Pessoal, comprei um controle remoto da marca ECP, com chip HT6P20, e com o código abaixo funcionou bem no arduino, até com um bom alcance, com uma antena de 50cm no receptor. O que não estou conseguindo é comparar o código recebido para implementar as rotinas. A comparação em vermelho, no final, é que não está funcionando: Alguém pode ajudar? /* TITLE: DECODER FOR HT6P20B ENCODER CREATED BY: AFONSO CELSO TURCATO DATE: 18/JUN/2014 E-MAIL: acturcato (at) gmail.com LICENSE: GPL REV.: 04 DESCRIPTION: http://acturcato.wordpress.com/2014/01/04/decoder-for-ht6p20b-encod...
