Playing with the Ikea ALPSTUGA SEN63C sensor (I2C)

[Massimo]

I bought a couple of ALPSTUGA air quality monitors, one to be used normally and the other to play with the sensor (Sensirion SEN63C-SIN-T https://sensirion.com/products/catalog/SEN63C) which being I2C can be interfaced to RC2014.

Once again I got Claude to write an application (two really, one for bit-banged I2C and the other for PCF8584 modules) to read its data and perform few other operations:

Interfacing it was relatively easy, but I had to cut the cable and crimp standard DuPont connectors to make an adapter.

Also I made a little board with a 3.3V regulator module (SDA and SCS on the other hand are 5V TTL tolerant) for convenience.

I'm attaching the binaries and the sources which are a bit of a general restructuring of the I2C drivers and not monolithic asm files with everything inside
