[edsim51] Problem about scanning keypad
hello!! Ｉam a begineer to assembly program
i meet a problem about keypad of edsim51
https://www.edsim51.com/examples.html#prog7
Further exercises for the student might be:
Write extra code that displays the key symbol on one of the 7-segment displays. For example, if key 4 is pressed, the number 8 appears on the display. If key 10 is pressed the number 2 appears on the display. (Note: the symbols # and * cannot be displayed on a 7-segment display, but some special characters could be invented and displayed instead.
i am a self learner and i fail to do that after trying a long time.
Can anymore one teach me how to display the right digit which match the key i pressed?
