Estoy enviando datos desde la UART de arduino. los pines Ra2 se supone que debe hacerlo y parpadea cuando entra en la interrupción. Los datos de Dennis se muestran correctamente. Pero los datos recibidos por el PIC no se devuelven correctamente y estoy obteniendo basura en la salida del puerto serie.
