RX receiver for Rolling code remote controls (Microchip), National and Motorola

IperCODE is a plan realized for didactic use, with which it is possible to realize an acquisition system remote control based on the previous codes and to have the possibility to transmit the received code on RS232 serial, to visualize it on the 16X2 display or to reproduce it, transmitting it by radio. Therefore you can make experiments with the peripheral of the PIC16F876 the UART, the Capture Compare, the PWM and the management of the inner EEPROM for saving the received code. The plan can be considered a basic for development, and it can easily adapt to your requirements, as an example, if the inner memory is not enough, it can be connected a I2C or SPI memory on the pin of the micro, left free in that purpose. To import the code you'll have to press the LEARN key for more than 5 seconds or holding the ignition key, while for the transmission of the code you'll just have to press it normally (if you want you can add an additional key).
