OOK TX click

OOK TX click is a simple wireless transmitter that operates at the frequency of 433MHz (sub-GHz). This device allows realization of a simple, low-speed wireless ad-hoc communication network between a transmitter and compatible receiver, such as the OOK RX click.

Click library

Software Support

We provide a library for the OOKTX 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.

Library Description

This library contains API for OOKTX Click driver.

Standard key functions :

Example key functions :

Examples Description

This example showcases how to initialize and use the OOK TX click. The click encodes information

using the On-Off Keying modulation, embeds it in a 433 MHz radio signal and acts as a transmitter for this signal. The OOK RX click should play the role of the receiver in this communication.

The demo application is composed of two sections :

Application Init

This function initializes and configures the logger and click modules.

{
log_cfg_t log_cfg;
// Logger initialization.
log_cfg.level = LOG_LEVEL_DEBUG;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info(&logger, "---- Application Init ----");
// Click initialization.
ooktx_cfg_setup( &cfg );
OOKTX_MAP_MIKROBUS( cfg, MIKROBUS_1 );
ooktx_init( &ooktx, &cfg );
Delay_100ms( );
}

Application Task

This function initiates the radio signal communication, sends an 8 byte preambule, 2 start

package bytes to help the receiver differentiate actual data packages from signal glitches, sends the actual data byte and stops the communication in one iteration.

{
uint8_t cnt;
uint8_t inc;
for ( ; ; )
{
for ( cnt = 0; cnt < 8; cnt++ )
{
}
ooktx_communication_transmit( &ooktx, inc++ );
Delay_ms ( 1000 );
}
}

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.
