Hi I trying to implement PPP using LWIP over new keil 5.1 so on manage run time environment it force me to select uart_driver from cmsis rtos drivers but there is no access to uart_writedata and read data those implemented static in UART_STM32F10x.c and interrupt is also implemented on UART_STM32F10x.c so is anyone can help me to fix this to write my own standard modem file to start LWIP The problem is how to access uart using RTE drivers
any Idea?!
