Martin replied to Dave C's discussion Arducopter Tuning Guide
"Yeah, that is of course an option. I used the "Extended Tuning" tab...
However the full param list is kinda bad to work with but I guess it will do.
Need to look closer into the code, to find the magical 0.008! =)"

Martin replied to Dave C's discussion Arducopter Tuning Guide
"Hi, I've always used this method for tuning my quads, but after upgrading my mission planner (v1.3.31) I can no longer set the P, I all the way to zero.
For example, the minimum P I can set is 0.008. 
Maybe setting such a low value will be more or…"

Nice work btw!"

Martin replied to Jesper Rooth's discussion Telemetry - OpenLRS and APM
"I've sent a pull request to Kah for this. 
He's got lot's of good things todo (apart from mavlink related stuff) but he said that he was going to look over it(it's a clean merge), so theoretically it's quite near mavlink support in main. Or atleast…"

Martin replied to Andrew Dankers's discussion MAVLink data displayed on OpenTX (9X/9XR/etc) radio screen via OpenLRS, plus telemetry pass-thru to PC
"Unfortunately, another RX module would not work, since the RX module is synchronized with the TX. Also it's the RX on the plane sending the telemetry data for the TX to receive. So what you would in theory need is another openlrsng module (let's say…"

Martin replied to Jesper Rooth's discussion Telemetry - OpenLRS and APM
"I've set aside some time for actually trying to rewrite my stuff without libraries etc. so it should be closer related to kah's original branch... I hope this will also sort out the issues you guys are having. @badzz: once I get it working properly…"

Martin replied to Jesper Rooth's discussion Telemetry - OpenLRS and APM
"Hmm, I got it wrong in my last post, been a while I was looking into the code and too many projects going on =). I already do make up the radio info packet from standalone code (to save flash and SRAM), and have my own parsing of mavlink 1.0 packets…"

"Hi, cool that you've found usage for my branch of openlrsng. The assumption you've made about outdated MAVLINK defs could be right. Did a quick diff and there are some differences in the xml message definitions between what I've been using in my…"

Martin replied to AlanGP's discussion Using the LRS back channel for APM Telemetry
"Checkout my fork of OpenLRSng: https://github.com/gitsly/openLRSng
It has been specifically developed to convert your OpenLRS device to a combined RC / Telemetry system.
The thing it does primarily is to enable you to specify transparent serial…"

Martin replied to Martin's discussion Compass setup drives me mad
"Hmm, looking at the code (here at work =), important stuff this is. I can see some fishy things going on:
In compass.h (libraries):
#if CONFIG_HAL_BOARD == HAL_BOARD_APM1# define MAG_BOARD_ORIENTATION ROTATION_ROLL_180

So my default mag orientation…"

"Yeah, me too. I'll try to turn it upside down (components facing down) when I come home from work. Altough it goes against all logic... I'm attaching a picture of the current installation, compass i secured with hotglue in a "snusdosa" mounted…"

Hi, I'm trying to setup my quad, using an old APM1 which I bought broken but was able to repair by replacing some parts (mainly ADC converter IC on shield, and a replacing the PPM signal converter AtMega238). Everything is working except that I…

Martin replied to Flo's discussion Guided Mode manual?
"Hmmm, I've experienced the same problem with Fly to here ALT not doing anything!
I had my quad approx 20m up in the air in loiter.
from here I can set Fly to here (no alt) which works as expected, mode is switched to guided automatically and quad…"
