software Extreme Burner , com gravador USBASP
Fuses: E4 99
Calibrated internal RC Oscillator/
CKSEL0 =0
CKSEL1 =0
CKSEL2 =1
CKSEL3 =0
Mas o problema eo seguinte quando gravo o programa feito no codevision, vou testar o PC3,Pc4, Pc5 ,PC2 não assumem o valoresde saida ou seja um simples pisca led não funciona as saidas parecem que fica em alta impedancia pois o led fica aceso com um brilho fraco, olhando um site verifiquei que para ter o pleno funcionamento do portc devo desabilitar o JTAG http://www.engineersgarage.com/embedded/avr-microcontroller-projects/disable-jtag-port esta opção está correta em desabilitar o jtag para o portc funcionar corretamente, se desabilitar o jtag o avr não ira mais gravar ...por favor me ajudem vou postar o programa abaixo da ultima tentativa para fazer o portc funcionar.
