Прошу Вашей помощи. Грабанули квартиру теперь срочно делаю сигнализацию Здравствуйте Прошу Вашей помощи. Грабанули квартиру теперь срочно делаю сигнализацию. Точнее переделываю проект Леонида Ивановича (http://www.telesys …ts/proj054/index.shtml) на далласе. После походов по милиции голова не варит никак не могу сделать следующее кнопка open используется в качестве охранного шлейфа. далассом производитсяф постановка и снятие с охраны при этом издается короткий сигнал (solen=0) а при разрыве в режиме охраны включается сирена на постоянно, но хочу переделать чтобы минут на 20 вкл сирена потом 10 минут перерыв и снова на 10-15 минут включилась (т.е. 2 раза с перерывом) далее если двери закрыли берется снова под охрану если нет оснается отключенной до новой постановки ключем даллас. но как сделать не веду после нервотрепки. Помогите пожалуйста. пологаю что надо так но что то не получается trevTMV .EQU 60 000 ;x20mS задержка 20 минут . . . . ;=====MY TREVOGA===== TREVOGA: JB OXPAHA,ONBIP SETB SOLEN JNB OXPAHA,OFFBIP ONBIP: CLR SOLEN OFFBIP: mov trevTM,#trevTMV RET ..... ...
