnucleo board is receiving message from the targeted PC.2.3PUSH BUTTON The USER button is connected to the I/O PC13(pin 2) of the targeted MCU by setting JP6 to ON;This RESET button is connected to NRST, and is used to reset the targeted MCU.2.4JP2 (IDD) JUMPER SETTINGS STM32 microcontroller is powered (default).When this jumper is removed, STM32 microcontroller is not powered. But you can connect an ammeter on the JP6 to measure the STM32 microcontroller current.2.5USART COMMUNICATIONThe USART2 interface available on PA2 and PA3 of the STM32 microcontroller can be connected to Virtual COM Port, STMicroelectronics Morpho connector or to Arduino connector.Please set the JP4 as follows, to connect the targeted MCU to serial port (For more information, please refer to Table 6 and Table 7).●Connect the RX/PA3 of JP4 to the TXD;●Connect the TX/PA2 of JP4 to the RXD.If the communication between the targeted MCU and shield or extension board is required, you should set the JP4 and the RX/D0 and TX/D1 on CN9 as follow (For more information, please refer to Table 6).●Connect the RX/PA3 of JP4 to the RX/D0;●Connect the TX/PA3 of JP4 to the TX/D1.In such case it possible to connect another USART (if another USART is available on the targeted MCU) to the targeted MCU through Virtual COM Port using flying wires as follow●Connect the TX/PC10/PC6 of JP4 to RXD;●Connect the RX/PC11/PC of JP4 to TXD.Here is the jumper setting for connecting to XNUCLEO-F030R8:●Connect the TX/PA9 of JP4 to RXD;●Connect the RX/PA10 of JP4 to TXD.Notices: You should select a proper USART by referring to Table 5 and make corresponding hardware configurations, according to your actual demand. The USARTs (USART1 and USART3) listed in this table are unavailable under mbed, since only USART2(PA2, PA3) is defined for mbed. Therefore, when the USART-related APIs (such as printf) are required under mbed, you should select USART2(PA2, PA3) to connect to Virtual COM Port or CN9 on the pins RX/D0 and TX/D1.Table 5: USART-related pins and jumpers1112Table 6: Connections of JP4 pinsTable 7: Connections of NUCLEO-F030R8 JP42.6ADC OR I2C COMMUNICATIONIf ADC or I2C communication is required, you can connect the ADC interface or the I2C interface to the Arduino connector or the ST Morpho connector by setting the JP5. Here are the relative settings to JP5:●The pins A4 and A5 of JP5 should be connected to the Arduino connector on the pins A4 and A5 (the pin 5 and the pin 6 of CN8) or the ST Morpho connector on the pins 36 and 38 of CN7 respectively; ● The pins SDA/PB9 and SCL/PB8 of JP5 corresponding to the I2C interface of STM32 MCU; ●The pins PC1/ADC and PC0/ADC of JP5 corresponding to the ADC interface of STM32 MCU.Table 8: Connections of JP5 pins2.7 SPI CONNECTORThe pins D11, D12 and D13 of Arduino connector are SPI interfaces. For XNUCLEO-F302R8, the pins PB13, PB14 and PB15 are connected to the pins D13, D12 and D11, respectively. And for other XNUCLEO devices, the pins PA5, PA6 and PA7 are connected to the pins D13, D12, and D11, respectively.2.8USB CONNECTORExcept the XNUCLEO-F030R8, all the other XNUCLEO devices have reserved a USB connectorwhich can be enabled by setting JP1 to ON.2.9SOLDER BRIDGESTable 9: solder bridgesNotes: All the other solder bridges present on the STM32 Xnucleo board are used to configure several IOs and power supply pins for compatibility of features and leads with STM32 MCU supported.2.10EXTENSION CONNECTORThe following figures show the signals connected by default to Arduino connectors (CN5, CN6, CN8, CN9) and to ST Morpho connector (CN7 and CN10), for each STM32 Xnucleo board.13Figure 1: XNUCLEO-F030R8Figure 2: XNUCLEO-F103RBFigure 3: XNUCLEO-F302RC14Figure 4: XNUCLEO-F401REFigure 5: XNUCLEO-F411RE153.Xnucleo series is fully compatible with Nucleo series and can run the Nucleo Demos directly.Therefore, you can develop your STM32 Xnucleo applications based on the applications ofSTM32 Nucleo. Table 10 gives the relationship between Xnucleo series and Nucleo series.Table 10: Relationships between Xnucleo series and Nucleo seriesThe operations presented in this document are based on XNUCLEO-F103RB. For differentXnucleo devices, there may be some differences in configuring the development environment.So users should operate according to the actual conditions.3.1HOW TO COMPILE AND DOWNLOAD PROGRAM UNDER MBEDIn this section, we only present the ways to compile and download program, since it does not have room to address every factor of mbed. For more detailed information about the usage of mbed, please refer to the documents provided by mbed organization.Here we take XNUCLEO-F103RB as an example. Start the mbed software, and open a program,no error, Compile Output will show “Success!” after the compiling is finished. And the fileNucleo_printf_NUCLEO_F103RB.bin will be generated.

It provides an affordable and easy-to-use solution for driving high power bipolar stepper motors in your STM32 Nucleo project. The fully digital motion control through speed profile generation, dynamic positioning feedback and a complete suite of protection features offer high levels of performance and robustness The X-NUCLEO-IHM03A1 is compatible with the Arduino UNO R3connector and supports the addition of other boards which can be stacked to drive up to three stepper motors with a single STM32 Nucleo board.Figure 1: X-NUCLEO-IHM03A1 expansion board for STM32 NucleoContents UM1910 Contents1Getting started (3)2Hardware description and configuration (4)2.1Selecting the chip select and clock lines of the SPI (6)2.2Multi-motor configuration (6)3Revision history (11)UM1910Getting started1 Getting startedThe X-NUCLEO-IHM03A1 expansion board is a high power stepper motor driver covering a wide range of applications. In particular, the maximum ratings of the board are the following. ∙ Power stage supply voltage (VS) from 10.5 V to 50 V ∙ Motor phase current up to 10 A r.m.s.Follow this sequence to start your project with the board:1. Check the jumper position based on your configuration (see Section 2: "Hardware description and configuration").2. Plug the board to the STM32 Nucleo board through Arduino UNO R3 for the X-NUCLEO-IHM03A1.3. Supply the board through the input 1 (VS) and 2 (ground) of the connector CN1. The power OK (green) and fault (red) LEDs will turn on.4.Develop your application using the examples provided with the firmware library, X-CUBE-SPN3, high power stepper motor driver software expansion for STM32Cube. Further support material is available on the powerSTEP01 (/powerstep) and STM32 Nucleo web pages (/stm32nucleo).Up to three expansion boards can be stacked on the same STM32 Nucleo board as described in Section 2.2: "Multi-motor configuration".2 Hardware description and configurationFigure 2: "Jumper and connector positions" shows the position of the connectors and theconfiguration jumpers of the board.Figure 2: Jumper and connector positionsBelow are the pinout details for the Arduino UNO R3 and the ST Morpho connectors.Notes:(1)All the unlisted pins are not connected.Notes:(1)All the unlisted pins are not connected.2.1 Selecting the chip select and clock lines of the SPIThe chip select and the clock lines of the SPI interface can be selected via the appropriateresistors indicated in Table 3: "Chip select line selection" and Table 4: "Clock lineselection".2.2 Multi-motor configurationThe expansion boards can be stacked on a single STM32 Nucleo board in order to drive upto the three stepper motors (one expansion board for each motor is required).The configuration is changed by mounting the resistors from R3 to R8 as listed in Table 5:"Multi-motor setup table".The other resistors are not mounted.By default, the stepper driver board is configured for a single-motor setup, so the boardconfiguration must be changed in multi-motor setups before stacking the boards on theSTM32 Nucleo.UM1910 Revision history 3 Revision historyUM1910IMPORTANT NOTICE – PLEASE READ CAREFULLYSTMicroelectronics NV and its subsidiaries (“ST”) reserve the right to make changes, corrections, enhancements, modifications, and improvements to ST products and/or to this document at any time without notice.

STM32nucleo_L476RG使用指南
为了使用以前的 printf 函数，首先需要引入库函个新的 fputc 函数 //Retargets the C library printf function to the UART. int fputc(int ch, FILE *f) {
HAL_UART_Transmit(&huart2, (uint8_t *)&ch, 1, 0xFFFF); return ch; } 这样就可以兼容以前开发的 F103 的功能函数了。 注意：如果系统中需要多个串口，需要对 printf 进行二次封装，自己开发 USRAT_printf 函数，其原理是，每次在使 用 printf 函数前，先变换此函数的对应的输出设备的句柄，例如换成串口 1，串口 2。 利用 printf 函数输出串口数据，效率一般。
digitalHi(GPIOA,GPIO_PIN_5)
#define LED3_ON
digitalLo(GPIOA,GPIO_PIN_5)
四、串口函数的使用
1.发送函数
HAL_UART_Transmit(&huart2,"HELLO\n",30,3); 其中，第一个参数比较变态 UART_HandleTypeDef huart2; UART_HandleTypeDef 为系统定义的一个结构体。
