IR controlled 32-bit Cortex-M3 blinking Christmas Tree using EFM32

Before Christmas and the last EFM32 hacking event in 2012, the mission was to introduce as many as possible to the joy of soldering and electronics here at Energy Micro. Even though the blinking x-mas tree electronic kit has been done countless times before, we decided to do an EFM32 version as well. After all, it is Christmas time and nothing is more suitable than blinking LED’s when it comes to learning electronics and soldering. The one and only 32-bit Cortex-M3 driven Christmas Tree from Energy Micro with IR and touch interface, 12 Bi-color LEDs for multiple colors and slide-together-kit-PCB.
