rezistor · 2006-08-30T02:16:04.0000000+03:00

arkadaşlar avr-gcc de yazılan programları burada toplayabilirmiyiz.. eğer program yazan varsa buraya eklesin lütfen ben yakında denenmiş bir lcd programı eklicem....... denenmiş veya denenmemiş diyede yazarsanız iyi olur.. teşekkürler.......

programı denedim çalışıyor fakat LCDWrite() fonksiyonuna integer tipte değişken gönderilmiyor
önce integer dan string e çevirmek gerekiyor böyle bir fonksiyon bilen arkadaş varsa foruma eklerse sevinirim...
teşekkürler...
