Muestra la forma de usar puerto serial pro software en PIC.en CCS, Mroc y XC8 sin MMC. Para micros de poca memoria y sin puerto serial. Aplicable para cualq. PIC16F877A UART example with CCS C. This is a small example shows how to use PIC16F877A UART module using CCS PIC C compiler. Pin RC6 (TX) and pin RC7 (RX) are used for the UART (serial) communication between the microcontroller and the computer. To change between TTL logic levels (5V) and RS232 signals (+/-12V), an IC is needed which is max232. UART Example for PIC16F887 CCS C code: The code used in this example is shown below. The function #use rs232 (UART1, baud = 9600) is used to configure the UART protocol. Here the hardware UART module is used. If the pins TX and RX (RC6 and RC7) are used by an other application we can use software UART. Software UART is generated by the compiler.
*Comunicacion Serial Rs232 Pic Ccs EnUsing Multiple RS-232 Ports on a PIC® MCU or PIC® DSC
In order to use multiple RS-232 connections on a PIC® MCU or PIC® DSC, multiple #USE RS232 pre-processor directives will need to be setup using the STREAM option. A #USE RS232 pre-processor directive will remain in effect for GETC, PUTC, PRINTF and KBHIT functions until another #USE RS232 is encountered.
The following example program shows how to read from one RS-232 port (A) and echo the data to both the first RS-232 port (A) and a second RS-232 port (B) without using the STREAM option for #USE RS232: Acer hs-usb diagnostics 33a0 driver download.

The following example program will perform the same operations as the one above. The STREAM option in the #USE RS232 pre-processor directive makes the code more readable and is therefore recommended method:
