Environmental Sensors
In August 4, 2019 I built a circuit using a TMP117 temperature sensor, Si7021 Humidity sensor, and SGP30 Air Quality sensor. It displays the data on a 16x2 LCD display. The microcontroller used here is an MSP430G2553.
I never posted the source code because it didn't seem that useful to others. The code itself is written in assembly and I ended up using a software i2c instead of the built-in hardware. I've recently received emails asking for the source, so here it is.
To build it, it requires naken_asm and the Makefile will need to be modified for your environment (just the path to the include files).
