IanalogWriteInit()
IanalogWriteInit() sets the maximum, minimum and mode of the MPAINO analog output.
void IanalogWriteInit(uint8_t ch, uint32_t maxValue = 65535UL, uint32_t minValue = 0, bool mode = false)

IanalogWriteInit(ch, maxValue, minValue, mode) | uint8_t chuint32_t maxValue = 65535ULuint32_t minValue = 0bool mode = false | void | Sets the maximum, minimum and mode of the MPAINO analog output. |
Example
This example uses MPAINO-8A8R(T) with a Y output module and Analog Output Module → Y selected. It sets CH0 to a 0–1000 range and outputs its midpoint.
void setup() { IanalogWriteInit(0, 1000, 0, false); // Set Y module CH0 to a 0–1000 range. } void loop() { IanalogWrite(0, 0, 1000, 500); // Output the midpoint of the configured range. delay(500); }
Precautions
- Match the module DIP switches, external power supply and output range.
- Do not configure these together with PWM functions sharing the same timer.
- Do not output values to uninitialized channels.
- Currently, MPAINO Y analog output supports channels up to
0~11; do not use12~15. analogWriteInit(),analogWriteFreq()andanalogWriteMax()are for Y analog output channels and must not be used for high-speed pulse channels20~31.- Do not use high-speed pulse GPIO numbers
