DIGI POT 2 click From MikroElektonika Documentation DIGI POT 2 click is a mikroBUS add-on board with a single channel digital potentiometer TPL0501 with 256 wiper positions. The IC has 100 kilo Ohms end-to-end resistance, with ±20% tolerance. The board features two pairs of screw terminals for interfacing with the IC DIGI POT 2 click communicates with the target MCU through the mikroBUS SPI pins MISO, MOSI, SCK, CS . The board is designed to use either a or a 5V power supply.

Rheostat mode B

DIGI POT click can operate in several configurations:

Voltage Divider mode Rheostat mode A

More details on each one can be found in the TPL0501 data sheet.

Digital potentiomenters can be have any kind of interface. Not just knobs like mechanical potentiometers, but also buttons, capacitive inputs etc .

Another advantage of digital potentiometers is that you can create any desirable sweep profile linear, digital or any other function .

The operating temperature of TPL0501 is between -40ºC to 125ºC. ESD performance is tested per JESD 22 requirements human body model .

DIGI POT 2 click can be used both with a 3.3V or a 5V power supply, as determined by the position of the onboard jumper soldered to 3.3V position by default .

Programming

The following code snippet shows a larger part of the DIGI POT 2 click example we supply:
1 void main
3 Delay_ms 100 ;
5 while 1
// Endless loop

DigPot_CS = 0;
// Select PotentioMeter chip

SPI1_Write 0 ;

SPI1_Write counter ;

SPI1_Write 0x20 ;

SPI1_Write counter ;

DigPot_CS = 1;
// Deselect PotentioMeter chip
adc_value = ADC_Read 1 ;
// Get 10-bit results of AD conversion

PORTD = unsigned char adc_value >> 2 ;
if PINB2_bit
// Press PB2 to decrease resistance between W and L
