// Program: NMEA_isr.ino
//
// Prerequisites:
// 1) NMEA.ino works with your device
//
// Description: This minimal program parses the GPS data during the
// RX character interrupt. The ISR passes the character to
// the GPS object for parsing. The GPS object will add gps_fix
// structures to a buffer that can be later read() by loop().
