From 51b2d2fe6c554515c15b15ad528bd39da88ddbf1 Mon Sep 17 00:00:00 2001 From: Purdea Andrei Date: Sun, 25 Apr 2021 15:27:23 +0300 Subject: [PATCH] haptic: Feature to disable it when usb port is not configured or suspended. This also add support for specifying a LED pin to indicate haptic status, and also adds support for a haptic-enable pin, which is useful to turn off the boost converter on the solenoid driver. --- docs/feature_haptic_feedback.md | 11 +++++ drivers/haptic/solenoid.c | 16 +++++--- drivers/haptic/solenoid.h | 8 ++++ quantum/haptic.c | 51 ++++++++++++++++++++++-- quantum/haptic.h | 27 +++++++++++++ quantum/process_keycode/process_haptic.c | 3 +- tmk_core/protocol/usb_device_state.c | 10 ++++- 7 files changed, 115 insertions(+), 11 deletions(-) diff --git a/docs/feature_haptic_feedback.md b/docs/feature_haptic_feedback.md index 4054c5d9b743..159296a297e3 100644 --- a/docs/feature_haptic_feedback.md +++ b/docs/feature_haptic_feedback.md @@ -11,6 +11,16 @@ HAPTIC_DRIVER += DRV2605L HAPTIC_DRIVER += SOLENOID ``` +The following `config.h` settings are available for all types of haptic feedback: + +| Settings | Default | Description | +|--------------------------------------|---------------|---------------------------------------------------------------------------------------------------------------| +|`HAPTIC_ENABLE_PIN` | *Not defined* |Configures a pin to enable a boost converter for some haptic solution, often used with solenoid drivers. | +|`HAPTIC_ENABLE_PIN_ACTIVE_LOW` | *Not defined* |If defined then the haptic enable pin is active-low. | +|`HAPTIC_ENABLE_STATUS_LED` | *Not defined* |Configures a pin to reflect the current enabled/disabled status of haptic feedback. | +|`HAPTIC_ENABLE_STATUS_LED_ACTIVE_LOW` | *Not defined* |If defined then the haptic status led will be active-low. | +|`HAPTIC_OFF_IN_LOW_POWER` | `0` |If set to `1`, haptic feedback is disabled before the device is configured, and while the device is suspended. | + ## Known Supported Hardware | Name | Description | @@ -48,6 +58,7 @@ First you will need a build a circuit to drive the solenoid through a mosfet as | Settings | Default | Description | |----------------------------|----------------------|-------------------------------------------------------| |`SOLENOID_PIN` | *Not defined* |Configures the pin that the Solenoid is connected to. | +|`SOLENOID_PIN_ACTIVE_LOW` | *Not defined* |If defined then the solenoid trigger pin is active low.| |`SOLENOID_DEFAULT_DWELL` | `12` ms |Configures the default dwell time for the solenoid. | |`SOLENOID_MIN_DWELL` | `4` ms |Sets the lower limit for the dwell. | |`SOLENOID_MAX_DWELL` | `100` ms |Sets the upper limit for the dwell. | diff --git a/drivers/haptic/solenoid.c b/drivers/haptic/solenoid.c index 25cf344655b7..7a09940f78cb 100644 --- a/drivers/haptic/solenoid.c +++ b/drivers/haptic/solenoid.c @@ -19,6 +19,7 @@ #include "solenoid.h" #include "haptic.h" #include "gpio.h" +#include "usb_device_state.h" bool solenoid_on = false;
