Hi,
I am developing Caller Line Indication (CLI) using 8888 DTMF Receiver and intefacing with 80C51 along with serial port.
Now it is working with outgoing tones digits.
But with incoming calls detection the digits are jumping and twice it displays.
in the hyperterminal
The problem is in the steering part where the RC time constant.
can u suggest me the RC time constant.
Please Help me.
