An existing project runs on STM32F091, it use CMSIS USART driver (Async mode, ARM_DRIVER_USART Driver_USART1). Now I need to migrate this project to run on STM32G070. But for STM32G070, there aren't any USART driver under CMSIS driver (in keil's "manage run time environment"), except a header file for customary implementation. So what is the best way to migrate UART functionality? Do I need to implement a similar CMSIS USART driver for G0 series? (CMSIS should be easier for migration, now it seems to cause more trouble.)

Hey, you found my initial post on ST forum where I learn the CMSIS driver is implemented by keil, not ST; the problem is not solved, that's why I post it here looking for solution.
So, when it is solved, remember to mark the solution on both threads.
