Modbus (over RS485)

Post by Docara »

Hi
Does the Modbus component invoke a COM Port interrupt when data is received on a MCU's hardware COM port? (or even a pin change interrupt via a GPIO pin if a software COM port is used)

Thanks

Hi Docara,

The Modbus component running on a microcontroller uses the corresponding UART RXinterrupt to collect incoming comms data, therefore software channels are not enabled for the component.
