DIGITAL Potentiometer Additional Board
The DIGITAL Potentiometer additional board is used for digital resistance regulation. Resistance regulation is performed via SPI
communication between the additional board and the microcontroller supplied on a development system. The board is connected to
a development system via a 2x5 female connector on the additional board and a 2x5 male connector on the development system.
Depending on the development system to be connected to the additional board, it is necessary to set the appropriate switches on the DIP
switch SW1 to the ON position. Screw terminals CN2 and CN3 are used to connect the potentiometer to a controlled device (for example,
audio amplifier’s volume regulation). Next to these connectors, there are pins the marks of which have the following meanings:
PA
PW
PB
DIP switch SW1 is used to turn on MOSI, SCK and CS lines that connect a microcontroller and the aditional board.
When the DIGITAL Potentiometer board is connected to EasyPIC, LV18F, EasyLV-18F, Easy24-33 and BigPIC development systems,
the following switches on the DIP switch SW1 should be set to the ON position:
SW1-1 -> MOSI
SW1-4 -> SCK
For EasyAVR and Easy8051 development systems, the following switches should be set to the ON position:
SW1-3 -> MOSI
SW1-6 -> SCK
For the EASYdsPIC development system, the following switches on the DIP switch SW1 should be set to the ON position:
SW1-2 -> MOSI
SW1-5 -> SCK
The DIGITAL Potentiometer additional board is capable of regulating up to 10k resistance.
MCP41010 circuit is a
digital potentiometer
- potentiometer terminal A connection;
- potentiometer wiper connection; and
- potentiometer terminal B connection.
