Welcome to Learning Microcontrollers youtube Channel,
Guys I have also compiled course on Udemy as well. Where you will learn under my direct supervision in a more supervised way.
Here is the links to the courses I have on Udemy, By taking any of these courses you will be supporting my channel aswell.
This will help me to make more videos with better hardware in the future. I hope you look forward to it.

As you know touchscreens and HMI are part of every machinery found in the market. Or even small projects require these screens. To have strong grip on using touch screens and interfacing them with microcontroller is very important is necessary. This tutorial teaches you how to interface a Nextion touch screen with a PIC16F877A microcontroller to turn on and off LEDs using mikroC for PIC coding.

MikroC code in the video is as under:
char read1;
void main() {
TRISD.F0 = 0;
PORTD.F0 = 0;
Delay_ms(100);
TRISD.F1 = 0;
PORTD.F1 = 0;
Delay_ms(100);
UART1_Init(9600);
Delay_ms(100);
while(1)
{
if (UART1_Data_Ready() == 1) {
read1 = UART1_Read();
Delay_ms(50);
}
if(read1 == 'a')
{
PORTD.F0 = 1;
Delay_ms(50);
}
else if(read1 == 'b')
{
PORTD.F0 = 0;
Delay_ms(50);
}
else if(read1 == 'c')
{
PORTD.F1 = 1;
Delay_ms(50);
}
else if(read1 == 'd')
{
PORTD.F1 = 0;
Delay_ms(50);
}
}
