WebJul 24, 2024 · RS-485, also known as TIA-485 (-A), EIA-485, is a standard defining the electrical characteristics of drivers and receivers for use in serial communications systems. You are going to have to figure out what protocol you want to use with your RS-485 port to write your program. You can also see if the manufacturer of the temp controller has ... WebWhen you configure a USART for the STM32G484 in CubeMX, it gives you a choice of RS485 or Modbus (but not both!). Yet, Modbus RTU runs *on top of* RS485, so this makes no sense. The Modbus configuration appears to put the MCU USART into half-duplex mode. I have seen RS485 implementations that use RTS with an external driver to switch from …
