ISM Click Board
ISM Click Board
The ISM Click Board™ is a compact add-on board that contains a complete wireless RF digital data transceiver. This board features the RFM75, a low-power, high-performance 2.4GHz GFSK transceiver from RF Solutions. The RFM75 transceiver is configurable through SPI serial interface and operates with only 3.3V in the worldwide ISM frequency band from 2400MHz up to 2527MHz. The embedded packet processing engines enable their entire operation with a simple MCU as a radio system. Burst mode transmission and up to 2Mbps air data rate make it suitable for ultra-low power consumption applications.
This ISM Click Board™ is ideal for home appliances, remote control applications, consumer electronics, and many more.
Software Support
We provide a library for the ISM Click Board™ as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
The package can be downloaded/installed directly from NECTO Studio The package Manager (recommended), downloaded from our LibStock™ or found on mikroE Github account.
Library Description
This library contains API for the ISM Click Board™ driver.
Key Functions
ism_cfg_setup
- Config Object Initialization function.ism_init
- Initialization function.ism_default_cfg
- Click Default Configuration function.
Example Description
This library contains API for the ISM Click Board™ driver. This example transmits/receives and processes data from ISM Click Board™s. The library initializes and defines the UART bus drivers to transmit or receive data.
void application_task ( void ) { #ifdef RECEIVER uint8_t rx_buf[ ISM_MAX_PACKET_LEN ] = { 0 }; ism_receive_packet( &ism, &rx_buf[ 0 ] ); if ( rx_buf[ 0 ] != 0 ) { log_printf( &logger, " Rx : %s", rx_buf ); } #endif #ifdef TRANSMITTER ism_transmit_packet( &ism, ISM_CMD_W_TX_PAYLOAD_NOACK, &demo_message_1[ 0 ], 9 ); log_printf( &logger, " Tx : %s", demo_message_1 ); Delay_ms( 1000 ); ism_transmit_packet( &ism, ISM_CMD_W_TX_PAYLOAD_NOACK, &demo_message_2[ 0 ], 12 ); log_printf( &logger, " Tx : %s", demo_message_2 ); Delay_ms( 1000 ); #endif }
The full application code, and ready to use projects can be installed directly from NECTO Studio The package Manager (recommended), downloaded from our LibStock™ or found on mikroE Github account.
Other mikroE Libraries used in the example:
- MikroSDK.Board
- MikroSDK.Log
- Click.Ism
Additional Notes and Information
Depending on the development board you are using, you may need USB UART Click Board™, USB UART 2 Click Board™ or RS232 Click Board™ 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.
MIKROSDK
The ISM Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
