Can the RA4M1 UART control the RE/DE signal for a RS485 line driver in equipment, or does FSP control it in software?
Hello, Primary your STLINK is China clone, RST pin is for STM8 not STM32, for correct under reset require hw alter inside. Unconnect RST from prog and test Ordinary mode connect. Secondary when you load code into MCU, that set SWD pins to utilize or any low power stop mode , this block connection inRead more

Hello, The FSP UART module has RS-485 Half Duplex driver support with outside RS-485 transceiver. FSP handles the DE pin for RS-485. It just needs to be configured on FSP UART module: Thank You
