Matrix RGB Click is a mikroBUS™ add-on board powered by a 32-bit FT900 MCU designed specifically for powering 16x32 RGB LED matrices.
We provide a library for the MatrixRGB 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 MatrixRGB Click driver.
Config Object Initialization function.
void matrixrgb_cfg_setup ( matrixrgb_cfg_t *cfg );
Initialization function.
MATRIXRGB_RETVAL matrixrgb_init ( matrixrgb_t ctx, matrixrgb_cfg_t cfg );
Click Pattern Settings ( Default Configuration ) function.
void matrixrgb_pattern_settings ( matrixrgb_t *ctx, uint8_t pattern_type, uint16_t pattern_delay_us );
Set Power
void matrixrgb_set_power ( matrixrgb_t *ctx, uint8_t power_state );
Set Brightness
void matrixrgb_set_brightness ( matrixrgb_t *ctx, uint8_t brightness );
Write Pixel
uint8_t matrixrgb_write_pixel ( matrixrgb_t *ctx, uint16_t x, uint16_t y, uint16_t color );
This application is used for powering 16x32 RGB LED matrices.
The demo application is composed of two sections :
Initializes driver, reset device and initializes firmware depend on pattern used alongside with fonts

{
log_cfg_t log_cfg;
matrixrgb_cfg_t cfg;
matrixrgb_font_t font_cfg;

* Default log level: LOG_LEVEL_DEBUG

* need to define them manually for log to work.
* See @b LOG_MAP_USB_UART macro definition for detailed explanation.

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.
