Re: MCC UART receive string
Receiving a string is nothing more than receiving multiple single characters - one after the other.
I wouldn't bet on MCC configuring some "receive string" function as the buffer (size) required heavily depends on what you want to receive.
Why not receive your string by receiving individual characters, stuffing them into some buffer until you recognize (by some way) the end of the string ?
