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? :(
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...
