Currently I am using the FRDM-K64F board with kds and KSDK and I need to use a serial port.
I can transmit and receive data, but when I want to control, I can't find the necessary functions:
1- I need to know how many bytes were received at a reception in the data block (UART_DRV_ReceiveData function) and
2- I need to know how many bytes are available in the receive buffer before reading data block from the reception buffer.
Thanks in advance
