@felmue Do you have an idea what the lowest (device still working) voltage is and what the maximum is? It's a 3.7V battery? But I think when it's fully charged it can be 4.2V? I've tried to find something of a table to convert voltage to % power left, but failed to find anything useful. In example code that I saw, they used something like 3.3V as lowest possible voltage, but my initial test told me that it craps out around 3.8V / 3.7V?

Or are the measurements that you get from the api just not worth while to use?

@ajb2k3 said in Micropython - SHT30 in BTC Base:

Micropython on the M5Paper is in early alpha because we pushed M5Stack to get it out before the holiday. I spent yesterday doing some testing and I cannot get any SHT30 devices to work no matter if its the internal SHT30 on the paper or the env2 unit.
What lib are you using as I cant even get raw reg read and writes to work.

For now I have abandoned micro python and switched to (yuck) C and platformio.

@lukasmaximus Why is it still not fixed?

I honestly don't understand M5Stack's way of working. There is this ENV2 with python support: https://docs.m5stack.com/#/en/unit/envII it has a SHT30, but then you spend $80 on a M5Paper and you don't get python support for the SHT30. How hard is it to put in the the right lib.

I know I can do it myself, but M5stack should have done this already :-/

I know the documentation says that the RFID face uses i2c to communicate with the core-module, but could I also use SPI? Are those pins also connected (the RC522 RFID chip supports both)?

The project that I would like to use currently only supports SPI and not i2c.
