Hi,

I don't understand why on pin PB.1 still I get signal (checked with osciloscope), shouldn't be pin PB.1 low instead of high so far?
here my code:
[code]
'ARDUINO PRO MINI 3.3V
'Bootloader zaktualizowany do optiboot (jak UNO) w wersji dla uC zasilanych 3.3V
$regfile = "m328pdef.dat"
$crystal = 8000000
$baud = 9600
$hwstack = 100
$swstack = 100
$framesize = 100

'Config Portb.1 = Output : Led1 Alias PORTb.1 : reset Led1 'OC1A
Config Timer1 = Timer, Compare_A = disconnect, Compare_B = clear, Prescale = 256, clear_timer=1
Config int0 = Low Level
compare1a=15000

On compare1a gen1
enable compare1a
Enable Interrupts
gen1:
Return
[/code]
Regards,
Martin

First of all maybe you need a "Do : Loop : End" Without it program will reach end of flash and start from the begining.

Hi,
Of course you're absolutely right, I even did it before (and it looked that it didn't help, and I wondered what the hell...).
What a ridiculous mistake I made! I updated and still changed the code, but with the persistence of a maniac I uploaded another .hex file, haha!
