AnalogOut | ( | PinName | pin | ) |
Create an AnalogOut connected to the specified pin.
pin | AnalogOut pin to connect to |

void write | ( | float | value | ) |
Set the output voltage, specified as a percentage (float)
value | A floating-point value representing the output voltage, specified as a percentage. The value should lie between 0.0f (representing 0v / 0%) and 1.0f (representing 3.3v / 100%). Values outside this range will be saturated to 0.0f or 1.0f. |
void write_u16 | ( | unsigned short | value | ) |
Set the output voltage, represented as an unsigned short in the range [0x0, 0xFFFF].
value | 16-bit unsigned short representing the output voltage, normalized to a 16-bit value (0x0000 = 0v, 0xFFFF = 3.3v) |
float read | ( | ) |
Return the current output voltage setting, measured as a percentage (float)
