HiI want to implement Modbus slave RTU/ASCII protocol on STM32F103VET6. I have read many forums about Modbus and examined several libraries, but unfortunately I couldn’t do it and I’m disappointed. In this blog: https://blog.naver.com/eziya76/2209703...

Ok, I'll check it. My discovery board has a RS485 module (SP3485 IC). I want to use this instead of serial port. This IC has two states, driver enable and reciever enable. When should I enable driver mode and when I should enable reciever mode?Thank...

Thank you.Yes, at first I guessed so, but in the blog, he used usb serial for modbus protocol. I don't know how that works.So, if I run the library and use a RS485 IC like SP3485 (in the pdf above) will this work?
