Library description
The library contains functions that perform basic SPI commands on click board registers.
Key functions:
uint8_t digipot5_writeReg(uint8_t regAddress, uint16_t writeData);- Function writes to the click board registers
uint8_t digipot5_readReg(uint8_t regAddress, uint16_t * pReadData);- Reads from the click board registers
uint8_t digipot5_setResistance(uint8_t regAddress, uint16_t value);- Sets the resistance of the selected wiper

Additional notes and information
Depending on the development board you are using, you may need USB UART click, USB UART 2 clickor 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.
