Hello, My name is Mahmoud form Turkey,
I'm trying to connect Delta Hmi with modbus protocol using RS485 connection method. I use STM32F103C8 microcontroller. I'm trying to apply to finish my internship project, I know that I cant directly connect MCU with HMI using modbus so I get MAX485 chip.
I have found some library but I can't figure it out.
any body can help please?
I still fresh on stm32 topics
