Hello, ST company. I bought your development board steval-idp004v1 and steval-idp003v1 about IO-Link. But I have a problem.

The downloaded program does not follow the instructions in the documentation (STEVAL-IDP004V1's green light flashes, STEVAL-IDP003V1's green light flashes). The result is that STEVAL-IDP004V1 has no lights flashing and STEVAL-IDP003V1 has a red light. I used the USB connection development board and entered the programmatic actions in the documentation that still responded, but could not INSERT REGISTER VALUE: this step. My downloaded programs are all from

I sincerely hope that you can help me to solve the trouble I have encountered. I need your technical support, and I will be very grateful. I hope you can provide me with:

1.

Can normally operate in accordance with the documentation of the project procedures source code(Program download address), and it is better to use "Keil5" to develop the engineering files (because I bought this software, and many projects are developed with this software).

2. About the simplified version of the IO-Link communication protocol, I only need to use the IO-Link device and STM32 for simple data transmission effect, and tell me in the code in an obvious and easy to understand way.

Thank you again and look forward to your reply.

ST公司您好，我购买了你们关于IO-Link的开发板STEVAL-IDP004V1，STEVAL



-IDP003V1。但是我遇到了问题。
下载的程序并没有按照说明文档中的正常运行（STEVAL-IDP004V1的绿灯闪烁，STEVAL-IDP003V1的绿灯亮）。下载完后的现象是STEVAL-IDP004V1没有灯闪烁，STEVAL-IDP003V1红灯亮。我使用USB连接开发板，输入说明文档中的编程操作仍然有反应，但是无法通过 INSERT REGISTER VALUE: 这一步。我的下载的程序均来自于

我迫切希望你们能够帮助我解决我遇到的麻烦，我需要你们向我提供技术支持，我会非常感激。我希望能够提供给我：
1.能够正常按照文档中进行操作的工程程序源代码(程序下载地址)，并且最好是使用Keil5开发的工程文件（因为我购买了这款软件，并且很多项目均是使用这款软件进行开发的）
2.关于IO-Link通讯协议的简化版，我只需要使用IO-Link设备和STM32进行简单数据传输的效果，并且用显而易见容易理解的方式在代码中告诉我。
再一次表示感谢，期待得到你们的回复。

从产品型号上看，你所说的这个评估板上的主器件与通用处理器是两个部门的产品。至少官方的产品线是这么分的。 所以   IO-Link Transceivers  这个评估板软件是该器件部门的产品，建议联系他们提供或者联系销售代理商帮助申请。 如果有路过的大神谁有相关资源还请帮忙提供一下
