| DISABLE 12LF1822 EUSART |

Hi everyone,
Still having challenges with the 12LF1822. Am trying to completely disable the EUSART - both transmit and receive.
Used setup_uart(0) and setup_uart_speed(0) but CCS C compiler (version 4.110) gave an error of unidentified for both.
Appreciate your suggestions.
Regards |

| DISABLE 12LF1822 EUSART |

Included the following code before main() to disable the EUSART:
#byte TXSTA=0x02
#byte RCSTA=0x08
The registers TXSTA and RCSTA are the registers for configuring the EUSART for the 12LF1822.
Regards. |

FWIW, If you take a look at the device header file:
| Quote: |
////////////////////////////////////////////////////////////////// UART
// Constants used in setup_uart() are:
// FALSE - Turn UART off
// TRUE - Turn UART on
|

Thanks dyeatman.
I actually tried that but got a compiler error of "undefined identifier".

You will get that error, if you have not got a #USE RS232 using the hardware UART (the UART is _off_ in this case anyway).
The setup_uart command, only becomes supported if UART code is present.
