hubosd firmware request

[UncleMcNutz]

request for hubosd support, i would like to use mwosd on my hubosd if at all possible as the current gui overlay for the stosd8 firmware is very limited.

@UncleMcNutz HUBOSD and various derivatives are really nice. I actually was looking at one of them tonight on BG.

However, supporting HUBOSD in MWOSD is very difficult, if not impossible.

Main reason is that HUBOSD employs STM8, which is a completely different from ATmega328 that MWOSD is currently supporting. It's like porting a software running on a Mac to a Windows PC.

Slightest possibility is that if there is an Arduino compatible IDE for STM8, then we might be able to do it. I have done the similar porting onto Teensy 3.1 using Teensyduino. It actually was an overnight job thanks to the rich resource provided by 32-bit ARM core on Teensy 3.1, but porting to STM8 would be more painful due to the 8-bit core, and it's no trivial task.

[UncleMcNutz]

thought it may have been difficult, though regarding pdb's and osd's on one board do you know of any that supports mwosd? i've looked at this one but it's bad, has bad reviews and is the only one I've found so far with mwosd compatible components.

[jflyper]

@UncleMcNutz I occasionally surf the net to look for exactly what you are looking for, but never had a luck.

[UncleMcNutz]

https://flyinglemon.eu/glowna/25-lemoncore-pro-pdb.html have a look at this it's an atmelmeag32p pased chip so it should be able to be flashed with mwosd? though i'm not too keen on the price for a chip that size it's seams overly expensive.

[jflyper]

@UncleMcNutz Yeah, I've took a look at it, but it lacks MAX7456 OSD chip. I think it's using LM1881 video sync generator and M328 is explicitly injecting overlay video signals.

[UncleMcNutz]

damn all these limitations for the perfect pdb osd mix

[jflyper]

Yeah, the current trend is the FC+OSD integration.

I suppose you have an FC that you really want to stick with? What are you flying?

[UncleMcNutz]

im flying an xracer f303 v3.1 love it to bits, i don't really like having a lot of stuff on the fc as it always seems to add cpu latency, and with the weighted pid code of betaflight 3.0x you need to trim the fat a bit so it doesn't overload the fc

[jflyper]

@UncleMcNutz I ran across this

Integrated Power Distribution Board PDB Built-in OSD Dual BEC for Naze32 F3 CC3D

Although I can't confirm it has M328P + MAX/AB7456 combination, solder land patterns suggest they are there.

[ShikOfTheRa]

It also says pre-loaded with MWOSD 1.5 - so should be good

[jflyper]

Ah, and someone commented "First try, not bad but for a newer version of the PDB there is a lot room for enhancements".

Are you going to give it a try?

[ShikOfTheRa]

Not for me - I have joined many others and am fed up with JST1.0 connectors. I just read his review - guess he's the same too. Now prefer direct solder or pcb pins.

[jflyper]

Ah, I was addressing @UncleMcNutz

[ShikOfTheRa]

Ah sorry!

[UncleMcNutz]

i think i did have a look at this before but it's almost as much as my flight controller lol, and i'm really not a fan of jst 1 connectors, was looking at the rrosd which isn't much difference between the hubosd, though flying the hubosd a fair bit more and ive just got used to the minimal style of it, though still would like mwosd for the added functionality of the artificial horizon

[jflyper]

How about designing your own pdb board with provision to accept regulator and osd components?

Something like this.

[ShikOfTheRa]

Unfortunately not much we can do her e- unable to support the hardware so closing this as an active request.

:(
