Question

1. For the decimal number 15, give the packed BCD and unpacked BCD representations: 2. 67H in BCD when converted to ASCII is H and H. 3. Does the following convert unpacked BCD to ASCII? mydata = 0x09 + 0x30; 4. Find the checksum byte for the following values: 22H, 76H, 5FH, 8CH, 99H. 5. Review the example in class and write an AVR C program to send out the value 4AH serially one bit at a time via PORTB, pin 4. The MSB should go out first. Must include proper comments. Put the code in compiler (either use Arduino program or online simulation program) and make sure it can be compiled.

          1. For the decimal number 15, give the packed BCD and unpacked BCD representations:
2. 67H in BCD when converted to ASCII is ____ H and ____ H.
3. Does the following convert unpacked BCD to ASCII?
mydata = 0x09 + 0x30;
4. Find the checksum byte for the following values: 22H, 76H, 5FH, 8CH, 99H.
