AD400x no-OS Example Project on ZED and SDP-K1

Product Details The AD4000/AD4001/AD4002/AD4003/AD4020 family of evaluation boards enable quick, simplified evaluation of the AD4000 family of 16-/18-/20-bit, precision successive approx-imation register (SAR) analog-to-digital converters (ADCs).

The AD4000/AD4001/AD4002/AD4003/AD4020 are low power, 16-bit/18-bit/20-bit, precision SAR ADCs that offer high performance with throughputs up to 2 MSPS (1.8 MSPS for the AD4020). The evaluation board demonstrates the performance of the AD4000/AD4001/AD4002/AD4003/AD4020 family of ADCs and provides a simplified interface for a variety of system applications.

No-OS Supported Examples

Basic example

This example prints sample data out to the uart.

Here is an example on how see the sample data of the basic example using zedboard:

minicom -b 115200 -D /dev/ttyACM1 -C ~/serial.dat
make run
cat ~/serial.dat | grep  ADC | cut -d ‘ ‘ -f 2 > ~/plot.dat
echo “set terminal jpeg; set output ‘~/o.jpeg’;plot ‘~/plot.dat’ with lines” | gnuplot

IIO example

This project is actually a IIOD demo for EVAL-AD400X device. The project launches a IIOD server on the board so that the user may connect to it via an IIO client. Using IIO-Oscilloscope, the user can configure the ADC and view the measured data on a plot.

If you are not familiar with ADI IIO Application, please take a look at: IIO No-OS

If you are not familiar with ADI IIO-Oscilloscope Client, please take a look at: IIO Oscilloscope

The No-OS IIO Application together with the No-OS IIO AD400X driver take care of all the back-end logic needed to setup the IIO server.

The read buffer is used for storing the burst data which shall be retrieved by any LibIIO client.
