1.UART Serial available function ? 2.Serial Flush Function ? 3. Serial Printf Function ?

[PPati.18]

Working On STM32 Nucleo-L476RG board.

STM32Cubemx and Atollic Truestudio Im using for code development.

I have following questions Related to UART and HAL Functions...!

1.UART Serial available function ?

• we have any function like arduino have serial.available() function to know serial have data or not. finding HAL functions.

2.Serial Flush Function ?

• we have any function like arduino have serial.flush() function to erase all data from serial buffer. finding HAL functions.

3. Serial Printf Function ?

• we have any function like arduino have serial.print() function to print all type of data on serial like char, string , int values. finding HAL functions.

Please Help me out. i just started STM32 programming.

any example code or link

No, no and no. And that's good, because Arduino API is at schoolboy level. HAL USART API is described in file stm32l4xx_hal_usart.c and internet is full of examples:
