Using mesa uart for modbus RTU? was created by thang
Does mesa_uart use 10 bits frame include:
1 bit start + 1 bit stop+ 7bit data+ 1 bit parity
Or it is 11 bits frame include:
1 bit start + 1 bit stop+ 8bit data+ 1 bit parity
I 'm trying to use it to read data from a drive that using RTU modbus, but not sure it is possible?

The Hostmot2 UART is 8 bits 1 start 1 stop no parity
The latest firmware supports Parity on the PktUART but only 8bit+ parity
The PktUART is more suitable for Modbus RTU since it has built in
packet idle framing for TX and RX
