From 7f7364c55912879baaff8fafca550d02f17b4d44 Mon Sep 17 00:00:00 2001 From: Dasky <32983009+daskygit@users.noreply.github.com> Date: Mon, 27 Dec 2021 01:05:51 +0000 Subject: [PATCH] [Core] Split support for pointing devices. (#15304) * Draft implementation * formatting * fix combined buttons * remove pimoroni throttle * sync pointing on a throttle loop with checksum * no longer used * doh Co-authored-by: Drashna Jaelre * switch pimoroni to a cpi equivalent * add cpi support * allow user modification of seperate mouse reports * a little tidy up * add *_RIGHT defines. * docs * doxygen comments * basic changelog * clean up pimoroni * small doc fixes * Update docs/feature_pointing_device.md Co-authored-by: Drashna Jaelre * performance tweak if side has usb * Don't run init funtions on wrong side * renamed some variables for consistency * fix pimoroni typos * Clamp instead of OR * Promote combined values to uint16_t * Update pointing_device.c Co-authored-by: Drashna Jaelre Co-authored-by: Nick Brassel --- docs/ChangeLog/20220226/PR15304.md | 13 + docs/feature_pointing_device.md | 116 +++++- docs/feature_split_keyboard.md | 8 + drivers/sensors/pimoroni_trackball.c | 22 +- drivers/sensors/pimoroni_trackball.h | 9 +- quantum/pointing_device.c | 389 +++++++++++++++++-- quantum/pointing_device.h | 13 + quantum/pointing_device_drivers.c | 22 +- quantum/split_common/transaction_id_define.h | 6 + quantum/split_common/transactions.c | 79 ++++ quantum/split_common/transport.h | 13 + 11 files changed, 625 insertions(+), 65 deletions(-) create mode 100644 docs/ChangeLog/20220226/PR15304.md diff --git a/docs/ChangeLog/20220226/PR15304.md b/docs/ChangeLog/20220226/PR15304.md new file mode 100644 index 0000000000..3cdb40db10 --- /dev/null +++ b/docs/ChangeLog/20220226/PR15304.md @@ -0,0 +1,13 @@ +### Split Common core now supports Pointing Devices ([#15304](https://github.com/qmk/qmk_firmware/pull/15304)) + +Pointing devices can now be shared across a split keyboard with support for a single pointing device or a pointing device on each side. + +This feature can be enabled with `#define SPLIT_POINTING_ENABLE` and one of the following options: + +| Setting | Description | +|---------------------------|------------------------------------| +|`POINTING_DEVICE_LEFT` | Pointing device on the left side | +|`POINTING_DEVICE_RIGHT` | Pointing device on the right side | +|`POINTING_DEVICE_COMBINED` | Pointing device on both sides | + +See the [Pointing Device](../feature_pointing_device.md) documentation for further configuration options. diff --git a/docs/feature_pointing_device.md b/docs/feature_pointing_device.md index 5aef9bea27..f8de92f3b4 100644 --- a/docs/feature_pointing_device.md +++ b/docs/feature_pointing_device.md @@ -127,11 +127,10 @@ The Pimoroni Trackball module is a I2C based breakout board with an RGB enable t | Setting | Description | Default | |-------------------------------------|------------------------------------------------------------------------------------|---------| |`PIMORONI_TRACKBALL_ADDRESS` | (Required) Sets the I2C Address for the Pimoroni Trackball. | `0x0A` | -|`PIMORONI_TRACKBALL_TIMEOUT` | (Optional) The timeout for i2c communication with the trackpad in milliseconds. | `100` | -|`PIMORONI_TRACKBALL_INTERVAL_MS` | (Optional) The update/read interval for the sensor in milliseconds. | `8` | +|`PIMORONI_TRACKBALL_TIMEOUT` | (Optional) The timeout for i2c communication with the trackball in milliseconds. | `100` | |`PIMORONI_TRACKBALL_SCALE` | (Optional) The multiplier used to generate reports from the sensor. | `5` | |`PIMORONI_TRACKBALL_DEBOUNCE_CYCLES` | (Optional) The number of scan cycles used for debouncing on the ball press. | `20` | -|`PIMORONI_TRACKBALL_ERROR_COUNT` | (Optional) Specifies the number of read/write errors until the sensor is disabled. | `10` | +|`PIMORONI_TRACKBALL_ERROR_COUNT` | (Optional) Specifies the number of read/write errors until the sensor is disabled. | `10` | ### PMW 3360 Sensor @@ -171,14 +170,35 @@ void pointing_device_driver_set_cpi(uint16_t cpi) {} ##
