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 --- docs/feature_ps2_mouse.md | 28 ++++++++++++++++++++++++++-- 1 file changed, 26 insertions(+), 2 deletions(-) (limited to 'docs/feature_ps2_mouse.md') diff --git a/docs/feature_ps2_mouse.md b/docs/feature_ps2_mouse.md index 8e84e22d8a..00c7ee72ee 100644 --- a/docs/feature_ps2_mouse.md +++ b/docs/feature_ps2_mouse.md @@ -50,7 +50,7 @@ In your keyboard config.h: #endif ``` -## Interrupt Version :id=interrupt-version +### Interrupt Version (AVR/ATMega32u4) :id=interrupt-version-avr The following example uses D2 for clock and D5 for data.
