2.0.0.0
|
2x2 Key click has a 4 button keypad and allows multiple key presses.
We provide a library for the 2x2key 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 2x2key Click driver.
void c2x2key_cfg_setup ( c2x2key_cfg_t *cfg );
C2X2KEY_RETVAL c2x2key_init ( c2x2key_t *ctx, c2x2key_cfg_t *cfg );
void c2x2key_default_cfg ( c2x2key_t *ctx );
uint8_t c2x2key_t1_state ( c2x2key_t *ctx );
uint8_t c2x2key_t2_state ( c2x2key_t *ctx );
uint8_t c2x2key_t3_state ( c2x2key_t *ctx );
uint8_t c2x2key_t4_state ( c2x2key_t *ctx );
This example code demonstrates the usage of 2X2 Key Click board.
The demo application is composed of two sections :
Application Init performs Logger and Click initialization.
Application Task detects whether any of the keys is pressed, and results are being sent to the UART Terminal where you can track changes.
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.
