Examples Description

This example shows how to read ADC value from MCP3551, and usage of LED Driver MAX6969 via SPI. When user changes the position of the slider, the LEDs on the click will turn ON and OFF accordingly.

The application is composed of two sections :

• System Initialization - Initializes GPIO pins, SPI peripheral used for MCP3551 and MAX6363
• Application Task - Sequentially reads ADC value from MCP3551 and show measurement using Slider click built-in bar graph.

void applicationInit()
{
// READ ADC MCP3551
    adcValue = MCP3551_Read() / DIVIDER;

// RECALCULATE VALUE
    if (adcValue > 99)
    {
        adcValue = 100;
    }
    adcValue = adcValue / 6;

// SHOW MEASUREMENTS USING SLIDER BARGRAPH
    bargraph( adcValue );
}
