Sotva jsem začal, mělo by to negovat porty, nějak nevim, co víc už nastavit a hlavně to proběhne a pak přestane. I když hodnota j na lcd roste. Nevim, jestli se nastavuje ještě někde něco, jak řikam, tak začínam ... Budu rád za jakékoliv doporučení (prostředí (AVR Studio, CodeVision, ...), osvědčené tutorialy, ...)
