Great I'm very glad good stuff will be coded for this f3discovery platform...Since my planes are big enough to carry it, it will make a nice affordable FC solution...I could afford to put one a piece in all of my planes..

I have already a list of wishes for features if someone wants to listen to me

Maybe it would help to add some code which disables all PWM outputs while saving a setting to flash (this would also imply not to save at all when armed).

I dont get this one reproduced. Can you send me your settings please?

Here you go. Let me know if I can do anything else to help track down the issue.

This is good for a laugh, maybe

Yesterday, I was on the Farnell [element14 in Australia] website and the STM32F3- Discovery was showing up in stock.

So I ordered 2.

I also ordered 10 shock isolating rubber grommets, which also showed in stock.

Today by Toll Overnight Priority I received a large satchel with a huge amount of bubble wrap and 9 small rubber grommets.

I x rubber grommet on backOrder, 2 x F3 Discovery on BackOrder.

Lucky it is free shipping.

Just ordered a couple of these super cheap boards from Farnell UK as they have168 in stock. Looking forward to seeing what there like. I am building a second quad for fun flying.

Received my 2 back ordered F3 Discovery boards from Element 14l, yes these did come to Element 14 in Australia via Farnell UK.

I got notification that my two F3's shipped from Newark yesterday too, I guess I need to get busy soon.

Just got mine today and here is it working

Discovery F3 running OpenPilot (0 min 38 sec)

I saw several people were working on PCB for the F3Discovery board. Is it possible to get files for released board ?

I have build one with normal dot matrix board and some thin servo wire as per diagram.

Is there a way to use this with ppm-sum ? Of do I need to just jump some pins somewhere maybe. Has anyone tested this yet.

You should be able to reconfigure the first PWM input to a PPM input.
You can do this in the GCS at the hardware configuration tab.

Great, didn't think of that doh. Cheers will report back with progress

Ok I connected it via the rcvr port and selected ppm but get nothing in the stick calibration window. If I use the std PWM setting and 4 servo wires from 4 channels of the receiver I can go through the stick calibration wizard ok ie it asks for throttle input and it senses it them moves on to roll as and so on. Then when I get the stick reverse checking part the on screen sticks don't move at all and on the main screen the bars don't move. Anyone got any ideas what could be wrong please ?

It could help if you gave us some more information.

- What receiver are you using?
- is PPM selected in the transmitter and in the Ground Control Station (GCS).
- Do you have the PPM of this receiver working on another machine
- What version of the GCS are you running. You should only use the version posted in the Wiki by Lilvinz.

Check in the UAVObject browser if you can really see that PPM output is active.

Concerning PWM; The bars in the input module of the GCS only move when the manual calibration is active. If they move during the calibration procedure than you should be fine. You could assign one of the channels to the flightmode switch. You should see the flight controller status changing in the flight data window.

A general rule of precaution; Remove the propellors from the motor when you do the initial setup.
