// JavaScript Examples
var dac = obniz.wired("MCP4725", {sda:0, scl:26});
dac.setVoltage(1.5);
setVCCVoltage(number)
Store applied VCC voltate. Default is 5v. It must be equal to vcc voltage of connected chip.
// JavaScript Examples
var dac = obniz.wired("MCP4725", {sda:0, scl:26});
dac.setVCCVoltage(3.3);
dac.setVoltage(1.5);
setVoltage(voltage)
make the potential difference.
specify a value between 0 and 3.3(V).
Use setVCCVoltage() before if vcc is different from 5.0v.
// JavaScript Examples
var dac = obniz.wired("MCP4725", {sda:0, scl:26});
dac.setVoltage(1.5);
Supported from: obniz.js 3.5.0
