Rod Davis replied to Randy's discussion PixRacer with Ardupilot
"Ok, I think I may have found the problem. I looked at the signal coming from the D4R-II to the Pixracer when power by the USB port vs battery power through the ACSP4. The USB wave was pretty clean but when powered through the ACSP4, not so much.…"

"@Otto Kung,

I don't have a scope to check the signal voltage. Been thinking about getting a little portable one and I may have to do that. I was wondering if it could be a power issue, but the setup is pretty simple and the Pixracer is always…"

"I'm using the old D.Port telemetry (D4R-II) but S.Port should work the same way. You need the FrSky S.Port cable from AUAV. It plugs into the top connector on the right side next to the Wifi connector. You then set SERIAL4_PROTOCOL = 4. I have…"

"@Otto, yes, I don't like the Vib X values. It's not clipping but they are too high. I did a semi-hard mount with bobbins to see what it would do, but I'm going to have to rethink the dampening.
Also, I know the tuning is off. Where's some…"

"That's odd. I just looked at the log and the FMT messages are there. The log file was generated on 3.4-rc2. I'm just using one of the modified TH9Xs 3DR shipped with the Iris+."

"I wasn’t sure if I should be posting it here or over in the discuss.ardupilot.org site.  I’m having trouble with radio timeouts between a D4R-II and Pixracer. This has been an ongoing intermittent issue.
I have tested with and without the Wifi…"

Rod Davis replied to Randy's discussion PixRacer with Ardupilot
"I just tried it with the setting BRD_SAFETYENABLE=1. (Hadn't seen your post yet.) Basically, had the same behavior. When the battery was plugged in the second time, I got a long low tone. The safety switch was slowly blinking. I pressed the button…"

"Yes, I loaded the latest using ctrl-q this morning. The part that seems odd is that the safety switch led doesn't go on solid when it goes into esc calibration. It does a slow double blink."

Rod Davis replied to Randy's discussion PixRacer with Ardupilot
"Loaded the latest code and still can't get the ESC calibration to work. The first time I plug in the battery with the throttle high, the safety light goes solid (BRD_SAFETYENABLE=0) and I get standard tones. When I then disconnect and reconnect the…"

"Yes, i specified port 14550 and it just waits for a UDP connection. It appears that MP expects the Pixracer to already be sending to that port. I can only assume that it knows the IP address since it gave it out via DHCP. What am I missing?"

Rod Davis replied to Randy's discussion PixRacer with Ardupilot
"I must be doing something wrong. The ESP8266 does broadcast the PixRacer network and allows wifi connection giving out DHCP. I can ping it fine but I can't connect with MP or Tower and when I do a port scan I find nothing open. Are there parameters…"

Rod Davis commented on Jerry Giant's blog post P9X autopilot, a revised pixhawk
"I don't understand the problem. You have a bunch of people that gave their time and IP to a project so that others can stand on their shoulders and extend what they had done. All they ask in return is that those extensions are shared back for the…"

"I've stayed out of this up to now, since I don't have a dog in this fight, but I will throw in my two cents anyway as a potential customer. I have not purchased any of the clone products because I felt I should spend my money supporting the folks…"
