OLED W Click carries a 96 x 39px white monochrome passive matrix OLED display. The display is bright, has a wide viewing angle and low power consumption.
We provide a library for the OLEDW 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.
This library contains API for OLEDW Click driver.
oledw_cfg_setup
Config Object Initialization function.
void oledw_cfg_setup ( oledw_cfg_t *cfg );
oledw_init
Initialization function.
err_t oledw_init ( oledw_t *ctx, oledw_cfg_t *cfg );
oledw_send
This function sends commands or data to OLED W Click.
err_t oledw_send( oledw_t *ctx, oledw_data_t tx_data, oledw_data_mode_t data_mode );
oledw_display_picture
This function allows user to display picture for page addressing mode.
void oledw_display_picture( oledw_t *ctx, oledw_resources_t *pic );
oledw_set_contrast
This function sets the display contrast level (0 to 255).
void oledw_set_contrast( oledw_t *ctx, oledw_data_t value );
This example demonstrates the use (control) of the OLED W display.
The demo application is composed of two sections :
Configures the microcontroller for communication and initializes the Click board to default state.
void application_init ( void ) {
log_cfg_t log_cfg; /**< Logger config object. */
oledw_cfg_t oledw_cfg; /**< Click config object. */
/**
* Logger initialization.
* Default baud rate: 115200
* Default log level: LOG_LEVEL_DEBUG
* @note If USB_UART_RX and USB_UART_TX
* are defined as HAL_PIN_NC, you will
* need to define them manually for log to work.
* See @b LOG_MAP_USB_UART macro definition for detailed explanation.

}
for (i = 0x00; i < 0xAF; i++) {
oledw_set_contrast( &oledw, i );

}

oledw_scroll_diag_left( &oledw, 0x00, 0x05 );

oledw_stop_scroll( &oledw );
}
The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

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. UART terminal is available in all MikroElektronika compilers.
