Re: Arduino-based mode-switch for APM
Just wondering, did you find a suitable PCB fab ?sgofferj wrote:There was some good resonance on DIYD. I might have a bunch of PCBs made if I find a fab which does small numbers with reasonable prices.
Thanks

Re: Source hardware getting started
I thought that. It's like lego mindstorms, but more advanced.
Later.
For now I'd like to make my own pcb, preciselly voltage and current regulators (current is for LED).
As said, one based on ADP2303.
Is there a PCB design software easier and simpler than Eagle ?

Re: something weird happening flashing r804 Frysky
if you write the complete eeprom from one radio to the other, yes you will have to calibrate. If you just want to copy models, backup both eeproms, open both in eepe and just drag models from one to the other to copy them.. Then just make sure you flash the right eeprom to the right radio.. ;) Smar...

Re: something weird happening flashing r804 Frysky
Thanks to both. If you read the EEPROM using eepe, change the default channel order, then write EEPROM back, this should work. The default channel order should be used when you create a new model. I flashed for the first time a new 9X. So no EEPROM to read. There was one model pre-set, a basic plane...

Re: something weird happening flashing r804 Frysky
I'm using a 9X with er9x (r780). I'm currently preparing another 9X, this time for onboard telemetry. So I just soldered the 6 wires for flash and reroute pins 41-42. And I flashed er9x-FRSKY (r805). All inputs seem to react as expected (switches and pots), so that first hw job seems OK. But, the ne...

Re: EEPROM size
The size are from the files on my computer.
But I know now why they're smaller: it happends when changing the splash screen.
The new r804 is now even smaller: 129k
So solved, thanks.

All previous firmwares were about 133k also (r744, r760). But now they seem to be about 150k (r788, R803, r804). Can...

Re: A missing basic feature ?
OK thanks. I think I got it and will play with weights and limits. But the whole point is that on a real model you don't care much about how the servos actually move. You don't measure throw on the servo itself, you measure it on the control surface (because that's what matters). Ideally, you: - Set...

Here is the second diagram.

A missing basic feature ?
I'm using my 9x quite basically since about 6-8 months. I just realized now there is a very basic feature missing: trims and/or subtrims (real ones, at least on my mind). It looks like the trims and subtrims and offsets, etc, just move the servo neutral point but do not shift the whole servo travel ...
