CN0531 no-OS Example Project

See projects/cn0531 (doxygen) for the Doxygen documentation.

The EVAL-CN0531-PMDZ is a precision DAC module designed for applications such as medical instrumentation, test and measurement equipment, industrial control, and scientific research. It features the AD5791, a 20-bit DAC with 1 ppm accuracy and ±1 LSB Integral Non-Linearity (INL). It provides flexibility with support for multiple voltage references and power options, allowing use of onboard or external power supplies and voltage references. The module's compatibility with the SPI Pmod interface enables versatile and precise analog output applications.

Hardware Specifications

Power Supply Requirements

The EVAL-CN0531-PMDZ module requires a power supply that can be configured to use either onboard power converters or external power sources. The onboard converters can generate the necessary voltage levels from a single external input, which is usually supplied by a connected development platform. Alternatively, users can choose to supply power directly through external connections, which can be beneficial for integration into systems with existing power infrastructure. The module's voltage range spans from -5V to +5V, allowing it to be flexible for use in various high-precision applications like scientific instrumentation and industrial control. The high power supply rejection ratio and low operating drift provided by the onboard voltage regulators enhance its stability and precision.

IIO Example

This project is an IIOD demo for the EVAL-CN0531-PMDZ board. The IIO example code initializes the AD5791 DAC over SPI and sets up UART communication for IIO transport. The AD5791 DAC is controlled via IIO descriptors, and the main function manages the setup and execution of the IIO application, utilizing IIO buffers for data transfers with the DAC.

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 DAC and view the output data on a plot.

The No-OS IIO Application together with the AD5791 no-OS driver takes care of all the back-end logic needed to setup the IIO server.

In order to build the IIO project, make sure you have the following configuration in the Makefile:

# remove comment below to enable IIO
IIOD=y
