I've got this code from DFRobot wiki page that we had running on a Mega. Captures GPS data one-time and sends a text.
Am adapting it for a 1284 board I have to capture & send every two minutes. Simple blink-without-delay addition, easy, yes? However I get these error messages, which I don't understand.
I moved setup() and loop() to the top of the sketch, vs buried at the bottom below all the functions, which shouldn't make a difference, should it?
IDE 1.0.6, Win7
Any ideas? Thanks.
// Modified for 1284P pins
// Read/Write from GPS/GSM on Serial1
// Talk to PC on Serial
// Product name: GPS/GPRS/GSM Module V3.0
// # Product SKU : TEL0051
// # Version : 1.2
// # Description:
// # The sketch for driving the gps mode via the Arduino board
// # Steps:
// # 1. Turn the S1 switch to the Prog(right side)
// # 2. Turn the S2 switch to the Arduino side(left side)
// # 3. Set the UART select switch to middle one.
// # 4. Upload the sketch to the Arduino board
// # 5. Turn the S1 switch to the comm(left side)
// # 6. RST the board
// # If you get 'inf' values, go outdoors and wait until it is connected.
