Reset needed between two UART transmission

[FCam1]

Hi,
On my Odrive 3.4 it appears the motors stop turning if I follow this steps: Sending commands, stopping sending, restarting sending. The ODrive stops after the first sending, I have to reset the board .
The board is not complitely freezed because if I try to send over USB it works. It seems that is only the UART entry that freeze.

I send commands from a microcontroller at 100Hz.

Someone else saw this effect ? Did someone have an idea about the cause ?

Hi,

may be you have the same issue as me. Try this:

ASCII commands makes ODrive unreachable

Hi all, I try to connect the output of a simulator software to ODrive. My setting is a 3.5 board with the latest devel branch. Connected is a KEDA motor with mounted AMT102. The startup sequence is running fine and the motor resposes to the commands through a serial connection. Everything looks good till this point. This is the UI of the simulator software: [grafik] As you can see, the software sends a initial positioning command, waits for 1 second and starts to send positions every 50ms…

Hi,

It also looks like the same issue as me :

UART Communication: Maximum frequency ? Timeout?

Hi Guys ! I am trying to communicate with my ODrive via UART with a Raspberry pi. I basically copied the Arduino code that is proposed by @madcowswe here. I mostly use the setcurrent function as explained in the ascii protocol and I also wish to get the encoder position. I am meeting a timeout issue (from the readString() function) : I can send the current command at a quite frequency (1kHz) to ODrive and everything works perfectly fine. If I want to get the encoder position (sending the req…
