Motor no responding to teensy command

[YiKangOY]

Hello!
We have configure teensy and odrive by your code(The only difference is we use AS5047P with a cpr of 4000, which I assume won't impact main function. We also comment out //#define USE_XBEE so we are using computer serial.)

However, when we send command (ie. E, R)to teensy by Serial software on computer, the motor was not moving at all, it just stay in close_loop state.

In the function SendByte, a "uint8_t" byte(which equals to unsigned char) is transformed into a "char", I guess this leads to my problem because when byte>=128 it will be transform to a negative number but I have not idea if this really matters.
void ODriveArduino::SendByte(uint8_t byte) { serial_ << (char)byte; }
Thanks!

Hey @lotharelvin,

Just wanted to see if you resolved this issue or not. We are running into this issue as well, but we believe that we have a work around to get open loop control working without any feedback for the theta and gamma values.

We will post an update here with the potential work around later today, but in the meantime if you can get back to us with your experience that would be helpful!

Cheers
