Any ideas or examples? greetings, Jens EDIT: Ok, i was just to stupid to google. Found something! https://www.mikrocontroller.net/wik...

For the SD Card It seems to be a really straight forward design if you use SPI and the 3.3V Level of the STM32. Is it that easy?! just conn...

Bluepill as I2C Master and Slave

Sometimes a Raspberry will collect some data. (Sometimes in fact is 10ms ;) ) Currently i'm using a Raspberry pi 4 as an I2C...

Hey everybody :)

Hey everybody, my name is Jens and currently I'm working on a project in which I will use STM32 boards to control different sensor Modules and communicate with each other. The idea is to have a Master and some slaves. The slaves collect data from sensors and do some control work. The Master will col...
