From bcb6e23387290afb64712314bfb095f8d96c1a4e Mon Sep 17 00:00:00 2001 From: JohSchneider Date: Thu, 5 Aug 2021 21:51:24 +0000 Subject: Arm ps2 mouse interrupt (#6490) * ps2_mouse on ARM: an interrupt-version of the ps2-mouse code ported to ARM/chibios * ps2_mouse on ARM: link EXT callback-channel selection to the user defined PS2_LINE_CLOCK * ps2_mouse on ARM: replace DELAY_X defines with hardware-agnostic wait_X * ps2_mouse on ARM: replace chibios-specific defines for the pins/lines with defines from quantum/config_common.h and drop the '_LINE' component from teh define name * ps2_mouse on ARM: expose the software-intterupt port as a user editable define * Update docs/feature_ps2_mouse.md Co-Authored-By: Hugo van Kemenade * Update feature_ps2_mouse.md * use a define to deduce the PS_DATA_PORT instead * reduce all-zero extcfg to oneliner * ps2_mouse: use generic wait instead of avr-delay * Update docs/feature_ps2_mouse.md * ps2_mouse: changes for new chibios version (17.6.0 -> 19.1.0) replacing the legacy externa-interrupt driver with pal-callbacks * ps2_mouse: use PLATFORM_KEY Co-Authored-By: Joel Challis * ps2_mouse: clang-format corrections * ps2_mouse: add systemlocks using the chibios equivalent to AVRs cli: chSys[Unl|L]ock Co-authored-by: Johannes Co-authored-by: Hugo van Kemenade Co-authored-by: Joel Challis --- tmk_core/protocol/ps2_io_chibios.c | 55 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 55 insertions(+) create mode 100644 tmk_core/protocol/ps2_io_chibios.c (limited to 'tmk_core/protocol/ps2_io_chibios.c') diff --git a/tmk_core/protocol/ps2_io_chibios.c b/tmk_core/protocol/ps2_io_chibios.c new file mode 100644 index 0000000000..b672bd1f47 --- /dev/null +++ b/tmk_core/protocol/ps2_io_chibios.c @@ -0,0 +1,55 @@ +#include +#include "ps2_io.h" + +// chibiOS headers +#include "ch.h" +#include "hal.h" + +/* Check port settings for clock and data line */ +#if !(defined(PS2_CLOCK)) +# error "PS/2 clock setting is required in config.h" +#endif + +#if !(defined(PS2_DATA)) +# error "PS/2 data setting is required in config.h" +#endif + +/* + * Clock + */ +void clock_init(void) {} + +void clock_lo(void) { + palSetLineMode(PS2_CLOCK, PAL_MODE_OUTPUT_OPENDRAIN); + palWriteLine(PS2_CLOCK, PAL_LOW); +} + +void clock_hi(void) { + palSetLineMode(PS2_CLOCK, PAL_MODE_OUTPUT_OPENDRAIN); + palWriteLine(PS2_CLOCK, PAL_HIGH); +} + +bool clock_in(void) { + palSetLineMode(PS2_CLOCK, PAL_MODE_INPUT); + return palReadLine(PS2_CLOCK); +} + +/* + * Data + */ +void data_init(void) {} + +void data_lo(void) { + palSetLineMode(PS2_DATA, PAL_MODE_OUTPUT_OPENDRAIN); + palWriteLine(PS2_DATA, PAL_LOW); +} + +void data_hi(void) { + palSetLineMode(PS2_DATA, PAL_MODE_OUTPUT_OPENDRAIN); + palWriteLine(PS2_DATA, PAL_HIGH); +} + +bool data_in(void) { + palSetLineMode(PS2_DATA, PAL_MODE_INPUT); + return palReadLine(PS2_DATA); +} -- cgit v1.2.3
