// 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().
