rs232spi 2.0.0.0
|
RS232 SPI click is based around the MAX3100, a universal asynchronous receiver transmitter (UART) - the first UART specifically optimized for small microcontroller-based systems, from Maxim Integrated. Because of the features contained in its modules, the RS232 SPI click can be used for handheld instruments, small networks in HVAC or Building control, UART in SPI systems, battery-powered systems, PDAs, notebooks and many more.
We provide a library for the Rs232Spi Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.
This library contains API for Rs232Spi Click driver.
- Initialization function.void rs232spi_cfg_setup ( rs232spi_cfg_t *cfg );
RS232SPI_RETVAL rs232spi_init ( rs232spi_t *ctx, rs232spi_cfg_t *cfg );
void rs232spi_default_cfg ( rs232spi_t *ctx );
- This function reads two bytes of data using the SPI serial interface.void rs232spi_reg_write ( rs232spi_t *ctx, uint16_t write_data );
uint16_t rs232spi_reg_read ( rs232spi_t *ctx, uint16_t write_data );
void rs232spi_digital_write_rst ( rs232spi_t *ctx, uint8_t signal );
This example showcases how to initialize and use the RS232 SPI click. The click has a uni- versal asynchronous transceiver which uses a SPI serial interface to communicate with the MCU. In order for this example to work, 2 clicks are needed - a receiver and a transmitter.
The demo application is composed of two sections :
This function initializes and configures the logger and click modules. Additional configura- ting is done in the default_cfg(...) function.
This function receives and displays UART data in the "read mode" and sends the predefined message in the "write mode".
The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Additional notes and informations
Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
