    تنظیم ابعاد صفحه نمایشگر tft

    سلام
    دوستان توی نت چند برنامه مربوط به نمایش ساعت و دما رطوبت پیدا کردم روی اردوینو پروگرام کردم چون برنامه مربوط به نمایشگر های 3.9 بود نمایشگر من 2.4
    متن ها خیلی بزرگ بود از صفحه نمایش میزد بیرون
    کدس برنامه
    کد:
    // original sketch from http://educ8s.tv/arduino-real-time-clock/
    // Nicu FLORICA (niq_ro) from http://www.arduinotehniq.com 
    // made some chenages for animate display with blinking signs
    // eliminate library for clock, use just subroutines
    // use 3 buttons for manual adjust the data & clock
    // add alarm (now usee eeprom memory for store hour alarm)
