BNO08x – 9-DoF-IMUs

The BNO08x family comprises 9-DoF IMUs that use sensor fusion to detect orientation in space and complex movement patterns such as footsteps. I will show you how to control these sensors with suitable libraries.

STM32 boards – Part 2: Selected functions

I will show you how to implement selected functions on STM32 boards using the Arduino Core package. I will cover timers, PWM, low power, I2C, SPI, ADC, DAC, RTC and more.

DS3231-based alarm clock

I present concepts for a DS3231-based alarm clock. The alarm clock is controlled with only two buttons and a slide switch. I use the Nokia 5110 and the DOGS164 as energy-saving displays.

TinyWireM vs. Wire for ATtinys

To save valuable flash memory on ATtinys when using I2C, you can use alternatives to Wire.h such as TinyWireM. I show how it works.

EEPROM Part 2 – external I2C EEPROMs

I show how you can use I2C controlled EEPROM ICs with your microcontroller. This works very comfortably with a library, but it can also be done without it.

Logic Analyzer

The Logic Analyzer is a low-cost tool that allows you to analyze signals such as I2C, SPI, PWM and much more. I introduce the Analyzer and the Logic 2 software.
