Anwar, thanks.  I had the wrong wire connected on the ardupilot.  I swapped CTS with Rx and now the IMU gets a lock, but nothing happens when I switch to stabilize and it wont allow any stick movement through.  I'm thinking it is still a mismatch between baud rates.  I know if I use the ArduIMU test program that it only works if I set it to 57600 even though the main loop is set to 38400, so somewhere either in ardupilot or arduimu I need to change baud.

As for your 2. throttle stops, I think that means you have pin11 and pin13 mixed up and need to #define it.  Plus, you might need to change the #define for your PWM type, sequential or random.  Your #1 sounds like baud rate on the Arduino serial monitor

Dear all, I have board 328 (red), EM406, FMA Co-Pilot but no Z and no shield. The code 2.7 is well explained and and this conbination of hardware seem to be enough for a basic UAV. I have loaded the code to the board successfully without any error message. Using the Config Tools I have loaded the GPS data to the board successfully without any error. Currently the problems are:

1. Test Suite via DEBUG_SUBSYSTEM produces not readable characters on the serial monitor (like ASCII characters) that continuously move or scroll?

2. Movig a toggle switch turns on the MUX light and throttle serve stops working?

3. There is no diagram available showing connections for this combinination of hardware. So I am a bit confused about connecting the four servos (Aeliron, Elevator, Throttle and Rudder), the sensor (FMA) and the board?

My radio is Futaba 7CAP converted to 2.4 GHz.

Any one help me please, thanks.

@Harry, These experts have gone far ahead of us and they seldomly look behind to reply your concerns. This is quite frustrating for me also. Please look into the discussion, you may find something related to your concern. But this is very time consuming. Good luck.

I guess that EM406 is junk if trying to use it with ardupilot or ArduIMU.  It only runs at 57600 binary or 9600 NMEA and it refuses to switch between modes.  That makes it worthless.  I will try one more time to get it to work in Sirf at 38400, but I'll have to wait another week just to try that.

The way the IMU is connected to ardupilot is the CTS line of ardupilot is connected to the Tx line of the IMU.  D6 on ardupilot is wired to D8 on the IMU.  If I remove the CTS/Tx connection the IMU blinks.  Connect it back up and the LED turns off and stays off.  What is missing?  Should I replace the CTS with Rx?  I know the GPS will get a fix in a few seconds until it hooks to ardupilot.

This is completely frustrating.  I got everything wired up and now the IMU wont indicate a lock.  I know it will in standalone, but when I hook it up to ardupilot nothing happens.  The ardupilot will change in and out of modes with the CTRL switch, but without that blue LED on nothing happens.  I'm using the EM406 in sirf.  Anybody?

Thanks for your guidance. Overwrite means the previous code/mission is erased? Otherwise the board has a very limitted memory.

Moderator Comment by Graham Dyer on Tuesday

As far as I know both cannot be deleted, only overwritten by new code/mission. Don't think leaving the board unpowered for 10 days will delete the mission, it hasn't on some of my old boards which have be left unpowered for months and still have the mission loaded.

Comment by Anwar Ali Khan on Tuesday

@Graham Dyer, thans but somewhere I red that the mission is stored in EEPROM and it is not possible to delete it once loaded, until the board is left out of power for a week to 10 days?

Using Arduino it will overwrite the code on the board with the new or modified one. Likewise using the Config Tool for a mission plan.
