Library description
The library carries two functions which are sufficient to have complete control over DIGI POT 4 click.
Key functions:
void digipot4_writeReg(uint8_t Reg, uint16_t value);- Write data to wiper register
void digipot4_copyReg(uint8_t Reg);- Copy data to NV memory
Example description
The application is composed of three sections :
- System Initialization - Initializes SPI module and sets CS pin as OUTPUT
- Application Initialization - DIGI POT 4 Driver initialization
- Application Task - (code snippet) - Sequentially sets the wiper position every second.
void applicationTask()
{
digipot4_writeReg(_DIGIPOT4_WIPER_REG_1, 0);
digipot4_writeReg(_DIGIPOT4_WIPER_REG_2, 0);
Delay_1sec();
digipot4_writeReg(_DIGIPOT4_WIPER_REG_1, 512);
digipot4_writeReg(_DIGIPOT4_WIPER_REG_2, 512);
Delay_1sec();
digipot4_writeReg(_DIGIPOT4_WIPER_REG_1, 1023);
digipot4_writeReg(_DIGIPOT4_WIPER_REG_2, 1023);
Delay_1sec();
}
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.
