hi
still working on my 8051 project using assembly language, and now I'm in phase 4 --->>>> the last phase
in this phase we should generate 2 random numbers as following:
1. one digit (1-9)
2. two digit (10-99)
and by using push button we pick randomly the number
we have done one digit perfectly, but we face a problem with the two digit
we used a counter with 99 numbers and decrements it each time until the user push a button to interrupt the function and show the number randomly
but the problem that it shows the one digit also
we tried to make the counter to start from 10 and increment it each time until we reach 99 --->>> but also it didn't work
we tried and tried and tried
the code :
please help
