Integration with 8-bit PIC

The following integration steps work with 8-bit PIC MCU projects built using the MPLAB XC8 toolchain.

1. Copy xc8-pic-conf.h, unilcd.cpp, and unilcd.h files to the project source directory.
2. In default configiration YALI library reserved PB0, PB1, and PB2 to communicate with the LCD module. To change these pins modify the following definitions in the xc8-pic-conf.h file.
   • SHIFTREG_CLK_PIN - Clock output which is connected to the CLK terminal of the YALI module.
   • SHIFTREG_DATA_PIN - Data output connected to the DAT terminal of the YALL module.
   • SHIFTREG_LATCH_PIN - Latch control pin which is connected to the LAT terminal of the YALI module.
3. Connect the above mention outputs to the CLK, DAT, and LAT terminals of the YALI module.
4. Change the voltage setting of the YALI module to the appropriate setting based on the MCU supply voltage.
5. Connect the external power supply or system power terminals to the suitable DC input terminal of the YALI module.
6. To verify the connectivity flash the following sample program to the MCU:

#include "unilcd.h"
#include <xc.h> 
 
int main()
{
    initLCDInterface();
    __delay_ms(100);
 
    initLCD();  
 
    clearLCD();
    printString("LCD Test");
 
    while(1);
 
    return 0;
}
