I used Arduino_Core_STM32 V1.9.0. Recently I updated the version of “ Arduino_Core_STM32 ” from V1.9.0 to V2.7.1 . Ardunio ide tip： ArduinoModbus and ArduinoRS485 not compatible with STM32. I compile the old project and then use jlink to flash .bin file to stm32F103C8T6. The RS485 communication couldn't work any more. How can I solve this problem?
