* Use a macro to compute the size of arrays at compile time (#18044)Jeff Epler2022-08-301-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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>

* Add minimal STM32F103C6 support (#17853)Sergey Vlasov2022-08-115-1/+28
| | | | | | | | | | | | | | | | | | | | | | | | Unfortunately, the crippled versions of “Bluepill” boards with STM32F103C6xx chips instead of STM32F103C8xx are now sold all over the place, sometimes advertised in a confusing way to make the difference not noticeable until too late. Add minimal support for these MCUs in the common “Bluepill with stm32duino” configuration, so that it could be possible to make something useful from those boards (although fitting QMK into the available 24 KiB of flash may be rather hard). (In fact, I'm not sure whether the “STM32” part of the chip name is actually correct for those boards of uncertain origin, so the onekey board name is `bluepill_f103c6`; another reason for that name is to match the existing `blackpill_f401` and `blackpill_f411`.) The EEPROM emulation support is not included on purpose, because enabling it without having a working firmware size check would be irresponsible with such flash size (the chance that someone would build a firmware where the EEPROM backing store ends up overlapping some firmware code is really high). Other than that, enabling the EEPROM emulation code is mostly trivial (the `wear_leveling` driver with the `embedded_flash` backing store even works without any custom configuration, although its code is significantly larger than the `vendor` driver, which may also be important for such flash size).

* ChibiOS: use correct status codes in i2c_master.c (#17808)Stefan Kerkmann2022-07-281-2/+2
| | | | msg_t is MSG_OK in the success case and either MSG_RESET or MSG_TIMEOUT in case of errors. So actually use them in the comparison.
* Chibios: Stop I2C peripheral on transaction error (#17798)Stefan Kerkmann2022-07-261-15/+24
| | | | | | | | | | | | | | From the ChibiOS HAL I2C driver pages: After a timeout the driver must be stopped and restarted because the bus is in an uncertain state. This commit does that stopping explicitly on any error that occurred, not only timeouts. As all the i2c functions restart the peripheral if necessary it is safe to do so.

* [Core] Use polled waiting on ChibiOS platforms that support it (#17607)Stefan Kerkmann2022-07-115-5/+22
| | | | | | | | | | | | | | | | | | | | | | | | * Use polled waiting on platforms that support it Due to context switching overhead waiting a very short amount of time on a sleeping thread is often not accurate and in fact not usable for timing critical usage i.e. in a driver. Thus we use polled waiting for ranges in the us range on platforms that support it instead. The fallback is the thread sleeping mechanism. This includes: * ARM platforms with CYCCNT register (ARMv7, ARMv8) this is incremented at CPU clock frequency * GD32VF103 RISC-V port with CSR_MCYCLE register this is incremented at CPU clock frequency * RP2040 ARMv6 port which uses the integrated timer peripheral which is incremented with a fixed 1MHz frequency * Use wait_us() instead of chSysPolledDelayX ...as it is powered by busy waiting now. * Add chibios waiting methods test bench

* [Core] Update mpaland/printf to eyalroz/printf fork (#16163)Stefan Kerkmann2022-07-073-1/+4
| | | | | | | | mpaland printf implementation was abandoned in ~2019 and the fork by eyalroz is now regarded to be the goto replacement of it. So this commit incoporates the changes needed to use this fork in QMK. Note that pointer ptrdiff_t is always supported since commit 51c90f93a97fdaef895783ecbe24569be0db7cb8
