====== IanalogWriteInit() ======

''IanalogWriteInit()'' sets the maximum, minimum and mode of the MPAINO analog output.

{{:en-us_commands:reference:ianalogwriteinit.svg?900|IanalogWriteInit command operation flow}}

''void IanalogWriteInit(uint8_t ch, uint32_t maxValue = 65535UL, uint32_t minValue = 0, bool mode = false)''

===== Commands =====

^ Command ^ Arguments ^ Return Value ^ Operation ^
| ''IanalogWriteInit(ch, maxValue, minValue, mode)'' | ''uint8_t ch''\\ ''uint32_t maxValue = 65535UL''\\ ''uint32_t minValue = 0''\\ ''bool 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.

<code cpp>
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);
}
</code>

===== 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 use ''12~15''.
  * ''analogWriteInit()'', ''analogWriteFreq()'' and ''analogWriteMax()'' are for Y analog output channels and must not be used for high-speed pulse channels ''20~31''.
  * Do not use high-speed pulse GPIO numbers ''130~141'' with ''analogWrite()''.
