STM32 inbuilt function

[Swastik_Dey]

Hey everyone, just like there is a function named "Serial.available()" in Arduino,is there any such function present in STM32 ?

Hi,

No.

btw   " in STM32" -> this is cpu series , so library functions cannot be there.

If you want the Arduino environment with STM32 cpu , you could use Arduino_Core_STM32 boards lib.

Most STM32 have a single byte depth buffer in the UARTs. To read that check the RXNE bit.

To make larger buffers you can query you should make a fifo/ring buffer you fill via interrupts.
