GCBASIC documentation
RS232 (hardware)

Syntax:

    HSerPrintStringCRLF user_string [,1|2|3|4]  'Choose comport with optional parameter
                                                'Default comport is 1

Command Availability:

Available on all microcontrollers with a USART or UART module.

Microchip PIC supports USART1 and 2.
Atmel AVR supports USART 1,2,3 and 4.

Enabling Constants:

To enable the use of the USART these are the enabling constants.   These constants are required.  You can change the USART_BAUD_RATE and to meet your needs.  For addition USART ports use #define USARTn_BAUD_RATE 9600 where n` is the required port number.

    'USART settings for USART1
    #define USART_BAUD_RATE 9600
    #define USART_TX_BLOCKING
    #define USART_DELAY OFF

Explanation:

HSerPrintStringCRLF is used to send a string over the serial connection. The parameter can only be a string. HSerPrintStringCRLF is very similar to HserPrint but HserPrint can handle all types of variables.

The data will be sent out the hardware serial module.

HSerPrintStringCRLF will send new line characters:

Example:

  'This program will display string over the serial connection.

  'Chip settings
  #chip 18F2525, 8

  'USART settings
  #define USART_BAUD_RATE 9600
  #define USART_TX_BLOCKING
