AD5592R/AD5593R/LM75 no-OS Example Project

Overview

The Analog Devices Active Learning Module - Low Speed Mixed Signal Playground or ADALM-LSMSPG is a board containing two ADC-DAC chips and a temperature sensor.

Both the AD5592R and AD5593R are 8-channel, 12-bit configurable ADC/DAC IC with the primary difference being that one (AD5592R) uses an SPI for communications and the other (AD5593R) uses IIC.

Additionally, the ADALM-LSMSPG board also utilizes an LM75 temperature sensor with a 9-bit Delta-Sigma ADC.

Applications

Control and Monitoring General purpose analog and digital inputs/outputs

Hardware Specifications

The ADALM-LSMSPG board is powered entirely by the 3v3 supply coming from the connected carrier board.

No-OS Build Setup

Please see the Build Command section below for the no_os_build.py flow, or https://wiki.analog.com/resources/no-os/build for more information.

No-OS Supported Examples

The initialization data used in the example is taken out from: Project Common Data Path.

The macros used in Common Data Path are defined in platform specific files found in Project Platform Configuration Path

IIO Example

The IIO example initializes and configures AD5592R, AD5593R and LM75 using the Industrial I/O (IIO) framework. It showcases the setup of the mentioned devices via their corresponding drivers to reach operational mode. Because it is IIO enabled, real-time data acquisition and processing of ADC data is efficiently transferred from device to host client application.

Demo Hardware

Build Setup

Available variants: curvetrace_example, iio. Available boards: max32665fthr. Replace --variant / --board accordingly.

export MAXIM_LIBRARIES=</path/to/MaximSDK/Libraries>

cd no-OS

# build the project (iio example on the max32665fthr board)
python tools/scripts/no_os_build.py build \
   --project adalm-lsmspg --variant iio --board max32665fthr

# build and flash (requires a connected debug probe)
python tools/scripts/no_os_build.py build \
   --project adalm-lsmspg --variant iio --board max32665fthr \
   --probe openocd --flash

Connection Setup

  1. Use a USB Type A to mini-B cable to Connect the Max32665 FTHR board to the feather connector header of the adalm-lsmspg board.

  2. The adalm-lsmspg board will be powered up and the red HEARTBEAT LED should start blinking a pre-defined pattern similar to a plane's beacon.

  3. A serial device should appear in the device manager of the operating system.

  4. You can use the various IIO software applications like IIO-Oscilloscope to connect and communicate to the ADALM-LSMSPG board.
