Electronic, 3D printing and embedded programming
We are going to discover BNO055, a triaxial accelerometer, a triaxial gyroscope, and a triaxial geomagnetic sensor with a 32-bit cortex M0+ microcontroller in a single package.
In this first chapter, we start a basic usage.
We continue to explore the rp2040 devices, very interesting microcontrollers. All prototype boards come with integrated SPI Flash. Raspberry Pi selected the LittleFS filesystem to manage this storage, a good compromise between functionality and performance.
For devices like Arduino UNO, we can use the SPI Flash with a basic and very light library, but It can manage a good quantity of memory (from 256Kb to 64Mb), and it’s enough for a lot of projects.
SSD1306 IC is used for the most commons OLED display is a single-chip CMOS OLED/PLED driver with controller for organic / polymer light emitting diode dot-matrix graphic display system. It consists of 128 segments and 64 commons.
We are going to use it with SPI and i2c and learn the basic function.
