Simple LED matrix alarmclock with temperature measuring

This project is a simple LED matrix clock. It can use either MAX7219 as LED drivers (one IC per matrix) either HT1632 LED driver. It's possible to use 3 or 4 matrixes, but recent code is more suitable for second option.

While project uses various parameters from EEPROM memory special desktop application to edit eeprom matrixclock_xx.bin was designed. It allows to load, modify and save eeprom binary file in easy way.

Matrixclock editor is written on Qt5 and it's sources are availiable on Github.
