i'm using mesa_uart to read serial data but i have a issue. Sometimes, after sending 8 bytes, the phase A isnt come back idle state-5V state (it keeps 0V state). This mean uart is still getting data after first 8 bytes,then the UART data shows me rx-bytes = 16, all rx-data = 0.
Is mesa_uart posible to limit the number bytes UART read? 2018-03-16 23:52 GMT+07:00 Peter C.
