1. Extend Example 7-26 to convert 10 packed BCD numbers stored in an array to unpacked BCD numbers and display on Port Cand Port D, respectively. The array of packed BCD numbers is given below: PACKED_BCD [1] = {0x12, 0x23, 0x34, Ox45, Ox56, 0x67. Ox78, 0x89. 0x90,0x01),

Example 7-26 Write an AVR C program to convert packed BCD 0x29 to ASCII and display the bytes on PORTB and PORTC. Solution: //standard AVR header #include <avr/io.h> int main(void) unsigned char x,y: unsigned char mybyte 0x29; DDRB = DDRC - OxFF; Xmybyte & Ox0F; PORTB X I 0x30; y = mybyte & OxF0; Y y >> 4; PORTC= y 10x30; //make Ports B and C output //mask upper 4 bits W/make it ASCII //mask lower 4 bits //shift it to lower 4 bits //make it ASCII return 0; 3
