Nippy commented on Jason Short's blog post Ardupilot 2.5 Release Candidate
"Thanks Jason! The new RC2 solved the blue LED problem for me! Great!
The yellow stat doesn't flash but that's not critical i guess.

I'm only at the ground testing phase so it will be interesting to begin testing in the air!"

"I'm trying the 2.5 RC with the red board, NO shield, and the EM406 GPS module.

I have not been able to get the blue LED to show if It has a real sat-lock or not. It just keeps lighting almost instantly.
- Is there a fix for this? Does it work for…"

"Jason, Ok. But shouldn't led blue LED eventually go out if i looses lock?
If I do a proper field setup and get sat lock it never goes off, even in the most impossible conditions.
v246 turned of the light back and forth. Now I can't tell if i really…"

"Ok, tried the new GPS-file and it compiled ok. But still no luck on the blue LED.
If I power the board, with no jumper on, it lights upp (solid) after about 2 sec every time.
If I remove the GPS, the light goes out as expected..."

"Jason, tried your last file, but got the same compile error.
Then I declared GPS_timer in the Ardupilot_25rc-tab:
static unsigned long GPS_timer = 0;
it solved the comile error, but I still get the same behavior as described - solid blue LED,…"

"Jason, I replaced the file but got compile error:
In function 'void GPS_join_data()':
error: 'GPS_timer' was not declared in this scope In function 'void waypoint_event(byte)':

Chris, I'm using the Ardupilot_2.5.0rc.zip ZIP-file from the top of…"

"Thanks for the update! It looks promising!

I just loaded v2.5 on the board and did the needed modifications:

#define SHIELD_VERSION -1 // I have no shield, just the red board
#define GPS_PROTOCOL 1 // I've got the EM406 module

I think there is…"

Nippy replied to Nippy's discussion How to disable RX-inputs? (to stop servo from jittering if weak or no RX-signal)
"Update:
If I turn off the transmitter (or if the signals are weak) I can force the program in WP-mode with this code:
pinMode(4, OUTPUT); //MUX
digitalWrite(4, HIGH); //MUX - Turn on WP-mode

But I'm, still having problem to reject any random signal…"

My receivers (35MHz) usually go nuts when they loose radio signal. If I turn OFF the TX the RX can turn the servos off limits and strip their gears, the motor can suddenly start... Even in Waypoint mode I see that this happens, since you always have…

Nippy replied to Nippy's discussion Ardupilot stops working very often (software crash?)
"Problem solved!
Firts I resoldered the joints - I think they improved, but the problem was still there.

I should have mentioned that I'm short on pigtails, so I had only CTRL and IN1 connected.
But now I stole a pigtail and connected IN2 aswell.…"

"Thanks for the replies!

I'v measured the voltage to 5.1V. Changed the ESC but the problem remains.
I do not have the shield.

How do I monitor ther serial port? I looked in the Arduino Serial port, but only gets garbage.
Is there any useful…"

Problem:When I switch to waypoint-mode (ch5 100%) the MUX-LED lights up and the servos starts reacting (OK).BUT, very often (about 40% of the case) the yellow STAT-LED goes off as soon as I enter WP-mode and everything stops working! No servo…

Nippy commented on Chris Anderson's blog post ArduPilot (Legacy) main page
"I have the ATMega328 WITHOUT the shield. I also have the FMA XY and the Z-sensors (and GPS, FTDI...).

I'm looking for instructions of how to set up (solder) the board. The manual assumes you have the shield.

I found this: Preparing ArduPilot for…"
