Hi All. I want to turn on leds on a grid receiving from serial a number (for the position of the led) and a letter to call a hex code. I mean, to make faster the serial communication I want to send just a letter to call for example¨: unsigned long s = 0x006600; Green unsigned long f = 0x0000…

Parsing data integer plus letter

I would use

switch( strtokIndx[0] )

like @guix already mentioned and explained.
