Kindly ask help to use the same RS232 at different speed
this code:
while(1)
{
#use rs232(baud=19200,xmit=TXSER_A,rcv=RXSER_A,parity=N,bits=8)
putc(0x0f);
delay_ms(2);
#use rs232(baud=9600,xmit=TXSER_A,rcv=RXSER_A,parity=N,bits=8)
putc(0xf0);
delay_ms(2);
}
seems don't switch the speed like I need
I've also tryed to define 2 different function:
#use rs232(baud=19200,xmit=TXSER_A,rcv=RXSER_A,parity=N,bits=8)
writeHigh()
{
putc(0xf0);
}
---
#use rs232(baud=9600,xmit=TXSER_A,rcv=RXSER_A,parity=N,bits=8)
writeSlow()
{
putc(0xf0);
}
and then call them... but I'm always not able to switch the speed
working condition:
PIC16F916
TXSER_A= PIN_C6
RXSER_A= PIN_C7
hardware rs232
THANKS in advance for the help !
Have a nice day !
Enrico

Just use the set_uart_speed function...

All instructions beginning by # are for prepocessor so will never do any hardware changes.
Just use SET_UART_SPEED() as said by Ttelmah or SETUP_UART() for a complete setup.
