With respect to UART functionality, what is the difference between _io_read() & _io_scanf() functions OR _io_write() & _io_printf() functions?
Is _io_read() a blocking call?
Basically I would say io_read and io_write are used to read/write a single character, where io_scanf and io_printf are used for formatted output/input.
It would help to know which processor you are targeting for a more accurate answer.
The processor used is M52259. I would like to know which among them are blocking calls.
All of them are blocking calls.
