CODE SNIPPET

The following code snippet shows how to cycle through different output voltages.

01 void main() 
02 {
03     systemInit();
04 
05    while (1)
06     {
07         delay_ms(3000);
08         //Sets the voltage to VOUTmax, ~5.25 V
09         CS_PIN = 0;       //Sets chip select to active
10         Spi3_Write(0b01110000);
11         Spi3_Write(0b00000000);
12         CS_PIN = 1;       //Sets chip select to inactive
13 
14        delay_ms(3000);
15         //Sets the voltage to VOUTmin, which depends on VIN, but cannot
16         //be lower than 2.50 V
17         CS_PIN = 0;       //Sets chip select to active
18         Spi3_Write(0b01111111);
19         Spi3_Write(0b11111111);
20         CS_PIN = 1;       //Sets chip select to inactive
21         
22        delay_ms(3000);
23         //Sets the voltage ~4.0 V
24         CS_PIN = 0;       //Sets chip select to active
25         Spi3_Write(0b01110111);
26         Spi3_Write(0b01000000);
27         CS_PIN = 1;       //Sets chip select to inactive
28 
29        delay_ms(3000);
30         //Sets the voltage ~4.5 V
31         CS_PIN = 0;       //Sets chip select to active
32         Spi3_Write(0b01110100);
33         Spi3_Write(0b00011111);
34         CS_PIN = 1;       //Sets chip select to inactive
35     }
