    Basic p/ pll

    em Microcontroladores

    Postado

    olá amigos! A linguagem é Basic o compilador é o picbasic pro, esse codigo é p/  placa pll fm,o problema é o seguinte a frequencia escolhida no pic ,nao sintetiza com o saa1057,por favor alguem sabe dizer onde esta o erro. o codigo completo é esse:
