#99765 - 7 segent data bus tracker |
Sir
I am trying to a get the weighing scale output to PC.For this i am trying to decode the signals going to the 6 Sevensegment display.The data lines are from Po and control from P2.The sevensegment used is common anode. I am tapping all thses lines to another 89C51 P1 and P3 through 4081.Each output from weighing scale controller,I have given to one input of the And gate of 4081 each and the other input to 5v.The out put is read in the other controller. I am not getting anything but ff. If there is any other simple alternative please do suggest I hope have explaination of the problem is okey. |
