Simple RTOS, low-end ATmega microcontrollers oriented
This project designed for ATmega16/48/88.
the key properties:
+only assembler language
+small code size
+fast context switching
+up to 8 user task
+one timer for each task
+up to 16 events
on/of dynamical buffers system (sorry, very slow ~40 clock read/write)
for on-board UART separate RX and TX task.
