Hello, I am working on something like that right now ! The aim of my project is to transmit 7 bytes with Aurel transmiters @ 1200 bps I use one pic for the emeter and an other for the receiver. I don't use other components (except the rf modules !). After the bytes are in the receiver's memory, you do what you want with ! It works quite fine but the receiver need some improvement in order to decode the code even if the emeter is far. I planed to make a web page about that when I manage to make a good code. But if somebody wants the draft code (which works !), just ask me ! Philippe Sorry for my english, it's not my natural langage... ----- Original Message ----- From: Peter McAlpine To: Sent: Thursday, February 10, 2000 10:57 PM Subject: key transmitters > Hi all, > I need to build a transmitter / recevier that sends > a data code, with the transmitter being a keyfob > type (aka remote entry on cars). > > Anyone point me in the direction of any circuit ideas > on this? > > Also, the Microchip keyloq device with code hoping, > can it send a unique data code that can be passed > through to another micro on decode?
