PIC16F877A/PIC16F887/PIC16/18F*** interface CH340 USB to TTL device

Hello folks,
This video is about how to interface a PIC wih CH340 device to interface with a computer or any other device using USB port.
If there is any problem feel free to comment:
Here is the code:
char rec1;
void main() {
TRISB.B7=0;
TRISB.B6=0;
UART1_INIT(1200);
DELAY_MS(400);
PORTB.B7=0;
PORTB.B6=0;
while(1)
{
if (UART1_Data_Ready() == 1) {
rec1 = UART1_Read();
DELAY_MS(200);
}

if ( rec1 == '1')
{
PORTB.B7=1;
DELAY_MS(800);
PORTB.B7=0;
rec1 = '0';
}
else if ( rec1 == '2')
{
PORTB.B7=1;
PORTB.B6=1;
DELAY_MS(800);
PORTB.B7=0;
PORTB.B6=0;
rec1 = '0';
}
else
{
PORTB.B7=0;
PORTB.B6=0;
rec1 = '0';
}
}
}
