| Interrupt based button read on STM32F103ZET6 board |
| 2011-11-13 18:34:00 |
In previous example we implemented a simple demo program that reads buttons by constantly checking their status in main program loop. Obviously this isn’t efficient and convenient way to do that. Imagine your program has to do lots of tasks … Continue reading →...

| FreeRTOS on AVR with external RAM |
| 2011-08-31 15:39:23 |
AVR microcontrollers aren’t best choice to run FreeRTOS scheduler due to low RAM. Atmega128 has only 4K of RAM memory, so this limits FreeRTOS functionality to very basic. Anyway this can be solved by adding extra RAM connected to external … Continue reading →...
