A few people have been wanting to look at the path i took to get telemetry data from the above combination of hardware.





I used the ArduIMU v1.7 code, and the ArduPilot 2.6.2 code (it was freshest at the time).



ArduIMU

-----------------

#define BOARD_VERSION 2 // 1 For V1 and 2 for V2

#define GPS_PROTOCOL 2 // 1 - NMEA, 2 - EM406, 3 - Ublox We have only tested with Ublox

//yes i set the EM406 here



#define PRINT_GPS 1 //Will print GPS… Continue

Good luck try not to get any juice on the hardware :)

After 2 months of using my 406 at home for testing it has stopped working on both imu and ardupilot. So i guess it's a hardware fault with the 406.

Out of interest, have you set your 406 to 38k or modified the imu and ardupilot to 57..k?

Richard,

Here is a pic of the connector from the USBtinyISP to the ArduIMU.

connect the 6-pin ISP connector to the arduimu as follows:
6-pin connector from the bottom, ribbin cable comes out
the right side, red wire on top (near pin 1):
5V (2) o o (1) MISO ----ribbon cable (red wire)
MOSI (4) o o (3) SCK ------ribbon cable
GND (6) o o (5) RESET --ribbon cable

On the Arduimu, the corresponding pins are clearly marked:
GND 5V MISO MOSI (pwm0) (pwm1) (d8) RST

- start arduino IDE as root: "sudo ./arduino" (I'm on Linux).
- menu: Tools -> Burn Bootloader -> w/usbTinyISP
- red light turns on on ISP. Turns off when finished.

Happy hacking,

-- Yann

PS: I also have an EM406 GPS.

Thanks, not sure why i was being blind, deaf, and dumb earlier (well not deaf anyways). I finally saw the pinouts for the 6 pin connector, then was wondered about the power. This picture explains it (yes, you have the USBtinyISP power jumper on).

By the time this project is where i want it.. i bet every possible solder point will have a pin on it. (grin)
