''void analogWrite2(uint8_t ch, uint16_t value)''

===== Commands =====

^ Command ^ Arguments ^ Return Value ^ Operation ^
| ''analogWrite2(ch, value)'' | ''uint8_t ch''\\ ''uint16_t value'' | ''void'' | Outputs a raw value for 4~20mA conversion on the specified channel. |


===== Example =====

<code cpp>
void setup() {
  Serial.begin(115200);
  IanalogWriteInit(0, 1000, 0, false);  // Set the maximum, minimum and mode of MPAINO analog outputs.
}

void loop() {
  const int32_t demand = IanalogRead(0, 0, 1000);  // Map the analog input value to the specified integer range.
  IanalogWrite(0, 0, 1000, demand);  // Map the user's integer value to the analog output range and output it.
  analogWrite2(1, constrain(demand, 0, 1000));  // Output a raw value for 4–20mA conversion on the specified channel.
  delay(20);
}
</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()''.
