Stm32f103 course
Hello! Update, the course is completed and can be found on udemy, link is here: STM32 Beginner Course I’ve seen some interest in my stm32 blinky example tutorial and want to give you guys more content in the fun embedded world, especially for the stm32 microcontroller. I’ve put up a table of contents down below,…
STLink server on a Linux server
I’m currently doing a project with STM32 and radios. I want to have a server with all the stm32’s connected, with UART, USB and ST-Link v2. I’m using a laptop as my development computer and don’t want to plug the connections in and out all the time. Therefor I installed a Linux server which will…

mMesh – Mesh Network
I have created a mesh network algorithm for embedded systems. This implementation is released be released under MIT License. Me and a friend have started an Internet Of Things project and we wanted to have a radio module to our microcontroller for communication. The radio module we choose was the NRF24L01+. One question might arise:…
Updating Espressobin U-boot via tftp.
To update u-boot via tftp, install a tftp software and copy its binaries to the directory where tftp has its data. The text in bold is the text you type in. This is intended for armbian use. They require the latest u-boot version.

Steg 2: Bygga högtalarlåda
Höjdens maximala yttermått var 57 cm varav lådan byggdes med den höjden. Fick rekommendation av hifikit att bredden skulle vara smal, varav frampanelen gjordes med en bredd på 24 cm. Djupets storlek räknades ut enligt nedan:
