From 3f5dc472965e6a5b8efe60e33c7b6c2d18d92008 Mon Sep 17 00:00:00 2001 From: Stefan Kerkmann Date: Mon, 11 Jul 2022 15:17:05 +0200 Subject: [Core] Use polled waiting on ChibiOS platforms that support it (#17607) * 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 --- keyboards/handwired/onekey/teensy_2/config.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'keyboards/handwired/onekey/teensy_2') diff --git a/keyboards/handwired/onekey/teensy_2/config.h b/keyboards/handwired/onekey/teensy_2/config.h index b83262ef05..437c597f29 100644 --- a/keyboards/handwired/onekey/teensy_2/config.h +++ b/keyboards/handwired/onekey/teensy_2/config.h @@ -29,3 +29,6 @@ #define RGB_DI_PIN F6 #define ADC_PIN F6 + +#define QMK_WAITING_TEST_BUSY_PIN F6 +#define QMK_WAITING_TEST_YIELD_PIN F7 -- cgit v1.2.3
