Hello fellow freaks,
I am working on a simple remote control, which should use the sleep instruction. After a interrupt, it should wake up, send some code via IR, return from the interrupt and enter sleep-mode again.
Somehow, my attiny15 does not seem to wake up after a external irq. Anyone had this problem before or does seem familiar to?
Thanks in advance and a happy new year for now!
structure program is kinda like this:
setup mcu for power down mode, but do not enable the sleep mode
setup all other stuff for mcu
go to sleep
delay of 512 ms
rjmp to begin main program
