#Preemptive Scheduler
Simple PoC Pre-emptive scheduler for an Atmel atMega168a Pre-emption code based this tutorial: http://kevincuzner.com/2015/12/31/writing-a-preemptive-task-scheduler-for-avr/
#Display Shield Custom shield with 2 LEDS and 2 7-Segent Displays driven by HEF4543B BCD-to-7Seg Drivers.
Logic 1 Illuminates LED1 = PORTB1 LED0 = PORTB0
BCD Common address bus = PORTD7-4 BCD LatchEn MSD = PORTD3 BCD LatchEn LSD = PORTD2
#Attaching to simulator Run avr-gdb Then run:
- file preempt-sched.elf
- target remote localhost:8282
- load
- break main
- continue
#Introducting Delays Run 'make clean all PFLAGS=-DGREEDY_TASK' to add delays into a task to demonstrate benefits of a preemptive system.
