MicroPython

Working with sensors creates quite a few libraries. Some are written by me, others are adapted and even more are just used.

Examples

Example code for interfacing the Raspberrypi Pico

• Motors Control motors with the Raspberry Pi Pico
• Internal Temperature Sensor Read the internal temperature sensor with a loop!

Tips and Tricks

Tips and tricks explaining some coding concepts or useful tools within the micropython ecosystem.

• Threading Threading on the Raspberrypi Pico. Allowing two while loops running at the same time!
• WatchDog Use the watchdog which reboots the Pico when something doesn't work!

Libraries

In the libraries subfolder there are submodules with my own modules. Here is a list of both my own code, drivers adapted from others code or links to drivers written by others.

Acceleration

• LIS3DHTR Driver for the Grove - 3-Axis acceleromter for the Rasbperry Pi Pico.
• MSA301 Library for the Adafruit MSA301 accelerometer. I had to change the device address (from 0x26 into 0x62, else it did not work).

DAC (digital to analogue converter)

• MCP4725 Driver for the DAC MCP4725 DAC. Based on work from Wayoda.

Display

• SSD1306 Driver for the SSD1306 screens (works also with SSD1315).

Environment

• SPS30 Driver for the particulate matter sensor SPS30 for the Raspberry Pi Pico.
• SEN6x Driver for the environment sensor SEN66 and SEN63-C for the Raspberry Pi Pico.
• SGP30 Example code for interfacing the SGP30 VOC and eCO2 sensor.
• SGP40 Example code for interfacing the SGP40 VOC sensor.

Light

• LTR390 Driver for the Ambient and UV light sensor LTR390 from Adafruit.
• AS7341 example code for the 10 band optical light sensor for measureing different colours.

Location

• VL53L4CD Example code for the range (0-20cm) sensor.

Magnetic Fields

• TLV493D Driver for the magnetometer TLV493D, based on the work from Adafruit and Maarten Doves.

Temperature and/or humidity or pressure

• SHT4x Driver for the SHT4x Temperature and Humidity sensors. A bit outdated, but does still work.
• BME680 example code for the BME680 temperature, humidity and pressure sensor.

MicroBIT platform

Robots

• CutebotPro MicroPython library for the CutebotPro with a Micro:bit running MicroPython.

Git Submodules

If you want all submodules when this repository is cloned use

git clone --recurse-submodules

All data from the submodules will be pulled to their respective directories.
