#45281 - Just one small example Responding to: ???'s previous message |
I know Ijaz and all other will be considering me as a Lazy student but please i really am a hard working guy...i have completed my 8 lines hardware with MT3271 DTMF dialing but this pulse dialing is creating all the problem so just a small example will really help...
just consider that Off Hook is at P2.1 now if the telephone goes off hook controller wait for pulse dialing and if the dialed Number is '0' then it connect the telephone set with X0 with Y0 of MT8816.. please a small example will stop me asking the same old question again and again...please... considering 60:40 Make / Break Ratio Inter Digit Space 800 Milli Seconds. 0 means 10 pps. |
