"Hi, yup. Pins forward, lens down. Familiar with pid tuning but that's redundant if of-loiter is not finished. Are there different pids for optical flow than there are for gps loiter? I'll post a picture in a few mins. Has anyone got…"

"If I understand correctly, OF_Loiter is still a work in progress and we are recommended against using it. However, that is the only mode that uses the OF sensor. I'm working to build a quad that can hover inside for a very long time. I have…"

Gareth Evans replied to Gareth Evans's discussion APM 2.0 Optical Flow
"Cool, thanks Thomas. That was what I thought, I was getting x/y data in the of test in the console. As for flight modes, what modes does it work in? Only OF_Loiter? Is that "done"? When I got into a hover and switched on OF_Loiter the quad…"

Thomas the Nerd replied to Gareth Evans's discussion APM 2.0 Optical Flow
"The optical flow sensor DOES work on the APM 2.0 board. However, due to an incompatibility between the sensor and the APM logic, it's not simply "plug and play" like the sonar. Just follow the diagram, and it will work. You will have…"

APM 2.0 Optical Flow

Can someone confirm if OF_Loiter and the OF sensor available on the DIY Drones store works with the APM 2.0 (not 2.5)The wiki is ambiguous  there's a wiring diagram for the APM 2.0; but the comments say it doesn't work due to a difference in voltage (3.3v vs 5.0v) and that the next hardware revision is required.The OF test feature in the console seems to give data when you wire the sensor as per the diagram, but I am unsure if OF_Loiter is implemented in 2.8.1 and if it isn't, whether the OF…See More

"Fixed it.  The issue was that I had some of my wires flipped around.  Note to self: check all the wires carefully and make sure you know which is which. It still didn't work after I identified the cables and got them right because I…"

"Hi,  I'm building a hex with those exact same motors (3536-910s) and was looking for ESCs that could do 40a and were simonk compatible, so thanks for posting your links in the comments. I checked out your prop test data, I can't find…"

Gareth Evans replied to Gareth Evans's discussion 900mhz 3dradio + osd - mission planner won't connect
"If I disconnect my minimosd, it works. However, I must stress that my OSD is working, and I do not have the osd TX pin wired to the apm2 RX pin. There are only 3 wires connecting my OSD to the apm2."

"If I plug my air side modem in via FTDI and ground via USB, then connect a putty serial session between them, whatever I type on ground side is displayed on air side and vice versa. Basic communication seems to be working. "
