[PIC] #use rs232 syntax for ccs

[Kumar Sin]

I have project which has few files. One of the files I have #use syntax to initialize the uart1 for pic18F87J11 controller.

#use rs232(uart1, baud=19200, parity=N, xmit=PIN_C6, rcv=PIN_C7, bits=8)
#int_RDA
void RDA1_isr(void)
{
UCHAR receive_byte;
.......................
.............
}

In another file I have another #use syntax to initialize the uart2.

#use rs232(uart2, baud=19200, parity=N, xmit=PIN_C6, rcv=PIN_C7, bits=8)

When I compile the project file with the ccs compiler I get the above message,

-- Info 300 "C:\My_Test_HCA\HCA\Code\FS1K_intrpt.c" Line 448(5,8): More info: First Declaration of STDIN
*** Error 31 "C:\My_Test_HCA\HCA\Code\pic_RemPanel.c" Line 730(5,74): Identifier is already used in this scope
1 Errors, 1 Warnings.
Build Failed.

Somehow the compiler doesn't like the #use syntax 2 times. If I remove either one it compiles well.

I am new to the ccs compiler. Appreciate your help.

#use rs232 means a fully static usage of the UART.

If you know the one-and-only baud rate then use it for it and for more than one UART connection with PIC you can change the UART for 2nd UART is using setup_uart();function.
