Serial Buffer Options: RECEIVE_BUFFER=x TRANSMIT_BUFFER=x TXISR NOTXISR Flow Control Options: RTS = PIN_xx RTS_LEVEL=x CTS = PIN_xx CTS_LEVEL=x FLOW_CONTROL_MODE SIMPLEX_MODE peripheral. Using a serial routine (such as getc( ) or putc( )) before the UART is initialized will cause undefined behavior. Size in bytes of UART circular receive buffer, default if not specified is zero. Uses an interrupt to receive data, supports RDA interrupt or external interrupts. Size in bytes of UART circular transmit buffer, default if not specified is zero. If TRANSMIT_BUFFER is greater then zero specifies using TBE interrupt for transmitting data. Default is NOTXISR if TXISR or NOTXISR is not specified. TXISR option can only be used when using hardware UART. If TRANSMIT_BUFFER is greater then zero specifies to not use TBE interrupt for transmitting data. Default is NOTXISR if TXISR or NOTXISR is not specified and XMIT_BUFFER is greater then zero Pin to use for RTS flow control. When using FLOW_CONTROL_MODE this pin is driven to the active level when it is ready to receive more data. In SIMPLEX_MODE the pin is driven to the active level when it has data to transmit. FLOW_CONTROL_MODE can only be use when using RECEIVE_BUFFER Specifies the active level of the RTS pin, HIGH is active high and LOW is active low. Defaults to LOW if not specified. Pin to use for CTS flow control. In both FLOW_CONTROL_MODE and SIMPLEX_MODE this pin is sampled to see if it clear to send data. If pin is at active level and there is data to send it will send next data byte. Specifies the active level of the CTS pin, HIGH is active high and LOW is active low. Default to LOW if not specified Specifies how the RTS pin is used. For FLOW_CONTROL_MODE the RTS pin is driven to the active level when ready to receive data. Defaults to FLOW_CONTROL_MODE when neither FLOW_CONTROL_MODE or SIMPLEX_MODE is specified. If RTS pin isn't specified then this option is not used. Specifies how the RTS pin is used. For SIMPLEX_MODE the RTS pin is driven to the active level when it has data to send. Defaults to FLOW_CONTROL_MODE when neither FLOW_CONTROL_MODE or SIMPLEX_MODE is specified. If RTS pin isn't specified then this option is 142
PreProcessor not used. Purpose: This directive tells the compiler the baud rate and pins used for serial I/O. This directive takes effect until another RS232 directive is encountered. The #USE DELAY directive must appear before this directive can be used. This directive enables use of built-in functions such as GETC, PUTC, and PRINTF. The functions created with this directive are exported when using multiple compilation units. To access the correct function use the stream identifier. When using parts with built-in SCI and the SCI pins are specified, the SCI will be used. If a baud rate cannot be achieved within 3% of the desired value using the current clock rate, an error will be generated. The definition of the RS232_ERRORS is as follows: No UART: Bit 7 is 9th bit for 9 bit data mode (get and put). Bit 6 set to one indicates a put failed in float high mode. With a UART: Used only by get: Copy of RCSTA register except: Bit 0 is used to indicate a parity error. Warning: The PIC UART will shut down on overflow (3 characters received by the hardware with a GETC() call). The "ERRORS" option prevents the shutdown by detecting the condition and resetting the UART. Examples: Example Files: Also See: #use rs232(baud=9600, xmit=PIN_A2,rcv=PIN_A3) ex_cust.c getc(), putc(), printf(), setup_uart( ), RS2332 I/O overview #use rtos (The RTOS is only included with the PCW and PCWH packages.) The <strong>CCS</strong> Real Time Operating System (RTOS) allows a PIC micro controller to run regularly scheduled tasks without the need for interrupts. This is accomplished by a function (RTOS_RUN()) that acts as a dispatcher. When a task is scheduled to run, the dispatch function gives control of the processor to that task. When the task is done executing or does not need the processor anymore, control of the processor is returned to the dispatch function which then will give control of the processor to the next 143
