OLED Switch Click

OLED Switch Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Click Library

• Author : MikroE Team
• Date : Feb 2020.
• Type : SPI type

Software Support

Example Description

This example showcases how to configure and use the OLED Switch Click. This Click is a combination of a button and a full color organic LED display. Displays settings are first loaded onto the chip and after that you can show any 64x48 pixel image on the display.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.OledSwitch

Example Key Functions

• oledswitch_cfg_setup Config Object Initialization function.

void oledswitch_cfg_setup ( oledswitch_cfg_t *cfg );

• oledswitch_init Initialization function.

err_t oledswitch_init ( oledswitch_t *ctx, oledswitch_cfg_t *cfg );

• oledswitch_default_cfg Click Default Configuration function.

void oledswitch_default_cfg ( oledswitch_t *ctx );

• `` This function writes to control and configuration registers on the chip.

oledswitch_reg_write  ( oledswitch_t *ctx, uint8_t *write_buf, uint8_t len );

• oledswitch_digital_write_pwm This function sets the digital output signal for the PWM pin.

void oledswitch_digital_write_pwm ( oledswitch_t *ctx, uint8_t signal );

• oledswitch_digital_write_rst This function sets the digital output signal for the RST pin.

void oledswitch_digital_write_rst ( oledswitch_t *ctx, uint8_t signal );

Application Init

This function initializes and configures the Click modules. In order for the Click to work properly, you need to configure display and power settings. The full initialization of the chip is done in the default_cfg(...) function.

void application_init ( )
{
    oledswitch_cfg_t cfg;
    
    //  Click initialization.

    oledswitch_cfg_setup( &cfg );
    OLEDSWITCH_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    oledswitch_init( &oledswitch, &cfg );
    oledswitch_default_cfg( &oledswitch, OLEDSWITCH_BUFFER_SIZE_SMALL );
}

Application Task

This function shows the user how to display images on the OLED screen. Every image you'd like to display needs to have a resolution of 64x48 and be stored in a 6144 cell array.

void application_task ( )
{
    oledswitch_draw_image( &oledswitch, array_red, OLEDSWITCH_IMG_SIZE_NORMAL );
    Delay_1sec( );

    oledswitch_draw_image( &oledswitch, array_green, OLEDSWITCH_IMG_SIZE_NORMAL );
    Delay_1sec( );

    oledswitch_draw_image( &oledswitch, array_blue, OLEDSWITCH_IMG_SIZE_NORMAL );
    Delay_1sec( );
}

Note

Every pixel on the OLED screen is displayed at the time of writing to the chip (PWM 1). Displaying speed can be directly controled by adding delays in the for loop section of the draw_image(...) function.

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
