Zdar,

nemohl byste mi nekdo poslat konfiguraci registru tak, aby to bylo schopne prijimat a vysilat na USART1...Rx na RC7 a Tx na RC6.

Docilil jsem toho, ze to vysila tak jak jsem zvyklej, ale cokoli tam poslu tak zmizi v cerny dire.

Nez zacnu pitvat ASM z prekladace tak bych docela rad vedel zda tam nemam nejakou principialni botu v nastaveni tech vsech vopicaren.

Dalsi vec je, ze tahle rada je poprve v kompileru podporovana a tak jen doufam, ze tam nemaji nejakou botu.
