analogWrite2()

analogWrite2() outputs a raw value for 4~20mA conversion on the specified channel.

void analogWrite2(uint8_t ch, uint16_t value)

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);
}

• 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().
