Question

We have ten 2-digits packed BCD numbers stored in ROM. Convert it into 20 unpacked BCD numbers and display on a common anode seven segment display connected with port Pl. Store these values in ROM: 0x15,0x 27,0x 35,0x 98,0x 65,0x 45,0x 72,0x 99.0x 85,0x 45 Firstly, I should be displayed to seven segment, then 5 should be displayed, then 2 then 7 and so on. write 8051 microcontroller assembly language program.

Answer 1

Answer:

write an 8051 assembly program to count all non zero bytes in the integer array of ten numbers stored in rom of 89c52 microcontroller. .Store the count value in r7,and store the index value of each nonzero byte on to stack.furthermore store the odd numbers found in array on scratch pad
