Use a macro to compute the size of arrays at compile time (#18044)
* Add ARRAY_SIZE and CEILING utility macros

* Apply a coccinelle patch to use ARRAY_SIZE

* fix up some straggling items

* Fix 'make test:secure'

* Enhance ARRAY_SIZE macro to reject acting on pointers

The previous definition would not produce a diagnostic for
```
int *p;
size_t num_elem = ARRAY_SIZE(p)
```
but the new one will.

* explicitly get definition of ARRAY_SIZE

* Convert to ARRAY_SIZE when const is involved

The following spatch finds additional instances where the array is
const and the division is by the size of the type, not the size of
the first element:
```
@ rule5a using "empty.iso" @
type T;
const T[] E;
@@

- (sizeof(E)/sizeof(T))
+ ARRAY_SIZE(E)

@ rule6a using "empty.iso" @
type T;
const T[] E;
@@

- sizeof(E)/sizeof(T)
+ ARRAY_SIZE(E)
```

* New instances of ARRAY_SIZE added since initial spatch run

* Use `ARRAY_SIZE` in docs (found by grep)

* Manually use ARRAY_SIZE

hs_set is expected to be the same size as uint16_t, though it's made
of two 8-bit integers

* Just like char, sizeof(uint8_t) is guaranteed to be 1

This is at least true on any plausible system where qmk is actually used.

Per my understanding it's universally true, assuming that uint8_t exists:

* Run qmk-format on core C files touched in this branch

GMMK PRO (ISO)

A tenkeyless 75% keyboard made and sold by Glorious LLC. Equipped with the STM32 ARM Cortex-M4 microcontroller, with support for rotary encoders and three additional layouts. More info at Glorious

Make example for this keyboard (after setting up your build environment):

make gmmk/pro/rev1/iso:default

Flashing example for this keyboard:

make gmmk/pro/rev1/iso:default:flash

To reset the board into bootloader mode, do one of the following:

  • Hold the Reset switch mounted on the bottom side of the PCB while connecting the USB cable
  • Hold the Escape key while connecting the USB cable (also erases persistent settings)
  • Fn+Backspace will reset the board to bootloader mode if you have flashed the default QMK keymap

See the build environment setup and the make instructions for more information. Brand new to QMK? Start with our Complete Newbs Guide.

Case Screw Replacements

Many users report stripped case screws when disassembling the board.

The stock case screws are:

  • Thread: M2
  • Thread length: ~5 mm
  • Head diameter: ~3.8 mm
  • Head counterbore diameter: ~4.0 mm
  • Head counterbore depth: ~1.9 mm

Most M2x5mm screws should fit fine, although it's best to ensure that the screw head will fit inside the counterbore. For reference, this hex socket head screw from McMaster-Carr should fit nearly flush (head will protrude above the counterbore by ~0.1 mm).
