From f4a2023dbad5e50ca6e0d4aa197a9bf92fb78041 Mon Sep 17 00:00:00 2001 From: Gareth Coleman <30833824+garethhcoleman@users.noreply.github.com> Date: Fri, 12 Apr 2024 01:40:14 +0100 Subject: [PATCH] LSM6DS3TR-C support (#3593) * started work on pulling in the unphone library and dependencies, to do e.g. power switch management and etc.; currently failing at Adafruit_ImageReader * now compiles with unphoneLibrary included * successfully pulled in unphone library to manage power switch and init vibe motor and etc. doesnt print to serial tho... * simplified the build a bit; when doing meshtastic do not depend on the MCCI lora libs etc., then also no need to config them via build flags * version that doesnt trigger brownout * cleaned up initVariant a little * note re. GPS * back to mesh upstream version * this time we're back to mesh upstream version * getting LSM6DS3TRC driver installed * shake to wake works, set threshold quite low may need increasing * whats the crack with these end of file changes? * paramatize the wake threshold * try to get the PR to just include real changes * got the right config item and also not giving compiler messages * moved the lib_deps for the LSM6DS3TRC driver from our variant platformio.ini to the main one in root so all boards have it * stuupid error #define-ing --------- Co-authored-by: Hamish Cunningham Co-authored-by: Ben Meadors --- platformio.ini | 1 + src/AccelerometerThread.h | 16 +++++++++++++++- src/configuration.h | 3 ++- src/detect/ScanI2C.cpp | 4 ++-- src/detect/ScanI2C.h | 1 + src/detect/ScanI2CTwoWire.cpp | 1 + variants/unphone/variant.h | 2 ++ 7 files changed, 24 insertions(+), 4 deletions(-) diff --git a/platformio.ini b/platformio.ini index 2c373ab00..d54a06d3e 100644 --- a/platformio.ini +++ b/platformio.ini @@ -132,3 +132,4 @@ lib_deps = adafruit/Adafruit MPU6050@^2.2.4 adafruit/Adafruit LIS3DH@^1.2.4 https://github.com/lewisxhe/SensorLib#27fd0f721e20cd09e1f81383f0ba58a54fe84a17 + adafruit/Adafruit LSM6DS@^4.7.2 \ No newline at end of file diff --git a/src/AccelerometerThread.h b/src/AccelerometerThread.h index 6827908b7..fa5acdaae 100644 --- a/src/AccelerometerThread.h +++ b/src/AccelerometerThread.h @@ -5,6 +5,7 @@ #include "power.h" #include +#include #include #include #include @@ -108,6 +109,15 @@ class AccelerometerThread : public concurrency::OSThread bmaSensor.enableTiltIRQ(); // It corresponds to isDoubleClick interrupt bmaSensor.enableWakeupIRQ(); + } else if (acceleremoter_type == ScanI2C::DeviceType::LSM6DS3 && lsm.begin_I2C(accelerometer_found.address)) { + LOG_DEBUG("LSM6DS3 initializing\n"); + // Default threshold of 2G, less sensitive options are 4, 8 or 16G + lsm.setAccelRange(LSM6DS_ACCEL_RANGE_2_G); +#ifndef LSM6DS3_WAKE_THRESH +#define LSM6DS3_WAKE_THRESH 20 +#endif + lsm.enableWakeup(config.display.wake_on_tap_or_motion, 1, LSM6DS3_WAKE_THRESH); + // Duration is number of occurances needed to trigger, higher threshold is less sensitive } } @@ -133,6 +143,9 @@ class AccelerometerThread : public concurrency::OSThread wakeScreen(); return 500; } + } else if (acceleremoter_type == ScanI2C::DeviceType::LSM6DS3 && lsm.shake()) { + wakeScreen(); + return 500; } return ACCELEROMETER_CHECK_INTERVAL_MS; @@ -156,6 +169,7 @@ class AccelerometerThread : public concurrency::OSThread ScanI2C::DeviceType acceleremoter_type; Adafruit_MPU6050 mpu; Adafruit_LIS3DH lis; + Adafruit_LSM6DS3TRC lsm; }; -} // namespace concurrency +} // namespace concurrency \ No newline at end of file diff --git a/src/configuration.h b/src/configuration.h index 7ce1a0b8b..66ec607ff 100644 --- a/src/configuration.h +++ b/src/configuration.h @@ -128,6 +128,7 @@ along with this program.
