[slapdash41]

Hi there,

Can someone here explain to me how to store code into the PIC of this project. I totally don't understand even i already finished construct this project.Here's the link for this project

hope someone can help me to understand this things..

I have build another DTMF remote switch with MT8870 and PIC16F628 if you want i can send it for all people of the community.

first you connect telephone to connector K1
now you press switch s1 at that moment you can here a tone in the telephone connected to K1
now enter the dtmf tone by pressing the key on telephone

for Example

suppose you press 01611 then your ring count becomes 6
in the sme way you press 01811 then your ring count becomes 8
for ring count chenge you must enter first digit as 0 then second digit is any dtmf key and the third dight is the actual ring count then 4th and 5th digit is any dtmf key.

Example for on and off the relay

suppose you enter 14352 it is code for K1 to on in the same way you can enter the code for off the K1
as 24343
in this example the first digit of both code is the relay on off identifier 1 is for K1 to on and 2 is for K1 to off. the other four digits is any DTMF key which you want

What language did you use for coding? ASM or C? I would appreciate you if you could post your post here.

I've used picbasicpro it's easy to use

Could you please share your project with us? I've just completed a project that used PIC16F84 and MT8880. It works but need some more improvements.
