From 3c58f989295e17d03b66db9a154e02cde7336ece Mon Sep 17 00:00:00 2001 From: Stefan Kerkmann Date: Thu, 14 Jul 2022 11:50:00 +0200 Subject: [Core] PMW33XX drivers overhaul (#17613) * PMW33XX drivers overhaul This combines the PMW3389 and PM3360 drivers as they only differ in the firmware blobs and CPI get and set functions. The following changes have been made: * PMW3389 now gets the same multi-sensor feature that is already available on the PMW3360. * Introduced a shared pmw33xx_report_t struct is now directly readable via SPI transactions instead of individual byte-sized reads, saving multiple copies and bitshift operations. * pmw33(89/60)_get_report functions had unreachable branches in their motion detection logic these have been simplied as much as possible. * The fast firmware upload option has been removed as this becomes obsolete by the newly introduced polled waiting functions for ChibiOS polled waiting * PMW33(60/89)_SPI_LSBFIRST and PMW33(60/89)_SPI_MODE config options have been removed as they don't need to be configurable. * All PMW3389 and PMW3360 defines have been unified to a PMW33XX prefix to reduce code duplication and make the defines interchangeable * Adjust keyboards to PMW33XX naming scheme --- quantum/pointing_device_drivers.c | 87 ++++++++++++--------------------------- 1 file changed, 27 insertions(+), 60 deletions(-) (limited to 'quantum/pointing_device_drivers.c') diff --git a/quantum/pointing_device_drivers.c b/quantum/pointing_device_drivers.c index 8f510b3a98..b7e98e897e 100644 --- a/quantum/pointing_device_drivers.c +++ b/quantum/pointing_device_drivers.c @@ -257,81 +257,48 @@ const pointing_device_driver_t pointing_device_driver = { }; // clang-format on -#elif defined(POINTING_DEVICE_DRIVER_pmw3360) -static void pmw3360_device_init(void) { - pmw3360_init(0); +#elif defined(POINTING_DEVICE_DRIVER_pmw3360) || defined(POINTING_DEVICE_DRIVER_pmw3389) +static void pmw33xx_init_wrapper(void) { + pmw33xx_init(0); } -report_mouse_t pmw3360_get_report(report_mouse_t mouse_report) { - report_pmw3360_t data = pmw3360_read_burst(0); - static uint16_t MotionStart = 0; // Timer for accel, 0 is resting state - - if (data.isOnSurface && data.isMotion) { - // Reset timer if stopped moving - if (!data.isMotion) { - if (MotionStart != 0) MotionStart = 0; - return mouse_report; - } - - // Set timer if new motion - if ((MotionStart == 0) && data.isMotion) { -# ifdef CONSOLE_ENABLE - if (debug_mouse) dprintf("Starting motion.\n"); -# endif - MotionStart = timer_read(); - } - mouse_report.x = CONSTRAIN_HID_XY(data.dx); - mouse_report.y = CONSTRAIN_HID_XY(data.dy); - } - - return mouse_report; +static void pmw33xx_set_cpi_wrapper(uint16_t cpi) { + pmw33xx_set_cpi(0, cpi); } -// clang-format off -const pointing_device_driver_t pointing_device_driver = { - .init = pmw3360_device_init, - .get_report = pmw3360_get_report, - .set_cpi = pmw3360_set_cpi, - .get_cpi = pmw3360_get_cpi -}; -// clang-format on - -#elif defined(POINTING_DEVICE_DRIVER_pmw3389) -static void pmw3389_device_init(void) { - pmw3389_init(); +static uint16_t pmw33xx_get_cpi_wrapper(void) { + return pmw33xx_get_cpi(0); } -report_mouse_t pmw3389_get_report(report_mouse_t mouse_report) { - report_pmw3389_t data = pmw3389_read_burst(); - static uint16_t MotionStart = 0; // Timer for accel, 0 is resting state +report_mouse_t pmw33xx_get_report(report_mouse_t mouse_report) { + pmw33xx_report_t report = pmw33xx_read_burst(0); + static bool in_motion = false; - if (data.isOnSurface && data.isMotion) { - // Reset timer if stopped moving - if (!data.isMotion) { - if (MotionStart != 0) MotionStart = 0; - return mouse_report; - } + if (report.motion.b.is_lifted) { + return mouse_report; + } - // Set timer if new motion - if ((MotionStart == 0) && data.isMotion) { -# ifdef CONSOLE_ENABLE - if (debug_mouse) dprintf("Starting motion.\n"); -# endif - MotionStart = timer_read(); - } - mouse_report.x = CONSTRAIN_HID_XY(data.dx); - mouse_report.y = CONSTRAIN_HID_XY(data.dy); + if (!report.motion.b.is_motion) { + in_motion = false; + return mouse_report; + } + + if (!in_motion) { + in_motion = true; + dprintf("PWM3360 (0): starting motion\n"); } + mouse_report.x = CONSTRAIN_HID_XY(report.delta_x); + mouse_report.y = CONSTRAIN_HID_XY(report.delta_y); return mouse_report; } // clang-format off const pointing_device_driver_t pointing_device_driver = { - .init = pmw3389_device_init, - .get_report = pmw3389_get_report, - .set_cpi = pmw3389_set_cpi, - .get_cpi = pmw3389_get_cpi + .init = pmw33xx_init_wrapper, + .get_report = pmw33xx_get_report, + .set_cpi = pmw33xx_set_cpi_wrapper, + .get_cpi = pmw33xx_get_cpi_wrapper }; // clang-format on -- cgit v1.2.3
