I want to receive and send a digit number(1,2,...,0,*,#) by mt8888 .it has an interface with DSPIC "33f.." . By initializing the mt8888 and applying some instruction I could send a digit and watched its related signal by osiloscope but I could not receive any digit . in fact I found that my problem is "detect nothing" when its related tone is recieved.after initializing , IRQ shall be set (it does) , and it seem by receiving a tone it shall be detected and then get an interrupt (on IRQ pin) . I have no success in having this interrupt since yet .
I tryed to initialize the chip as it is mentioned in datasheet . if any one help me it is appreciated.
