Hi, I have made a simple ring detection device that transmits a signal to operate light/sound/vibration. I also wanted to add a Caller ID facility to the transmitter iterface of my project, but this does not need to be transmitted, just an LCD screen to show the name or number (as it should work on a PBX also). From my understanding as i am in the UK i need to use a FSK based system (SIN227). I have looked into a few decoders such as IDT NW6005 and Mitel MT8843, and it seems straighforward, but i wanted to use a PIC chip to display the information on an LCD, but all project etc seems to use the decoder chips but for DTMF? I dont want to over complicate anything, i just need to create a basic addition that shows a caller id and maybe a button to clear the screen aftrerwards. Any help would be much appreciated as i have searched the internet for days!
