数据采集分为模拟量采集和数字量采集两种,此处设置采集路数各为2路,分别采用Arduino Uno控制器上具有模拟量输入的管脚A0、A1和具有数字量输入的管脚2、3。 Arduino Uno控制器负责读取LabVIEW上位机发来的采集命令,并采集相应的数据,通过串口发送回上位机LabVIEW软件。Arduino Uno控制器的程序代码如代码如下所示: ...
I tried passing a potentiometer value which is read on ADC to PWM but it didn’t work. can you walk me through how to do it? BTW below is the code I wrote: const int ledPin=16; const int potPin=4; const int freq=5000; const int ledChannel=0; const int resolution=16; int duty...
“If you want to output PWM signals based on the input voltage of the ADC pin, you need to convert the ADC values to a range of 0 to 255. You need to do this because the PWM output only has 8-bit resolution” I think that PWM output 8-bit resolution is for Arduino Uno. ...
In addition to digital pins, the Nano sports 8 analog input pins (A0-A7). These provide a 10-bit resolution ADC, which can be read using the analogRead() function. Notably, the Nano offers more analog pins than the Arduino UNO, which has only 6. If needed, all analog pins, except ...
