I2C Communications between Raspberry Pi and Arduino – Update
Over the past few days, I have been able to bit bang the I2C bus with the PIGPIO library. I found a very helpful example at http://raspberrypi.stackexchange.com/questions/3627/is-there-an-i2c-library/4052 which was posted by crj11. This example was using the pigpiod_if.h library. This worked well but required the application to be run with elevated privileges (sudo) which was not acceptable…
I2C Communications between Raspberry Pi and Arduino – Update, BOM, and Source Control
Update I have been working on this project over the past couple of weeks when I have free time but have not been posting updates. This is a general update which is why the title is different from the other posts regarding this project. My boards from OSH Park arrived last week. I was able to…
I2C Communications between Raspberry Pi and Arduino – Part Four
It has been two weeks since my last post but it has been out of frustration on porting the code over to the ATtiny85. The first thing that I ran into was that the Wire library is not supported on the ATtiny85. I needed to modify my code to work with the TinyWireS library. This…
I2C Communications between Raspberry Pi and Arduino – Part Three
Today’s goal is to send a string from the Arduino to the Raspberry Pi. The setup is the same as from day two. After several attempts and stupid mistakes, I was finally able to get a “Hello World” message from the Arduino to the Raspberry Pi. Here is the code for the Arduino #include <Wire.h>…
I2C Communications between Raspberry Pi and Arduino – Part Two
The goal of the day is to get the Raspberry Pi and Arduino talking to each other over I2C. I followed a few examples provided on the internet and was able to get the two to talk to each other. Just to be clear, the Raspberry Pi will be the I2C master and the Arduino…
I2C Communications between Raspberry Pi and Arduino – Part One
My daughter has a science project for school on bread mold growth. She will need to monitor the temperature, humidity, and light level of 3 separate environments. Being the geeky dad that I am, I decided to make her some data loggers to monitor each environment. I would also like to take this further by…
