Ushbu dastur ATmega32 uchun yozilgan

Bu bir nechta qurilmalarni ATmega8535 uController-ga ulash uchun mo'ljallangan ko'p maqsadli dastur

Interfeys TWI, UART va parallel aloqa avtobuslari yordamida amalga oshiriladi.

Qo'llab-quvvatlanadigan qurilmalar:

DS1624 Temp sensori

DS1307 RTC

HD44780 mos keladigan LCD

O'rnatilgan veb-server sayti

Tuzatish tarixi:

1.00 boshlang'ich versiyasi

1.01 qo'shilgan LCD qo'llab-quvvatlash

1.02 Siteplayer-ga qo'shilgan

1.03 qo'shilgan DS1624 qo'llab-quvvatlash

1.04 DS1307 qo'llab-quvvatladi

1.05 TWI interupt asosida amalga oshirildi

1.06 Interupt Driven 4x3 klaviaturasi amalga oshirildi

1.07 Termostatni boshqarish vositalari amalga oshirildi

LCD displeyi HD44780 bilan mos keladi
