Click library

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

Software Support

We provide a library for the OledSwitch 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 OledSwitch Click driver.

Standard key functions :

  • Config Object Initialization function.

    void oledswitch_cfg_setup ( oledswitch_cfg_t *cfg );

  • Initialization function.

    OLEDSWITCH_RETVAL oledswitch_init ( oledswitch_t ctx, oledswitch_cfg_t cfg );

  • Click Default Configuration function.

    void oledswitch_default_cfg ( oledswitch_t *ctx );

Example key functions :

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

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

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

    void oledswitch_digital_write_pwm ( oledswitch_t *ctx, uint8_t signal );

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

    void oledswitch_digital_write_rst ( oledswitch_t *ctx, uint8_t signal );

Examples 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.

The demo application is composed of two sections :

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.

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:

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

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.

Load Cell 6 Click is a compact add-on board representing a weigh scale solution. This board features the MAX11270, a high-performance 24-bit delta-sigma ADC that achieves excellent 130dB SNR while dissipating an ultra-low 10mW from Maxim Integrated, now part of Analog Devices. This SPI-configurable ADC sample rates up to 64ksps allow precision DC and AC measurements, with integral non-linearity guaranteed to 4ppm maximum. The MAX11270 offers a 6.5nV/√Hz noise programmable gain amplifier with gain settings between 1x to 128x. Optional buffers are also included to isolate the signal inputs from the switched capacitor sampling network, which allows the MAX11270 to be used with high-impedance sources without compromising the available dynamic range.
