interface 8085 microprocessor with 4K RAM, 256 bytes RAM, 2K RAM and 6K ROM using decoders and gates?
4195write down a program to that reads the data from port 02H, count the number of 1's in the data and display the count on port 03H in 8085 microprocessor
1316draw the interface diagram of 8085 microprocessor having input ports at 23H, 2FH, EFH, and output ports at 44H, 2FH, EFH, and FFH using NAND gates only.
1401with a neat sketch, show all the interconnections required between a 8085 processor and a RAM of size 4KB mapped in the range 2000H-2FFFH.
1370interface an 8-pin switch with 8085 microprocessor located at 0AAH and LEDs at port 55H, draw the circuit diagram. Write down a program to read the switches and do the following: > if the parity of the switch is odd, start counting upward until it reaches 0FFH. > if the parity of the switch is even, start counting downwards until it reaches 00H.
