Hi3516开发学习心得

Hi3516开发学习心得

Hi3516开发学习心得Hi3516开发学习心得1.开发环境1.1>概述嵌入式系统通常是一个资源受限的系统,因此直接在嵌入式系统的硬件平台上编写软件比较困难,有时候甚至是不可能的。

目前的解决方法是采用宿主机、目标机的开发模式。

在宿主机上编写程序,通过交叉编译器生成目标板上可以执行的二进制代码。

然后通过文件系统,将二进制代码放在特定目录下,在目标板上运行。

宿主机:VMWARE \\ ubuntu(服务器:192.168.1.101)环境:交叉开发工具包,nfs目标机:linux hi35161.2>安装过程参见卖方附赠视频教程“SDK安装及编译视频.avi”。

nfs文件系统挂载:挂载点改变修改/etc/exports文件,具体方法自行谷歌。

2.开发流程首先要有这样一个意识,即对开发板进行的配置,是以我们的需求为基础的。

我们所做的工作在系统层次图的应用层部分:所需的函数统一由MPP(媒体处理平台)提供接口。

MPP封装实现了基本功能函数,屏蔽掉了对底层的操作。

sample_venc.c为完成视频采集编码一系列操作的代码。

观察其代码风格如下:1.函数返回值作为状态码,用以判断函数是否执行成功。

2.函数需要传出的值通过全局变量或地址传出。

现在以函数先后顺序(也即视频采集编码处理流程)对各步骤做以说明。

2.1配置视频缓存池:视频缓存池作用:视频缓存池主要向媒体业务提供大块物理内存管理功能,负责内存的分配和回收,充分发挥内存缓存池的作用,让物理内存资源在各个媒体处理模块中合理使用。

由于视频输入通道不提供创建和销毁公共视频缓存池功能,因此,在系统初始化之前,必须为视频输入通道配置公共视频缓存池。

根据业务的不同,公共缓存池的数量、缓存块的大小和数量会有所不同。

enPayLoad---------------决定编码格式。

enSize--------------------决定图像分辨率。

(利用不同的编码通道,可以对同一rowdata编码出不同的分辨率。

基于Hi3516A的高清视频处理系统的硬件设计

基于Hi3516A的高清视频处理系统的硬件设计

基于Hi3516A的高清视频处理系统的硬件设计作者:孙刚刘守山樊丽来源:《科技风》2017年第16期摘要:提出了基于Hi3516A的高清视频处理系统的硬件设计方案。

利用IMX185图像传感器采集图像,经过系统的编解码,然后通过HDMI接口传输到显示器上。

主要介绍了电源管理模块的设计、存储器模块的设计、JTAG接口的设计、HDMI接口的设计等。

关键词:Hi3516A;高清视频;视频处理系统视频处理系统在近年来一直受到人们广泛关注,然而低分辨率的图像已经满足不了人们对图像视觉的要求。

本视频系统采用Hi3516A芯片作为核心,可以实现1080p的高清视频采集和传输。

本文主要介绍了一套高清视频的采集与传输系统的硬件设计,可以应用到医疗,交通和监控等众多领域。

1 系统总体设计系统采用的Hi3516A是基于Cortex-A7内核,主频最高可以达到600Mhz,还具有32KB 的指令缓存和数据缓存和128KB的二级缓存,其内部集成了H.264/H.265/MJPEG/JPEG的多协议编解码器,既支持1080p@30fps,而且支持SM@30fps等的多码流实时独立编码;视频输入接口支持BT.601,BT.656,BT.1120;支持HDMI接口的高清视频传输。

本系统采用CMOS 传感器获得图像数据,通过Hi3516A芯片实现对视频的实时采集与传输。

最终在PC端等地实现高清播放。

系统的设计总框图如图1所示。

2 硬件的各模块设计2.1 图像传感器模块本系统采用的是索尼200万像素的IMX185的CMOS传感器,具有高灵敏度和多功能输出接口(低压LVDS并行,串行和CSI-2系列)的特点,支持光学尺寸1/2型全高清,具有高达120帧/秒的10位A / D转换模式,以及高达60帧/ s的12位A / D转换模式。

3516C (HD) 整机端口说明

E L E C T R O N I C S6.0 ElectronicsThis section of the 3516C HD Well Fracturing Project Guide highlights content to cover the most common questions on Electronics. For a complete in-depth guide on 3516C HD Well Fracturing Electronics, refer to SISWeb publication REHS2998.6.1 J1939 DatalinkRefer to SISWeb document REHS2998 for details on wiring specifications and guidelines for the J1939 CAN datalink. 6.1.1 Broadcast-Only ParametersThe following Table 18 shows the list of parameters the 3516C HD Well Fracturing engine ECM broadcasts (send-only) on the J1939 CAN Datalink.E L E C T R O N I CSE L E C T R O N I C S6.1.2 Torque Speed Control 1 (TSC1) The original SAE design for the TSC1 message was for truck applications as a temporary means for the transmission to override engine speed during gear shifts. More advanced system integration has evolved the use of the TSC1 message for use as a permanent means of controlling engine speed by off engine control systems.E L E C T R O N I C SThis is a powerful feature, but special care must be taken by the OEM with the implementation of TSC1 to ensure that the speed demanded of the engine is one that is safe and appropriate for the current operating conditions of the engine. It is the responsibility of the OEM to ensure this is so and to perform the necessary risk assessment and validation of the software for the electronic modules transmitting TSC1 speed demand messages to the engine or transmission.Table 19 reflects the operation of the Torque Speed Control 1 (TSC1) J1939 parameter group for 3516C HD Well Fracturing engines.E L E C T R O N I C S6.1.3 TFAC (PGN 61466 / SPN 3464)SAE J1939-71 “Engine Throttle / Fuel Actuator Control Command”, TFAC for short, is an engine speed demand method available for the 3516C HD Well Fracturing engine.Per the SAE standard, this signal is normalized to an operational percentage range of 0% to 100%. For 3516C HD Well Fracturing engines, this signal is interpreted to request an engine speed where 0% requests Low Idle, and 100% requests High Idle.6.2 Speed Control Interfacing for Electronic Transmissions3516C HD Well Fracturing engines can utilize PWM and TSC1 for customer engine speed requests. TFAC is also available, but PWM or TSC1 are preferred methods over TFAC.• When using PWM or TFAC, the PWM signal is sent directly to the engine on customer connector pin 10 or TFAC is sent to the engine via J1939. The transmission, whether manufactured by Caterpillar or another, may then send speed/torque limiting signals to the engine via the J1939 CANE L E C T R O N I C Sdatalink. Refer to Electronics A&I Guide REHS2998 in SISWeb for further details on PWM signal requirements.• When using TSC1 throttle, it is necessary to verify with the transmission manufacturer the transmission requirements and capabilities to avoid arbitration issues with the engine. The engine ECM cannot accept and correctly arbitrate TSC1 requests from multiple sources (e.g. bothcustomer controller and transmission). Ideally, the transmission should be able to accept a J1939 speed request from the customer controller(whether TSC1 or another PGN) and then send the engine the appropriate arbitrated speed or speed/torque limit requests. • When using a Cat transmission, the recommended speed demand method is via a proprietary J1939 speed signal (referred to as Prop A) to the transmission ECM. After receiving the Prop A speed demand signal from the customer controller, the transmission then sends the engine theappropriate arbitrated speed request over the J1939 datalink based upon current operating conditions in relation to the operator’s demanded speed, gear, and transmission protection requirements. Details on the Prop A signal can be seen in the following Tables 21 and 22.E L E C T R O N I C SAn example Prop A data field is shown in Table 22. This example is requesting 800 rpm engine speed.6.3 Throttle Input ConfigurationThe desired type of throttle input signal to control engine speed must be configured properly. If not configured, a 91-8 diagnostic code indicating an abnormal throttle position sensor signal may be generated if only J1939 throttle control is used. To properly configure this parameter, select the appropriate speed demand method from the “Speed Control” configuration group in Cat ET.6.4 Customer ConnectorThe pinouts for the engine customer 40-pin connection can be found in Table 24 below. For a complete system wiring diagram, refer to the engine wiring diagram in SISWeb, UENR2650.E L E C T R O N I CSE L E C T R O N I C S6.5 Electronics Cold Weather ConsiderationsAll electronic components (ECM, wiring, and sensors) for 3516C HD WellFracturing engines are rated for operation down to -40°C (-40°F). Operation in air temperatures colder than this will require further assessment and design considerations by the OEM. CAUTION: Allowing water to freeze on or around engine components canpotentially cause damage. This is a consideration in any ambient temperature below the freezing point of water.6.6 Monitoring and Protection SystemThe monitoring system determines the level of action that is taken by the ECM in response to conditions which could damage the engine. When any of theseE L E C T R O N I C Sconditions occur, the appropriate event code will be generated. Refer to SISWeb Troubleshooting guide and the OMM for further information and cross-references for Event and Diagnostic codes generated by the ECM.Table 25 contains the conditions that are monitored and the default trip points for each condition for the 3516C HD engines. Each condition has an associated parameter. The settings for each parameter can be viewed with Cat Electronic Technician (Cat ET). The trip points for some of the parameters may be adjustable with Cat ET.3516C HD PETROLEUM WELL FRACTURING PROJECT GUIDE©2013 Caterpillar All rights reserved.54E L E C T R O N I C SELECTRONICS ©2013 Caterpillar All rights reserved. 55。

一、 概述
基本工作原理
HA3516 采用矩阵扫描方式实现更多触摸按键的解决方案采用定时充放电差值法,利用固定时间对转 换模块电路进行充放电,根据后端电平变化差值,获取有/无按键的状态。
固定频率和占空比的信号 PWM 通过电容耦合进入转换电路,经二极管反向续流后会形成带直流分 量的脉动信号,简单滤波后输入到芯片内部进行检测。 当无按键时,该脉动直流电平是由稳定的电容的充放电、续流和滤波电路保持稳定。当有按键时候, 放电续流部分不会被改变,但充电部分受到手指加入的影响,相当于充电回路 RC 增大,在相同的 时间内,得到电压会比没有手指时候低。所以,在手指接触感应电极的时候,该点的直流电位下降 了。通过该直流电位的变化情况,分析是否有手指按键。 同一按键检测口上在外围硬件上连接了两个不同的感应按键,当 PWM1 和 PWM2(Pulse drive)快 速地分时切换,分别对两组按键进行检测。通过上述方式实现了 2x8 的矩阵扫描。 当手(人体)非常靠近或接触按键感应焊盘(或弹簧)时候,由按键检测电路提供给芯片的电压会 发生改变,体现为该电压下降。具体过程如下图所示(以下数据是在 5v VDD 供电,5mm 玻璃覆盖 厚度情况下测得):
