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

IperCODE is a didactic project, with which it is possible to build a remote control acquisition system, based on the rolling 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).

Receiver for Rolling Code REMOTE CONTROLS and other encoders

IperCODE is a didactic project, with which it is possible to build a remotely controlled acquisition system, based on rolling codes. The accepted remote controls must be of the same frequency of the module RECEIVER inserted into your project. The most common used encoders are Rolling Tails Keeloq, National MM53200 UM3750, Motorola MC145026 MC145027 MC145028.
