Library Description

The library performs the check procedure for the desired outputs (IN1 - IN4). For more details check the documentation.

Key functions:

  • uint8_t digipot3_sendCommand( uint8_t commandByte ) - The function executes the desired command.
  • uint8_t digipot3_storeEEMEM( uint8_t location_address, uint16_t transfer_data ) - The function stores 16-bit data to the desired EEMEM (non-volatile) memory location.
  • uint8_t digipot3_writeDAC( uint16_t valueDAC ) - The function writes a 10-bit value to DAC register and determines the wiper position.
  • void digipot3_readDAC( uint16_t *dataOut ) - The function reads a 10-bit value from DAC register (wiper position).

Examples Description

The demo application is composed of three sections:

  • System Initialization - Initializes peripherals and pins.
  • Application Initialization -  Initializes SPI driver and restores the wiper position value from EEMEM (non-volatile) memory to the DAC register, if this value does not already exist in the DAC register.
  • Application Task - (code snippet) - Increments the wiper position by 6dB every 2 seconds. When wiper position reaches the desired value (0x0200), then the wiper position be decremented by 6dB every 2 seconds, until position value reaches the new desired value (0x0002). After that, the new position value will be stored in the EEMEM memory, if that value does not already exist in the EEMEM memory.
void applicationTask()
{
 while (digitalValue < 0x0200)
 {
 digipot3_sendCommand( _DIGIPOT3_INCREMENT_RDAC_6DB_COMM );
 digipot3_readDAC( &digitalValue );
 WordToStr( digitalValue, text );
 mikrobus_logWrite( "DAC value is: ", _LOG_TEXT );
 mikrobus_logWrite( text, _LOG_LINE );
 Delay_ms( 2000 );
 }

 while (digitalValue > 0x0002)
 {
 digipot3_sendCommand( _DIGIPOT3_DECREMENT_RDAC_6DB_COMM );
 digipot3_readDAC( &digitalValue );
 WordToStr( digitalValue, text );
 mikrobus_logWrite( "DAC value is: ", _LOG_TEXT );
 mikrobus_logWrite( text, _LOG_LINE );
 Delay_ms( 2000 );
 }

 if (eememValue != digitalValue)
 {
 digipot3_sendCommand( _DIGIPOT3_STORE_RDAC_TO_EEMEM_COMM );
 eememValue = digitalValue;
 }
}

mikroE Libraries used in the example:

  • Conversions
  • SPI
  • UART

Additional notes and information

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.

I2C Isolator 6 Click

0

I2C Isolator 6 Click is a compact add-on board that offers completely isolated bidirectional communication. This board features the ADUM2250, a two-channel, 5kVRMS I2C digital isolator from Analog Devices. The ADUM2250 provides two bidirectional channels, supporting a completely isolated I2C interface that eliminates the need for splitting I2C signals into separate transmit and receive signals for use with standalone optocouplers. It supports data rates from DC up to 1MHz and has a hot swap circuitry to prevent data glitches.

Color 18 Click is a compact add-on board for accurate ambient light detection and flicker monitoring. This board features the TCS3530, a true color ambient light sensor from ams OSRAM. The TCS3530 features true color XYZ sensing, flicker detection up to 7kHz, and eight concurrent sensing channels with independent gain configurations. It also includes a UV/IR blocking filter for precise light measurements and a unique Click Snap feature, allowing the main sensor area to become movable by breaking the PCB for flexible implementation.
