One Click - Checkbox Enabled (1)

[Prototype]

Thank you. I was completely missing the binary to hex conversion, which was the whole key. I created the attached Excel worksheet to help people figure out the hex value based upon specific bit values.

I developed and published a Checkbox with bit offset example script.

As it isn't possible (as far as I know) to set a single bit of a byte without also setting the other bits of that byte I have added a feature request at github for that: https://github.com/J2Kbr/GtunerIV/issues/341

Yes, you have to set the full byte and cannot set an individual but. If you want to set a bit, you have to know the the state of all other bits of the byte.

Doing this by code from within a script isn't a problem. I keep the whole byte in a variable and checking/changing the matching bits within it. I can simply write the whole byte back this way.
This isn't working with Prefets / config=control as it isn't possible to read the current state there/set a single bit.
I would like to be able to do that via presets. If I want to be able to toggle different flags/bits via presets I have to put them into seperate bytes to not set the other flags in that byte too I don't want to change..wasting bits.
Thats the reason for the feature request.

That was fast https://github.com/J2Kbr/GtunerIV/issues/341

Operations OR and AND added on Gtuner IV 1.05 revision 1 (I suggest wait the same update be available on Gtuner Air before publish scripts).

Here is how this works:
GIVICFG:#02:04 Assign the hex value 04 to position hex 02
GIVICFG:#02|04 Bitwise OR the hex value 04 with the current value on position hex 02
GIVICFG:#02&FB Bitwise AND the hex value FB with the current value on position hex 02

Found this page explaining AND + OR a bit with examples: https://www.programiz.com/c-programming ... -operators

Awesome

Very nice page about bitwise operations.

In summary: OR for set a bit, AND for clear.
