* 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: https://stackoverflow.com/questions/48655310/can-i-assume-that-sizeofuint8-t-1 * Run qmk-format on core C files touched in this branch Co-authored-by: Stefan Kerkmann <karlk90@pm.me> |

Adafruit MacroPad RP2040
A RP2040-powered Macropad with a 3x4 layout.
- Keyboard Maintainer: Jpe230
- Hardware Supported: Adafruit MacroPad RP2040
- Hardware Availability: Barebones kit Starter Kit
Make example for this board (after setting up your build environment):
qmk compile -kb adafruit/macropad -km default

Features
- Raspberry Pi RP2040 Chip + 8MB Flash memory - Dual-core Cortex M0+ at ~130MHz with 264KB of RAM.
- 3x4 Mechanical key switch sockets - accepts any Cherry MX-compatible switches. Individually tied to GPIO pins (not matrix wired)
- One NeoPixel RGB LED per switch, on north side.
- Rotary encoder, 20 detents per rotation, with push-switch on GPIO pin. Push switch is also used for entering bootloader mode when held down on power-up or reset.
- 128x64 SH1106 Monochrome OLED display - On high-speed hardware SPI port for quick updates.
- 8mm Speaker/Buzzer - With Class D amplifier and RC filter, can be used to make simple beeps and sounds effects. (Unsupported for now)
- STEMMA QT Connector - Allows adding any I2C sensors/displays/devices with plug-and-play cables.
- Reset button - On the side, for quick restarting, press it twice to enter bootloader.
- Four M3 mounting bosses - Make custom enclosures easily.
Bootloader
Enter the bootloader in 4 ways:
- Bootmagic reset: Hold down the key just bellow the rotary encoder push-button on power-up.
- Physical reset button: Press twice the button on the side while the board is connected.
- BOOT button Hold down the rotary encoder push-button on power-up or reset.
- Keycode in layout: Press the key mapped to
QK_BOOTif it is available.
