ESP32: Integrate SCD30 Sensor Library #175

Closed keenanjohnson closed 1 year ago

keenanjohnson commented 1 year ago

As part of the effort to create an EPS32 based Golioth Frog Sensor https://github.com/Ribbit-Network/ribbit-network-frog-sensor/issues/126 , we need to find and integrate drivers for the Frog Sensors into the ESP-IDF framework stared in this branch: (https://github.com/Ribbit-Network/ribbit-network-frog-sensor/tree/esp32_golioth)

Sensors SCD-30 - NDIR CO2 Temperature and Humidity Sensor - https://www.adafruit.com/product/4867

There's a common set of sensor drivers UncleRus/esp-idf-lib which has support for the SCD-30.

keenanjohnson commented 1 year ago

There is an example project here showing how to integrate the SCD-30 library

https://github.com/UncleRus/esp-idf-lib/tree/master/examples/scd30/default

keenanjohnson commented 1 year ago

The basic proof of concept code is now complete for reading data from the SCD30 sensor. Will validate with hardware shortly.

I'm attempting to test this with the hardware and discovered that the Adafruit dev board we are using has a switchable power source for the I2C connector that gets disabled when I flash the board.

I'm trying to set the pin controlling that power source to high, but I can't seem to make it work. Perhaps you have some insight into what I might be doing incorrectly @beriberikix?

beriberikix commented 1 year ago

Oooh, I didn't know they added that. Very useful for future battery readings as well as low-power mode. I think there's a bit of initialization missing, which is probably masked by scd30 library. Fortunately there's also a library for the battery gauge that will be useful for future features, not just enabling: https://esp-idf-lib.readthedocs.io/en/latest/groups/lc709203f.html

I would suggest breaking this up a bit further - just getting each one of the I2C devices working in a standalone example, integrate them one at a time and then add Golioth.

If that fails, or just because, hop over to our forum :)

keenanjohnson commented 1 year ago

I tried flashing a few more times and I actually believe this is an issue with the debugger not resetting the esp32 properly after the flash. When I manually power cycle after the flash, this works as expected. Will need to investigate more.

beriberikix commented 1 year ago

Ah yes, that's one annoying thing about the ESP32 Feathers - you have to put it in "programming mode"...sometimes. Have you put it into bootloader mode https://learn.adafruit.com/adafruit-esp32-s2-feather/factory-reset#step-2-enter-rom-bootloader-mode-3106832 ?

Yes, that’s the way I get it to flash most of the time unfortunately. Is that why I have to manually power cycle after to get it out of programming mode at the boot loader level?

Any work around a or documentation that better explains the interactions between the boot loader, esp-idf and everything I should read?

Nevermind, after reading the adafruit docs on this board, the behavior is quite clear.

I have a consistent process to flash using the reset button, however, I believe I have two separate problems.

  1. The scd30 code from the example in doesn't seem to function. I have filed an issue to get to the bottom of that here: https://github.com/UncleRus/esp-idf-lib/issues/464
  2. I'm having some problems setting the golioth nvm wifi credentials using the terminal program.

I get this error from the terminal and no commands seem to produce any change or output in the terminal.

Press Enter or Ctrl+C will terminate the console environment.

Your terminal application does not support escape sequences.

On Windows, try using Putty instead.

keenanjohnson commented 1 year ago

I've completed this task.

I have created an esp-idf project that integrates the SCD30 library and the latest golioth firmware from https://github.com/golioth/golioth-firmware-sdk

I have validated that the code does talk to the SCD30, connects to golioth, etc
