Hey. I am working with STM32 microcontroller and I need to design a modbus communications using RS485 interface. The microcontroller will need to communicate to another device using modbus which I havent got details about.
I have found few relevant chips (LTC485 and LTC1480) that provide RS485 capabilities. Considering that the STM32 microcontroller that I am using operates on 3.3V logic, I would use LTC1480. I have found few examples of wiring the LTC485 but I am struggling to find some helpful example circuitries for LTC1480. I assume LTC485 would be very simmilar, is that a good example to look at? What would be PD5 pin going into __RE?
