no reply about the program,well one problem configured.
suppose a motor with 500rpm is to be used then the program should display 480 or 540 since in 1second there will be either 8 or 9 revolutions respectively but instead it will display the bcd value of 480(111100000) i.e 240 or bcd value of 540(001000011100) i.e 222 also bcd is required since 7447 bcd to 7-segment decoder used is there any means by which this problem can be solved |
