Update (#10)

* (1/3) Support L76B GNSS chip found on pico waveshare shield. Original work by @Mictronics * NodeInfo broadcast ensure default on 0 and enforce 1 hour minimum (meshtastic#3415) * NodeInfo broadcasts ensure defaults on 0 and enforce 1 hour minumum * Doh! * Hey that's not on config! * We don't use Lorawan (meshtastic#3417) #warning "Persistent storage not supported!" [-Wcpp] * [create-pull-request] automated change (meshtastic#3418) Co-authored-by: thebentern <[email protected]> * fix compilation * don't fix this to a hardware model. * new Accelerometer lib (meshtastic#3413) * new Accelerometer lib * Use our fork till upstreasm merges changes. * that PR escalated quickly * resurrect display flip * that should work now * (2/3) Add Slow Clock Support for RP2040 platform. This will disable USB Softserial. * More comprehensive client proxy queue guards (meshtastic#3414) * More comprehensive MQTT thread and queue guards * Consolidate logic * Remove channel check * Check for map_reporting_enabled as well * Update message * Remove channel check from here as well * One liner * Start the mqtt thread back up when channels change and we want mqtt * fix for I2C scan getting stuck (meshtastic#3375) * refactor: add delay for T-Echo peripherals setup * comment out `PIN_POWER_EN1` * [create-pull-request] automated change (meshtastic#3419) Co-authored-by: thebentern <[email protected]> * Handle for heartbeat toradio packets (meshtastic#3420) * Factory reset GNSS_MODEL_MTK GPS modules with PCAS10,3 (meshtastic#3388) Co-authored-by: Ben Meadors <[email protected]> * [create-pull-request] automated change (meshtastic#3422) Co-authored-by: thebentern <[email protected]> * (3/3) Add variant for pico with waveshare and GPS hat (meshtastic#3412) * (3/3) Add variant for pico with waveshare and GPS hat, utilizing slow clock. * Not everybody has Serial2 * Trunk * Push it real gud * No init --------- Co-authored-by: Ben Meadors <[email protected]> --------- Co-authored-by: Thomas Göttgens <[email protected]> Co-authored-by: Ben Meadors <[email protected]> Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> Co-authored-by: thebentern <[email protected]> Co-authored-by: Andre K <[email protected]> Co-authored-by: David Ellefsen <[email protected]>
