RS485 2 click is an RS422/485 transceiver Click boardâ„¢, which can be used as an interface between the TTL level UART and the RS422/485 communication bus.
We provide a library for the Rs4852 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 Rs4852 Click driver.
void rs4852_cfg_setup ( rs4852_cfg_t *cfg );
RS4852_RETVAL rs4852_init ( rs4852_t *ctx, rs4852_cfg_t *cfg );
void rs4852_default_cfg ( rs4852_t *ctx );
void rs4852_power_mode ( rs4852_t *ctx, uint8_t pin, uint8_t state );
void rs4852_generic_single_write ( rs4852_t *ctx, rs4852_data_t tx_data );
rs4852_data_t rs4852_generic_single_read ( rs4852_t *ctx );
This demo example shows RS485 communication using RS485 2 click.
The demo application is composed of two sections :
Configuring clicks and log objects.
Depending on the selected application mode:
- DEMO_APP_TRANSMITER - Prints "MikroE" message to UART
- DEMO_APP_RECEIVER - Reads data from uart and prints to LOG (Default)
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.
Other mikroE Libraries used in the example:
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.
