基于寄存器操作的STM32高级定时器TIM1的四路PWM输出程序讲解
基于寄存器操作的STM32高级定时器TIM1的四路PWM输出程序讲解经过一天的努力，终于把stm32tim1的四路pwm输出搞了出来，为了使大家快速的用起tim1，打算写这篇文档与大家分享。
Stm32tim1功能丰富。
由于PWM输出和TIM2之间只有很小的差别，我在网上找到了一些网友的程序，发现大多数程序都是基于库文件编写的，所以我无法深入了解TIM1的PWM 输出。
我认为一个想要充分利用芯片的合格程序员应该直接对寄存器进行操作，并充分了解计时器的操作过程，你可以对电影的结构有一定的了解。
高级控制定时器(tim1和tim8)由一个16位的自动装载计数器组成，它由一个可编程的预分频器驱动。
它适合多种用途，包含测量输入信号的脉冲宽度(输入捕获)，或者产生输出波形(输出比较、pwm、嵌入死区时间的互补pwm等)。
使用定时器预分频器和rcc时钟控制预分频器，可以实现脉冲宽度和波形周期从几个微秒到几个毫秒的调节。
高级控制定时器（TIM1和tim8）和通用定时器（timx）是完全独立的，它们不共享任何资源。
请读者仔细阅读一下信息：脉冲宽度调制模式可由timx生成。
ARR寄存器确定频率，该频率由timx确定。
ccrx寄存器确定占空比信号。
在timx中，ccmrx寄存器中的ocxm位被写入“110”（PWM模式1）或“111”（PWM模式2），这可以独立设置每个OCX输出通道以生成一个PWM。
必须设置timx。
ccmrx寄存器的ocxpe位启用相应的预加载寄存器。
最后，应设置timx。
CR1寄存器的ARPE位（在递增计数或中心对称模式下）使预加载的寄存器能够自动重新加载。
只有在发生更新事件时，预加载寄存器才能传输到卷影寄存器，因此必须在计数器开始计算EGR寄存器中的μg位之前设置timx，以初始化所有寄存器。
可通过软件在timx中检测OCX的极性。
CCER寄存器中的ccxp位已设置，可设置为高级有效或低级有效。
【三菱案例】高速脉冲输出——多位移动案例
【三菱案例】高速脉冲输出——多位移动案例高速脉冲输出——多位移动案例程序截图内容分析开机初始化程序使用开机脉冲信号，传送不同的数值，且进行浮点数运算求出一个脉冲所走的长度。
1.使用【MOV】指令传送K20（周长）、K400（一圈的脉冲数）到D2、D4；2.使用【FLT】整数转浮点数指令，把周长和脉冲转换成浮点数（小数）；3.使用【DEDIV】浮点数除法运算，用周长（D6）除以一圈的脉冲数（D8），得出一个脉冲所走的长度（D10）；4.使用【MOV】传送指令，把变址寄存器V0清零。
不同点位长度设置使用【M3】辅助继电器控制参数写入，主要是写入不同长度，有多少个长度就写入几条指令，本截图7个长度，所以有七条指令。
注意：此程序是配合触摸屏使用，D50到D62的数值由触摸屏输入。
1.使用【FLT】整数转浮点数指令，把通过触摸屏输入的数值（D50到D62）转换成浮点数存放在（D100到D112中）；2.使用【DEDIV】浮点数除法指令，把设定的长度除以一个脉冲走的长度，得出设定长度所需的脉冲数；3.使用【INT】浮点数转整数指令，把求得的每段长度所需的脉冲数转换成整数，以供发脉冲指令使用；发脉冲指令执行部分使用【M0】辅助继电器【SET】置位【M1】，把启动信号保持住，在使用【M1】常开触点驱动【PLSY】高速脉冲输出指令，把【D200V0】的脉冲数以800HZ的频率通过【Y0】口发送出去，其中【D200V0】使用了变址，这样就只需要编辑一条发脉冲指令。
1.【M8029】脉冲结束标志位，脉冲发送完了之后，接通一个扫描周期。
即：【D200V0】找寻到的地址内的脉冲数发送完成后接通一瞬间。
2.使用【M8029】复位【M1】停止驱动发脉冲指令，再置位【M2】作为停止信号；3.使用【M2】的常开触点，接通一个定时器，做停止时间，停止1秒；同时使用【ADDP】加法指令，改变变址寄存器【V0】的数值（此段为可以看为加2计数），且复位【M2】；再使用定时器【T0】的上升沿重启激活【PLSY】发脉冲指令；4.使用触点比较指令，当【D200V0】的数值为零时，就停止所有启动信号，使其不能输出；已走长度部分1.使用【M8000】开机一直接通辅助继电器，驱动【DMOV】32位传送指令，把【D8140】Y0发出的脉冲总数传送给【D0】；2.使用【FLT】整数转浮点数指令，把总脉冲数转为浮点数存入【D20】；3.使用【DEMUL】浮点数乘法运算，把【D20】总输出脉冲数乘上【D10】一个脉冲所走的长度，结果存放在【D22】中，即：D22等于当前总长度。

Morningstar 四通道逻辑控制器应用指南说明书
Relay Driver Applications GuideMorningstar’s Relay Driver (RD) is a fully programmable 4-channel logic controller that can be used to control mechanical or solid-state relays in an AC or DC power system. A limitless number of combinations can be configured for each channel on the RD to control the switching of circuits on and off based on several variables present in the system. The purpose of this document is to explore three of the many applications and uses of this product:Hybrid System ControlLighting ControlMulti-Wire Generator StartMorningstar’s MSView software is used to configure the Relay Driver and its settings will be explained in each system scenario. Please visit to learn more about the flexibility of the RD.Hybrid System Control –Alarm Signals and Generator ControlIn this application, the Relay Driver is used to send voltage alarms to a communications device provided by the user at the site. It also will monitor battery voltage and start a generator whenever there is insufficient solar charging from the PV array.The first channel controls the generator. In this particular application, the generator has its own internal warm-up and starting controls. Therefore only a single circuit is needed for the sequence to begin. The generator control mode can be used, but only one wire (the “run” signal) needs to be set up since the generator’s own controls take care of the rest of the start sequence. Two relay channel outputs (channels 2 and 3) are used to signal high and low voltage alarms on the battery bank. This alerts the user of the system (through a spare input on the communications link of their equipment) thatthe battery is higher or lower than the normal operating range due to a fault of some type.Finally, channel number 4 signals if there is a fault with the TriStar controller itself. This may indicate a higher level hardware failure regarding the TriStar’s operation that could not be detected with simple voltage readings. Each of the final channel setups are shown in Fig. 1Fig. 1 Hybrid ConfigurationThe first 3 channels are just threshold settings allowing the relay to be switched on when a certain voltage is met and turned off when that level returns to the normal range. Fig. 2 shows this set up for the gen start (channel 1). The gen start mode allows a delay time to be set for start up and shut down to prevent wear and tear on the generator engine from cycling too frequently.Fig. 2 Voltage Threshold Setup for GenstartThere are several alarms and faults that the TriStar is able to detect using its on-board diagnostics. Any combination of these can be monitored and linked to the Relay Driver so that relays can be opened or closed upon their detection. Fig. 3 shows a list of available faults and alarms. The user simply checks the ones to be monitored by the RD.Fig. 3 TriStar Alarm and Fault SelectionLighting Control – Primary and Secondary Lighting ConfigurationFig. 4 below shows a TriStar with Relay Driver being used in a lighting application for a large off-grid bus stop. The primary load has a ballast that requires a significant surge at startup. For this reason, a mechanical relay provides the most robust way to turn the circuits on and off. This same set up could even be used for applications where a small inverter could power AC lighting loads.Fig. 4 Lighting controlThere are 2 circuits being used. The high-power ballast-controlled lights are connected to the primary circuit, and some smaller low power LED lights are connected to a secondary circuit.The relay driver serves 2 purposes:1. Monitor voltage of the PV array (in conjunction with the TriStar) to activate the lights at night automatically and turn them off in the morning.2. Shut off the primary lights (which draw most of the energy) and activate the low power LED lights during periods of bad weather and low battery state-of-charge.By observing PV voltage (that the TriStar is communicating to the RD via the RJ11 cable) the Relay Driver is able to see when night occurs and will turn the lights on and off accordingly.As can be seen by the wiring, individual lighting circuits can be controlled independently, or all lights can be turned on and off together. Fig. 5 below shows how the PV will turn off all the lights according to night (<8V on the PV panel) and day (>10V on the PV panel). The two lights are tiered so that as battery level gets dangerously low, only low powered LED lighting is used to conserve energy. If the battery gets to a very low level (10.8V) then the LED’s will also be turned off to prevent battery damage.Fig. 5 Lighting Control ThresholdsMulti-Wire Generator StartIn this application there is a generator and battery but no photovoltaic system, and thus no TriStar charge controller in use. The Relay Driver is used in stand alone mode to control the function of a more sophisticated generator start sequence.The first set up is the generator start and stop. In stand alone mode, the Relay Driver accomplishes this with battery voltage readings (taken at its own power terminals) as shown in Fig 6.Fig. 6 Battery ThresholdsIf a generator does not offer its own control for more sophisticated timing, the different channels of the relay driver can be configured to switch each of the control wires required to run a generator. Since this is a diesel generator, a pre-heat function is needed to warm the glow plug briefly before attempting to turn on the engine (accomplished by channel 1). The second phase of starting requires that the run and ignition signals are activated at the same time (channels 2 & 3). Crank Delay is the amount of time that takes place after Pre-Crank but before the engine turns on. Fig. 7 shows a close-up of the starting cycle that the RD will go through once the low battery voltage level is reached.Fig. 7 Generator Starting CycleA maximum run time can be set in the case of a complication in which the batteries are not fully charged. These time limits are shown in Fig. 8.Fig. 8 Max./Min. Run TimesConclusionIn addition to the above examples, many other types of logic are possible. Up to 750mA of current can be drawn on each channel, meaning multiple relays can run off each channel output. Also, relays may be wired in such a way that only combinations of conditions on multiple channels would activate a relay. This gives the user Boolean logic control over the system if desired.Three of many possible scenarios that utilize the Morningstar Relay Driver were discussed in this document. Others include:-Diversion control for wind or hydro systems.-Temperature based control using the RD’s internal temp sensor or the TriStar’s optional Remote Temperature Sensor placed at the battery bank.-Pump control using battery based, direct PV or generator based systems with float control switches monitored by the Relay Driver.To learn more about the Relay Driver’s options, please download MSView from the Morningstar company website at The RD setup wizard in MSView may be explored freely without the RD hardware.。

编程技巧问答：
提问：FX2N无法在梯形图编辑软件里输入DRVI指令，怎么办？
回答1：可以通过整行复制/粘贴在FX1N梯形图编辑软件里的DRVI指令到现在的FX2N 梯形图编辑软件里来解决。
回答2：改变PLC类型的方法：
1，由FX2N改到FX1N，这样就可以直接使用DRVI指令了。
改变D8101的值为26300，重新上电PLC就改变为FX1N。
2，由FX1N改到FX2N
改变D8101的值为24300，重新上电PLC就改变为FX2N。
