The aim of the project is to detect IR signals in the environment using an LPC2148 microcontroller board and print the output on an LCD connected to it. The project aims to investigate the encoding mechanisms employed by these protocols, with a particular emphasis on the pulse and space distances used in the transmission. Using a sensor (TSOP 1838 - active low), the project aims to capture transmitted IR signals and decode them using the LPC 2148 (ARMv7) micro-controller. The implementation involves utilizing external interrupts and timers to decode the protocols, providing valuable insights into the signal processing and control mechanisms of IR remotes.
The simulation was performed on Proteus and the programming was done on Keil uVision4 software.
