Coding

• Coding: Open the main.c file and add the following code to the main(void) function.

main.c

#include "cyhal.h"
#include "cybsp.h"
#include "stdio.h"

#include "cy8ckit_028_sense.h"
#include "GUI.h"

// Define function
void lcd_print_top(const char * s);
void lcd_print_bot(const char * s);
void lcd_print_line_n(const char * s,int linenum);

cyhal_i2c_t i2c;
cyhal_i2c_cfg_t i2c_cfg = {
    .is_slave = false,
    .address = 0,
    .frequencyhal_hz = 400000
};


int main(void)
{
    cy_rslt_t result;
    char str[80];

    /* Initialize the device and board peripherals */
    result = cybsp_init();
    CY_ASSERT(result == CY_RSLT_SUCCESS);
    __enable_irq();

    /* Initialize i2c */
    result = cyhal_i2c_init(&i2c, CY8CKIT_028_SENSE_PIN_I2C_SDA, CY8CKIT_028_SENSE_PIN_I2C_SCL, NULL);
    CY_ASSERT(result == CY_RSLT_SUCCESS);
    result = cyhal_i2c_configure(&i2c, &i2c_cfg);
    CY_ASSERT(result == CY_RSLT_SUCCESS);

    /* Initialize the OLED display */
    result = mtb_ssd1306_init_i2c(&i2c);
    CY_ASSERT(result == CY_RSLT_SUCCESS);

    GUI_Init();


    for (;;)
    {
        lcd_print_line_n("   .--.   ", 1);
        lcd_print_line_n("  |o_o |  ", 2);
        lcd_print_line_n("  |:_/ |  ", 3);
        lcd_print_line_n(" //   \\ \\", 4);
        lcd_print_line_n("(|     | )", 5);
        lcd_print_line_n("/'\\_   _/`\\", 6);
        lcd_print_bot("\\___)=(___/");
        cyhal_system_delay_ms(1000);          // Wait for 1 second before
    }

}


 // Create function

void lcd_print_top(const char * s){
	GUI_GotoXY(0,0);
	GUI_DispString(s);
}

void lcd_print_bot(const char * s){
	GUI_GotoXY(0,50);
	GUI_DispString(s);
}

void lcd_print_line_n(const char * s,int linenum){ //linenum is 1-6
	int line = (linenum-1)*10;
	GUI_GotoXY(0,line);
	GUI_DispString(s);
}
