]Olá pessoal, estou com um problema em um projeto que esta a quase uma semana me atrasando, é o seguinte, eu preciso usar uma interrepção externa para que de tempo em tempo o PIC18F4550 envie a temperaturas lidas, esse bloco da leitura das temperaturas tem que ser em uma interrepção externa para nao atrapalhar no restante da função principal MAIN, o problema é que eu implementei o TIMER 0 como o fabricante do compilador diz, com toda a sintaxe correta(eu acho) e mesmo assim a interrpução nao ocorre, nao enviando os dados. Eu nao consigo mesmo achar o que esta de errado na implementação, por favor se alguem souber onde esta o erro me ajude, me de uma luz. Obrigado desde já. Deixo aqui em baixo o código implementado em C no PIC C compiler.
