uint8_t RxHandler

(

uint8_t

c

)

Handles the incoming bytes from the interface selected in QDebugSettings.h and puts the bytes in the RX_Buffer data read by the selected interface.

Returns

uint8_t: returns a true if more data must be read, returns a false if the frame is complete

Note

Used by SPI and TWI receive handlers.
