| * | [Core] Use polled waiting on ChibiOS platforms that support it (#17607) | Stefan Kerkmann | 2022-07-11 | 1 | -3/+2 |
| | | | | | | | | | | | | | | | | | | | | | | | | | * 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] Add Raspberry Pi RP2040 support (#14877) | Stefan Kerkmann | 2022-06-30 | 1 | -0/+57 |
| * Disable RESET keycode because of naming conflicts * Add Pico SDK as submodule * Add RP2040 build support to QMK * Adjust USB endpoint structs for RP2040 * Add RP2040 bootloader and double-tap reset routine * Add generic and pro micro RP2040 boards * Add RP2040 onekey keyboard * Add WS2812 PIO DMA enabled driver and documentation Supports regular and open-drain output configuration. RP2040 GPIOs are sadly not 5V tolerant, so this is a bit use-less or needs extra hardware or you take the risk to fry your hardware. * Adjust SIO Driver for RP2040 * Adjust I2C Driver for RP2040 * Adjust SPI Driver for RP2040 * Add PIO serial driver and documentation * Add general RP2040 documentation * Apply suggestions from code review Co-authored-by: Nick Brassel <nick@tzarc.org> Co-authored-by: Nick Brassel <nick@tzarc.org> | |||||
