AFE_NXP_Arduino

Analog Front End device operation sample code for Arduino

What is this?

An Arduino library for NXP Analog Front End device with sample code.
This library provides simple API to get analog input channels.
Include device name header file (NAFE1338.h) to use those class libraries.

With AFE_NXP_Arduino library, characters can be shown by next sample code.

Note
Current version of NAFE13388_UIM class and its sample code is supporting Arduino UNO R3 only.

  Serial.println("logical channel 0 (AI1P-AICOM) and 1 (AI2P-AICOM) voltages are shown in micro-volt");
}
 
void loop() {
  Serial.print(afe.read(0));
  Serial.print(",  ");
  Serial.println(afe.read(1));
  delay(100);
