i am looking for ideas on how to build a circuit to display 2 digit error codes on seven segment displays
from pulses from an ecu
at the moment you have to count the led flash ie error code 46 is
flash 4 times pause flash six times and display 10 but which if it was error 55 would also display 10
i thought of using two cd4026 decade counters but
if you had error code 26 ie flash 2 pause flash 6 it would display 8 and if the code was 44 it would be flash 4 pause flash 4 this would also display error 8
which is no good i need it to display the code from the pulses ie display 4 pause 4 as error 44
and 2 pause 6 as error 26
