there is a board that use stm32f0 that sending data via rs485 and i have a board that use lpc1768 that use adm485 as rs485 ic
every 400 ms stm board send me a few byte information and i see it in oscope but in lpc1768 i keep getting this error ARM_USART_EVENT_RX_OVERFLOW
why is that?
can ADM485 5v output to MCU be cause of problem?
what do u think?
