STM32 - Cortex M4 - #5 i2c+dma

When communication with other devices (usually slower ones) the DMA offers the advantage of relieving the microcontroller from the cumbersome task of controlling the peripherals, copying bytes or waiting for communication events. Here I have a classical example where I want to use the

Rotary encoder for STM32

A rotary encoder is one of the easiest way to get simple users interaction with the microcontroller. I would like to include this into one of my future projects and because of this I made a simple library based on RTOS events and interrupts.

Projects

ST-Link Bridge - I2C EEPROM

A small application to read and write eeproms (e.g. AT24C04) using the ST-Link Bridge functionality. This is quite useful for projects using additional eeprom memory that needs to be checked out.

STM32 - Cortex M4 - #3 adc

The ADC allows a the application to read analog voltages using a single ADC from a maximum of 16 external sources with maximum 12 bit resolution. Clock (digital part) Getting

STM32 - Cortex M4 - #2 oled

Since some time now I have a couple of very old OLED displays - 128x128 pixels. These are driven by the ssd1339 chip for which I found the datasheet online.

Microcontrollers

STM32 - Cortex M4 - #1 blink

Since the Cortex M4 offers some clear advantages and improvements over the M3 I started working on this as a side project. The goal is to make this a feasible

A repeating signal... DCF77

After some discussions with the colleagues I was intrigued about how the DCF77 Signal is encoded and how hard it would be to practically decode this. So as any other
