Arduino Due - DAC constant Sampling rate. Hi, I build simple code when first the user send command via serial port to the board which select different vectors (12 bit vectors with different length) and then when the user push external interrupt button the DAC port write the selected vector. The purpose of this project is to “PLAY” different vectors with minimal latency …

Compatible with Arduino Due only. The Audio library enables an Arduino Due board to play back .wav files from a storage device like an SD card. The Due uses the DAC0 and DAC1 pins to play sounds. To use this library #include <Audio.h> NB : The Audio library and associated functions are experimental. While it is not likely the API will change in future releases, it is still under …

You can see from fig 2 (zoomed in view of fig 1) that the Arduino is taking one sample every 125us from A0. We can calculate the sampling rate as follows: sampling rate = 1/125us = 1/0.000125s = 8000hz To give you a point of comparison, normal audio sampling rates are at least 40kHz. If a sampling rate of 8kHz or less is good enough for your purposes then you …

The Due has 12 analog inputs, each of which can provide 12 bits of resolution (i.e. 4096 different values). By default, the resolution of the readings is set at 10 bits, for compatibility with other Arduino boards. It is possible to change the resolution of the ADC with analogReadResolution ().

- Initializes the AudioZero library by specifying the target sample rate. AudioZero. play - Writes an audio signal read from the SD card to DAC0. Audio File Format. The Audio file to store on the SD card must be in the .wav format with 88200 Hz, 8-bit unsigned PCM mono quality. This type of file can easily be created by software such as audacity. Code
