commit 398a2ce Author: robotmad <[email protected]> Date: Tue Sep 15 21:25:59 2026 +0100 use TILDAGON_XXX_I2C_PORT definitions in place of magic numbers for I2C mux ports commit 83e1411 Author: robotmad <[email protected]> Date: Tue Sep 15 21:25:32 2026 +0100 GPIO pins via AW9523B: cache output state, direction and mode in RAM. Use tildagon-i2c-manager one-shot C callback job for the last write of any action so that micropython can return and leave that to take place in parallel. FreeRTOS Semaphore used to mange serialisation of I2C access for maximum performance. Move toggle to C layer to take advantage of caching. Update fakes for Pin and ePin. commit ffc479b Author: robotmad <[email protected]> Date: Tue Sep 15 21:23:27 2026 +0100 Frontboard 2026 compass - use tildagon-i2c-manager job for polling. The job only does data transfer - so conversion from raw bytes to meaningful values moved to the read function. commit 78da35e Author: robotmad <[email protected]> Date: Tue Sep 15 21:22:28 2026 +0100 IMU class:: use of tildagon-i2c-manager jobs for I2C polling. get and set_period() methods. Default to sensor I2C polling being Off - automatically activated on first read at 'legacy' rates 40mS for gyro/accelerometer, 1000mS for temperature and steps (now controlled separately from accel/gyro). Uses refactored BMI270 driver. Use of const to reduce RAM use. New tildagon_imu_state_t structure for RAM so that lsm6ds3 and bmi270 don't have duplicate static allocations internally. lsm6ds3 control register set to filter sensor data in sync wtih the intended I2C read poll rate. commit a78d22c Author: robotmad <[email protected]> Date: Tue Sep 15 21:21:32 2026 +0100 support 16 bit addressing of i2c device registers (e.g. SCD4X) commit 5ee12dc Author: robotmad <[email protected]> Date: Tue Sep 15 21:14:29 2026 +0100 tildagon_i2c_manager: new task in place of imu task, supports i2c operations running in parallel wtih micropython for imu, but also any other i2c transaction can now take advantage of this parallelism via C callbacks for C/micropython 'jobs'. micropython API provided for 'jobs' comprising up to 5 steps. READ/WRITE/READ16/WRITE16/CHECK step types. One-Shot (run_once) or Periodic execution with status monitoring and optional 'Pin.irq' style callback upon completion. Support for I2C devices with 8 bit and 16 bit register addressing. 10 slots for I2C callbacks/jobs. Replace extern ad-hoc declarations. commit 9c3948f Author: robotmad <[email protected]> Date: Tue Sep 15 21:01:48 2026 +0100 IMU - refactored minimal bmi270 driver in place of flow3r one, with support for setting read/update period and hence internal filters to match I2C polling period. commit f10ecb8 Author: Sam Machin <[email protected]> Date: Mon Sep 14 22:51:16 2026 +0100 Feat/utc settings (emfcamp#440) * add utc offset to settings * add utc offset to settings * store seconds use offset as label * fix formating commit 1fe0fad Author: Sam Machin <[email protected]> Date: Mon Sep 14 22:21:36 2026 +0100 keyboard enter done in TextDialog (emfcamp#443) Allows the enter key to trigger Done in a TextDialog commit f2f6a3d Author: Matthew Wilkes <[email protected]> Date: Mon Sep 14 22:19:22 2026 +0100 Add RMT RX peripheral (emfcamp#425) Backports micropython/micropython#18454 from MP 1.29 (or later) commit 9b833f0 Author: Sam Machin <[email protected]> Date: Mon Sep 14 21:28:10 2026 +0100 add ntpsync service (emfcamp#442) commit ee80b27 Author: Christopher Barnes <[email protected]> Date: Mon Sep 14 20:19:09 2026 +0100 Change FreeRTOS tick rate to 1mS (emfcamp#456)

Force ESP-IDF to use 1mS (i.e. 1000Hz) for FreeRTOS tick period. As long as calls to vTaskDelay() use the macro pd_MS_TO_TICKS (or equivalent) then the delay will be the same, subject to finer resolution being possible. There are times where delays are implicit due waiting for to FreeRTOS task switching - code that depends on these currently delivering 10mS latency could be affected by the faster rate, but should be OK as even 1mS is quite long in electronics terms.
