with the flexibility that the Raspberry Pi provides and the staggering number of possible pin combinations, there are definitely cases where it fails to detect it properly. This is why we wrote the Python Extended Bus library, which allows you to specify the bus and device ID so you can tell...

Pro Tip: If you are interested in using Python, you’ll need to install python-smbus first. Once we have a basic understanding of how to program for I2C from looking at examples and documentation, we need to dive into the specifics of our sensor using the MPL3115A2 datasheet. Luckily,...
It will take you a bit of effort to convert it to Python, as they use pioasm both to create the main PIO program and to build a table of instructions that the program later feeds into the Tx FIFO, but it's not a very big table and you could build it by hand (just make an arr...
This Python code is about a i2c -D/A &A/D- device, PCF8591 library using wiring pi on Rasbperry pi 3. Plese feel free to use ! - ShuDiamonds/PCF8591
