UART Interface

The ODrive's UART0 interface is enabled by default with a baudrate of 115200 on the pins as shown in Pinout.

To use UART connect it like this:

• Tx of the ODrive <=> Rx of other device
• Rx of the ODrive <=> Tx of other device
• GND of the ODrive (use any GND pin on J3 of the ODrive) <=> GND of the other device

The logic level of the ODrive is 3.3V. The GPIOs are 5V tolerant.

You can use odrv0.config.uart0_baudrate to change the baudrate and odrv0.config.enable_uart0 to disable/reenable UART0. Currently the UART port runs both the Native Protocol and the ASCII Protocol at the same time.
