Got all the parts in. Everything was coming together till I realized I didn't order a connector for the ribbon cable. So close to getting this all put together!

alfa147x

Ordered a ribbon cable from Mouser which according to it's data sheet and my digital caliper is the right size except it has two extra pins. I can then use it to breadboard and then I'll be able to solder it to the perf or stripboard (Can't decide which to go with). Which also will make it a lot ...

Not bad. OS X is seeing it as a US layout Apple USB keyboard. The old style pre-aluminium one by the look of it. The help button is the give away, top left of the home / end etc. block.

Option is the culprit for all those crazy symbols.

I kinda figured out the problems. I don't have the LEDs ...

alfa147x

That's what happens when I plug it in. Working on that currently

alfa147x

Updated all the code and moved over to the new version of the keymap.c layout. Oh and updated CrossPack to the latest version.

I still get this.

if you want to use git they provide quite nice tutorials on how to use it.

concerning the prog_char it looks like it's already a known error: https://github.com/tmk/tmk_keyboard/issues/34
Sweet. Downgraded and it's no longer giving me that issue.

Oh, I see, you've done it that way round :D

If left is K5A, shouldn't "K59, K16, K55" be "K59, K5A, K55" ?

You look about close enough now to compile it and then fix bugs as you find them!

What was the alternative route? And wow thanks for finding that! I was watching The Office's finale while ...

Thank Soarer I've read your reply but got caught up doing other stuff. I'm going tackle the project again tomorrow.

alfa147x

Yeah I was just looking at that. About to tackle it now. Wish me luck

Edit:
Is there a list of those codes?

Edit found it:
https://github.com/tmk/tmk_keyboard/blo ... /keymap.md

Edit:
Hmmm That doesn't match up to what keymap.c has in it.

Any ideas?

alfa147x

Thanks for the help. This is starting to make more sense. Now I'm laying out the keymap.c

This is what I have planned for now:
static const uint8_t PROGMEM keymaps[][MATRIX_ROWS][MATRIX_COLS] = {

Hmm, how much do you know about C's bitwise operators? &, |, ~, << etc.

Looks like you got the relationship between logical bits and physical pins OK.

I know how to read a wiki page:

That code was right from the TMK_Keybaord examples. I'm ...

Each port on the AVR consist of (up to) 8 pins and is controlled by three registers...

DDRx - Direction - each bit sets whether the corresponding pin is input (=0) or output (=1).
PORTx - For an output pin, the output state. For an input pin, setting a bit to 1 activates the pullup resistor for ...

alfa147x

Code: Select all

static void init_rows(void)
{
    // Input with pull-up(DDR:0, PORT:1)
    DDRB  &= ~0b00111111;
    PORTB |= 0b00111111;
}

Any idea how I am suppose interpret this?

Got a link to the code you're looking at?

Just the different keyboard packages that ship with the code.

I was thinking I would map the pins to the code. Then map the keys to rows and columns. Is that right? Am I thinking of the logic wrong?

I think I found it. It's set matrix.c ...

alfa147x

Okay. I have no idea what I'm doing with the code.

Question 1: How do I tell the code which pin which column and row is hooked to?

Amazing what doors the right plastic will open up. I believe the official tool for that kind of thing is a spudger. I've one of those for laptop repair. And a filed thin putty knife for doing the same means of entry to Mac mini's.

I think I found Deskthority through Google, originally. So ...

Got the bread board out. Getting ready to test this thing out today. After getting the Teensy time seemed to move slower BUT I have finally found time to get this thing on the road!

alfa147x

Thanks hasu. I'm thinking I may go the way everyone else does and forget all about a computer visible Fn. It's a key with particular appeal on 60% keyboards, but I think it would be easier to work around it in my design than to emulate Apple's own identity. 5 vs. 6 KRO included.

My Teensy just came in. It's tiny! Wow. Not what I was expecting. Won't be able to breadboard till later this week.

I feel like most boards do that. I'll have to try my MiniLa and see if it does or doesn't.

Yes, I've always wondered why any USB keyboards don't have hubs. It's the perfect place to plug in a memory reader etc. at random, let alone a mouse.

I got one of these little solar powered hubs recently. (For use with iPad and camera connector kit.) A powered hub may be overkill, but keyboards ...
