Firmware General / Remapping of Main Port of Revo

« Last post by wcfung on March 21, 2024, 10:33:24 pm »

I have been flashing several Revolution (regular, not mini) with Ardupilot firmware and running without much problem. Now I want to connect a Jumper R8 receiver to Revolution which has been flashed with Ardupilot firmware. The RC output from the R8 is S Bus. The manual of Revo says the Main Port can accept S Bus, among other protocols.

1) Do I have to re-map the Main port to accept S Bus ?
2) How can I do the re-mapping when Revo is now running Ardupilot fw , not the original firmware ?

Thank you for yr help.

Or maybe S_VOLTAGEMIN = -1

Wild guess after grepping some possibly similar source I have is that there is a setting called S_VOLTAGEMIN
and if you set that to zero it wont display the warning.

More things to try would be moving the warning off screen and setting the cell count to 0.

Of course another way would be to set it all up so that it had a valid voltage.

M24 - the design based on the best performing Hellaplane, in terms of flight hours.

Racer 1 - the lightest and fastest of the 3D pritned Hellaplanes - fully retracting "landing gear".

Some pix of Mini1 and MiniM24 - Mini1 is based on Chris Cornbill's versions of the Hellplane - these have spring based wing swing actuation, and can go from slightly negative to full horizontal mode. I have to admit these are the most fun versions to fly! Mini1 is not the most efficient, but can do some crazy aerobatics! MiniM24 uses the M24 version of wings, which are more efficient.

Showroom / 3D printed eVTOL Hellaplanes

It's been more than 5 years now of designing and building various versions of our eVTOL designs, all using Librepilot to fly.
Since last summer, we've designed and 3D printed 8 different planes, all in PLA. ALthough not as resistant to damage as the carbon fiber and foam versions we've been building up to now, the 3D printed ones are surprisingly lighter and more agile. The wings are mostly 1 layer (0.4mm) thick skin, but in some places reinforced with a double layer in the leading edge. The flight power board has been updated to use 8 wire JST SH cables, which simplifies hookup and increases reliability. They all have two regulators, one for the rcvr and flight controller, the other for servos. Not all the planes are 3D printed, there are carbon fiber spars in the wings and fiberglass rods in the landing gear. One of the beauties of 3D printing is the low cost (it runs less than $10 in PLA to print a plane - power for the printers is solar so its free), and although it takes about a printer-week to print one, replacing damaged parts is generally easy and quick. 3D printing changed my whole method of designing and building - now often I'll just print a part to test when new ideas come up. And when semi-major changes come - we just make a whole new plane! Also takes pressure off in test flying - if we break it, just print replacement parts or a new plane! PLA is not the best for this - a very hot day in the car will soften it, but as we dont usually get those kind of days here, and just taking a little care, its worth it for the low cost. We'll build some in PETG later.

Applications - FPV / Low battery warning in OSD

Hopefully jdl or others can help with this - I thot I had fixed it a few years ago, but can't remember what I did!
I got some new MinimOSD devices and programmed them with what I think is the latest version to to work with next.
Seems to work fine - except I keep getting a low battery warning in the alert area.
Anyone know how to turn that particular warning off?

I have posted a request on dev chat about this.
I would suspect it might be some time before resolution.
