bonjour.
nouveau sur ce forum je cherche de l aide pour mon GPS skylab skm53  connecte sur les pin RX 50, TX 51 de ma carte arduino mega 2560(seul les pin 10, 11, 12, 13, 50, 51, 52, 53, 62, 63, 64, 65, 66, 67, 68, 69 peuvent etre utilise en RX).  mon problème: ss.available() revois toujours 0 alors que  ss.read() renvois des chaine.

RX GPS connecte au TX arduino.
TX GPS connecte au RX arduino.
VCC GPS -> 5V arduino.
GND GPS ->GND arduino.

librairie utilisee: TinyGPS 12
