I'm trying to drive tmc2209 on stm32, the problem on the code is all done. But I encountered some strange problems, I hope to get help from developers。
The thing is this, when I use the stm32 to send the read command directly to the tmc2209, it does not have any feedback message。But when I use the usb on the pc to transfer to ttl, I can read the corresponding return message by sending the same command. Even when I try to connect the usb to ttl and the uart port of stm32 to the uart port of tmc2209. And send instructions on the pc. At this time, tmc2209 does not return the message。
The whole thing is so weird so hoping for some help from you guys
