Enhancement/ads1x15 integration by oscgonfer · Pull Request #7404 · meshtastic/firmware

oscgonfer · 2025-07-21T12:09:55Z

This is a Pull request for the TI ADS1X15 series. This is replacement of the wrongly closed (by myself, I don't know how) #7109.

PRs for the protobufs are already merged. I have tested this already with two different setups:

ADS1X15 board by adafruit (powered at 3V3), with and without daisy chaining.
Analog sensor board (https://docs.smartcitizen.me/hardware/boards/analog-sensor-board/) which has two ADCs, a step-up on the voltage, and a level-shifter made out with mosfets. This I2C bus is a bit dirtier, and can't work at high speed, so the same change applied on the SEN5X PR (Feat/add sen5x #7245) is applied here.

We have two perhapsSetRTC functions, which are called to set the time. The one with 3 parameters had a helpful check to reject an invalid time, by comparing the time from the source against when the firmware was compiled. The one with 2 parameters, which is called from the GPS lookForTime did not. As a result, certain GPS with bad time handling could set a time that was in the past. This patch adds the same epoch check code to the other perhapsSetRTC method. Fixes meshtastic#7364

This fixes daisy chaining of various sensors together, with a "dirty" I2C. I2C buses with step-ups and with level-shifters with mosfets can have issues at high speeds.
