"hi, i'm also interested for these info! i do have a 2560 mega , and i would like to use it as a quadcopter autopilot! is it possible, i mean without recoding everything ftom scratch?"

Justin replied to Justin's discussion Extract data between commas"hi, just letting you know i got it working, and i have the exact value printing out on my serial connection. thanks"
Bot Thoughts replied to Justin's discussion Extract data between commas"Ok, gotcha.
If you are programming using Arduino environment one option is to use TinyGPS. It parses NMEA output and you can then query lat/lon and ignore the rest.
Otherwise, you have to work out how to get the string into memory to parse, then run…"
Justin replied to Justin's discussion Extract data between commas"Im building essentially an ardurover, but im using an 'offtheshelf' purchased arduino mega2560.
It includes a gps and compass... so what im trying to do by finding these lat and long values is mathematically work out heading and steer…"
Bot Thoughts replied to Justin's discussion Extract data between commas"Well... now's a good time to learn :) I think you'll be fine getting it to work. Just post more questions here and I'll do what I can to help.

Justin replied to Justin's discussion Extract data between commas"I havent tested it, but from what i can see, it looks fairly clear and i might use some of it (the split code).
thanks, although, is there any other possible suggestions you can think of how to do it? because im not the most fluent in programming,…"
Bot Thoughts replied to Justin's discussion Extract data between commas"Um, ok, sure. How about the code snippets I posted? Will those work?"
Justin replied to Justin's discussion Extract data between commas"ive been looking at the tinyGPS code, but it doesnt seem to work for my use in my project."
Bot Thoughts replied to Justin's discussion Extract data between commas"Would TinyGPS be of use here?
I wrote a split() routine that is similar to C strtok() and perl split so that I could read in parameters from a config file:

"@Justin,
I would look at the schematic of the APM1 board and make your inputs and outputs (servos, esc, compass, gps, etc) similar to that of the APM1. The I would look at the coding that JLN has modified for the ArduRover project to get an idea of…"

Hi, I am working on a project for uni where I have to make an UGV capable of waypoint navigating only.I have a standard Arduino mega 2560, (as in an 'off the shelf' bought, non- ardupilot board) with a GPS shield and an SD shield that works currently, logging the gps data.I only have one throttle, and one servo for steering. (k.i.s.s.)Now given the waypoint setup in the APM, is there anyway that i can connect up two pwm controls (being steering and acceleration) and have it steer and accelerate…See More
