I’m currently trying to use UART to communicate from a Raspberry Pi B3+ to a 24V Odrive, but am getting an error (shown below), when I run this simply python script:
[FIBRE] transport layer "serial" not implemented
import odrive import serial def main(): print("Connection to Odrive...") o = odrive.find_any("serial:/dev/ttyAMA0") ...
I understand that odrivetool had their UART implementation removed, but I was wondering if it was removed for running regular python script in the native protocol.
- I double checked that the connections from the Raspberry Pi B3+ to the Odrive were correct:
- Gnd <-> Gnd
- Tx of Odrive (GPIO1) <-> Rx of Raspberry Pi (Pin 10)
- Rx of Odrive (GPIO2) <-> Tx of Raspberry Pi (Pin 8)
- This is how I configured the ODrive via USB before removing the connection for UART:
odrv0.config.enable_uart_a = True odrv0.config.gpio1_mode = GPIO_MODE_UART_A odrv0.config.gpio2_mode = GPIO_MODE_UART_A odrv0.config.uart0_protocol = STREAM_PROTOCOL_TYPE_FIBRE odrv0.reboot()
- I ensured that the UART wiring was enabled on the Raspberry Pi B3+ before attempting to use UART on the Odrive
I understand that odrivetool isnt set up to use UART currently, but does this affect regular python scripts too? (Odrivetool with UART does not seem to work - githubhot)
I was wondering if anybody had any other reccomendations on things we could try to get this to work?
