I work on RS485 communication between dk-s124 by adding SN65176B and raspberrypi with RS485 shield https://www.reichelt.com/de/en/Development-Board-Accessories/RPI-RS485/3/index.html?ACTION=3&GROUPID=8244&ARTICLE=162304
I tried to communicate a frame of bytes using UART and it works. But, after adding the RS485 transceiver I receive just the first byte.
