The August issue of Silicon Chip magazine published a circuit that I designed recently. Unfortunately, the item in the Circuit Notebook section was titled "Universal IR remote control repeater", instead of the more correct "Universal IR remote control receiver" or perhaps "receiver/decoder". I invite Silicon Chip readers interested in IR to have a closer look. The PICAXE code file should be available for download from the Silicon Chip website shortly.
The design uses any PICAXE chip that can run at 8 MHz. It reliably receives and decodes 32-bit NEC format IR codes. The NEC 32-bit code seems to be the most common remote control format in use. It offers 256 or 65,536 different devices and 256 individual codes with error checking.
