week 6 semester 2 - The program

here is where we reach the part which coding or programming take place. since the circuit have be troubleshoot and work properly, it need a program to complete the system. so, the program for this project or circuit not very complex or complicated, because it just want to show the display of the voltage input and the total voltage collected in the storage.

 //variables

unsigned int batA,batB,batC,batD;

unsigned char arr_batA[4],arr_batB[4],arr_batC[4],arr_batD[5];

{

//Lcd

Lcd_Config(&PORTB, 4, 5, 6, 3, 2, 1, 0); // Lcd_Init

Lcd_Cmd(Lcd_CLEAR);//Clear display

Lcd_Cmd(Lcd_CURSOR_OFF);//Turn cursor off

//relay
