I did some weird math that converted the heading that comes from the keypad, to the number the heading hold PID wants.
360*(1 - (floor((keypadHeading - 1) / 360) + (keypadHeading - 1) / 360))=desiredHeading

Hey tomato, thanks for bringing that to my attention. You are right, there is definitely an error in the heading output value not matching up with the world heading. I don't have a lot of time today to work on it, but it looks like the displayed output heading is showing 180 when the vessel is facing north. See this image:

So it seems it is off by 180 degrees. I will get this fixed as soon as I have time and re-upload. Until then, the hold functionality does still work as expected.

hi leonard, i added a keypad to this microcontroller but noticed there was some issues. i checked with tooltips and realized the heading thats being used is.. not really whats normally considered heading.
For further reference you can use this function to convert compass to heading, where X=compass.
ceil(((1-x)%1)*360)
How are you using the compass? I need to get my keypad to output desiredheading to the logic. Ie; when I was going heading 240 (actual) the script was saying heading was 122 or something in that range.

@Ozruul, are you wanting to override the set heading with a number input? If so, you'll have to modify it to add a new input node that allows you to set the heading from a number input. As it is currently, the only way to modify the set heading is to toggle it on (which will set the heading hold to your current vehicle's heading), or by adjusting it left/right with the momentary inputs (Heading Adjust Left and Right inputs).

how do i make it passive? so it'll always hold heading but i can override with my own commands

ok ty :D

It should yes. Some users have told me they have added it to their helis

does this work for helicopters

This one is a bit different from your typical keypad heading set system. Basically you point your vehicle in the direction you want to hold heading, then activate the System Enabled input via a button or other toggle input. The MC then automatically sets your current heading to the held heading. Then you can use the adjust left or right to fine-tune the direction you want to travel. If you would rather input a heading in any direction from a keypad, this may not be the most optimized for your use, however, it would not be difficult to add an additional input to this MC that serves as the "held" heading, while keeping the rest of the logic the same.

Why dont you have a number input for the heading?

Where do i connect everything

Great, thanks. Wont be done for another few weeks

Yea for sure. Let me know when you upload it. I'd like to check it out.

Can I use this in a future workshop submission? You will be credited in big blue letters

Oki thanks !

Hmm I do not but this is a good variation I should probably try to post. I can see how using a number input block to set the desired heading would be useful.

Do you have a version that could take in a value from 0 - 360 for the desired heading, tryna make a ww2 torpedo for my u-boat

You can hook it up to a display so you can see what heading the microcontroller will be trying to hold. It is not required to use, just nice to be able to see what heading that is set.

Where I plug in current heading output degrees

You don't actually have to connect that to anything if you don't want. It is just an output there in case you wanted to show the stored heading on a gauge or screen in your vehicle's cockpit.

where do i connect the stored heading??

ok

I'm not the best at PID tuning myself but there are lots of good guides out there.

how do you think i should tune it

It drifts a bit for me but it does eventually re-correct itself. Try tuning the PID inside the MC a little more to your craft. That will hopefully help it perform a little less sluggish.

ok

Cool I'll try and take a look at it tonight

here i was ganna put it on the workshop anyways

i cant message you without friending you friend me temporarily

ok

Might have to just upload it to the workshop as unlisted and send me a pm with the workshop link. You can take it down after I have a chance to save it for testing.

somthing else is wrong with it though

i think i found out why, its because while the gyro is on the heli tilts left and right, i dont know why. do you know how to fix this

how do you want me to do that

@ecwskier if you want to send me you creation privately I can open it up and see why it is not working.

doesnt work to good with my helicopter it over corrects and slowly goes back like really slow

Thanks for the link-back *****! Happy that this MC is helping so many creators out there.

Thank you for your creation. Incorporated into my helicopter .

Simple, works and if all you want is a go-that way only needs one button on the space demanding dashboard. Thanks.

Nice controller. Works well in my helicopter.

This microcontroller is so useful, i have no complaints whatsoever

Best part was i took my survey chart for the ocean floor and it just merged perfectly with this. made it nearly fully automatic for surveying the bottom

Thank you Martin! I am glad it is useful

Thank you for making such a simplistic and easy controller that can be used in many different creations from subs to boats and maybe even planes! i just want to thank you for making an awesome controller, that ive used basicly since it came out

Just found this controller and started using it for my submarines, works great!

My boat goes left and right when I turn heading hold on

The best stand-alone Heading-Hold I came across until now.
Easy to use and modify to my needs and effective in every aspect

When I Tested It The Stored Heading On That Was Connected To A Dial Continued To Say 0.

works amazingly, even though i'm using it for a helicopter. great job!
