hello!!! im having a project that requires me to interface DTMF(MT8889C) with 8051 Micro-controller using uVision(.a51). Please anyone that have the codes or could teach how-to on the above application? :(
I think that you will find some useful information at http://www.8052.com - do a search for DTMF.
You will increase your chances of useful answers by: 1. Putting a sensible, relevant, descriptive subject on your post 2. Demonstrating that you have made some effort on your own part; ie, Read the datasheet; Searched the manufacturer's site for application notes; Done your own internet search for relevant resources already available.
hi~ sorry for posting this topic, but I hope someone will assist me because I have absolutely no programming background at all. im not trying to be lazy.. but i cant "see" how to read the 8051 chip schematics and how actually it communicates with the mt8889c. i tried to find some sample codes on that on the net but all in vain...
