hi all...
i need to transmit bits from pc to pic...
i dont know how to start apart from this code i got hold of
so from what i know is that i need to configure uart receiving (pic).. and im using rs-485 to communicate.. hence theres a rs232 to rs485 converter..
so here's the order
hyperterminal > rs232/rs485 converter > rs485 > pic...
i need to transmit bits from pc to pic...
i dont know how to start apart from this code i got hold of
Code:
#include <p18C452.h>
#include <usart.h>
void main(void)
{
// configure USART
OpenUSART( USART_TX_INT_OFF &
USART_RX_INT_OFF &
USART_ASYNCH_MODE &
USART_EIGHT_BIT &
USART_CONT_RX &
USART_BRGH_HIGH,25 );
while(1)
{
while( ! PORTAbits.RA0 ); //wait for RA0 high
WriteUSART( PORTD ); //write value of PORTD
if(PORTD == 0x80) // check for termination
break; // value
}
CloseUSART();
}
