【AT-START-F425 Review】USB to CAN final chapter: Communicating with the car ECU [Copy link]

 

 

All the previous experiments are just to lay the foundation, and they will eventually be used in the project:

This test was done with a car ECU exported to Iran. This was left over from the CAN test project I did with him using STM32F103VE.

The initial connection of its communication protocol is:

Expression	Enable	Testing Method	Corresponding agreement	Remark
OK/NG	1	The host computer sends the corresponding CAN protocol code to see if it can read the required data normally.	id：01f10208 data[7]	0 is normal		SENDEXT0500000 01f10208 3 00 00 00

Our development board did not receive any information after restarting:

After we send the command, we can receive the data sent by CAN:

This shows that the connection between F425 and CAN is successful.

[Summary] After several days of debugging, the project is finally finished. It also achieved the effect of my preview. It can be said that the F425 chip is far more powerful than the stm32F103 series chips in terms of CAN and USB functions. It is a very good choice in today's chip shortage.

Additional effects:

In terms of CAN and USB functions, it is completely possible to replace stm32F103

It looks good. Does the command support CAN data frame sending?

It's all OK, it's standard CAN communication protocol.

Can I apply for a sample trial?

Or link a purchasing address

If you have any needs, I have applied for samples to see if I can get the chips. If I can, I will post here.

It looks pretty good!

The replacement of stm32 is just around the corner.

Hobby, want to play with the entire CAN device and automotive electronics

It's very simple, you just need to get a development board. If you want, wait until my trial is over. If you really want it, I'll give you my board.

Okay, I hope you finish it soon.

Also, do you have any recommendations for development boards?

The N32G45 I used before is also OK. In fact, they are all similar. It mainly depends on the price.
