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 … WebAug 1, 2024 · Hello.

WebCompared to the USART interrupt method, the DMA interrupt method achieves lower DE signal switching times. So, if DMA is available for data transmission, it is preferable to use it. The two methods meet the RS-485 & IO-link timing requirement of 230 kbs transfer speed (bit time = 4.34 µs). WebAug 13, 2015 · Modbus is a protocol that runs on top of a serial connection. It defines messages and their content. RS-232 and RS-485 (and sometimes "TTL", for 0.8V/2.0+V levels) are physical implementations of a serial connection. They define voltage levels for "high" and "low", and how devices are connected together. darbs patio eaton rapids michigan
