AD-PQMON-SL Kit no-OS Example Project
Overview
The AD-PQMON-SL provides a complete software and hardware platform for prototyping and evaluating high performance class S polyphase energy quality monitors. The design incorporates the ADE9430 high performance, polyphase energy monitoring IC that has an advanced metrology feature set (total and fundamental active power, volt amperes reactive (VAR), volt amperes (VA), watthour, VAR hour, VA hour, total and fundamental IRMS and VRMS, power factor) and the MAX32650 ultralow power ARM cortex-M4 with FPU-based microcontroller with 3 MB flash and 1 MB SRAM. The ADE9430 enables accurate energy monitoring over a wide dynamic range through its superior analog performance and digital signal processing (DSP) core. The ADE9430 simplifies the implementation and certification of energy and power quality monitoring systems by providing tight integration of acquisition and calculation engines. This solution can be used on a 3-phase system or up to three single-phase systems.
Preliminary requirements
The licensed software library that works in conjunction with the ADE9430 IC can be obtained from here.
After obtaining the libraries, the following files need to be added to the project:
pqlib_dir
| libadi_pqlib_cm4_gcc.a
└───include
| ade9430.h
| adi_pqlib_debug.h
| adi_pqlib_error.h
| adi_pqlib_memory.h
| adi_pqlib_profile.h
| adi_pqlib_version.h
| adi_pqlib.h
└───config
└───adi_pqlib_cfg.h
It can be integrated into the project by defining the PQLIB_PATH to point
to the pqlib_dir path.
Choose interface
The firmware application can communicate with clients via several interfaces.
In order to use the preferred connection type, set INTERFACE to the
desired value:
INTERFACE=usb(Default value)INTERFACE=serial(Used for 485 communication. Half-duplex communication must be handled by user)INTERFACE=ethernet_t1l(Used for communication over T1L)INTERFACE=ethernet(Used for standard Ethernet communication via W5500 controller)
Note
In case one builds firmware multiple times with different interfaces, make
sure to delete the build directory before the new compilation.
Note
For T1L connection the default ip for the device is 192.168.97.40. For
network configuration on client side, use the following steps: network
configuration steps.
Note
For standard Ethernet connection, the default IP for the device is
192.168.1.110. Make sure your network environment is configured
appropriately to communicate with this IP address.
Build and run
The project is based on a MAX32650 microcontroller. It can be built and run by running the following script:
# remove build directory make reset # select platform export PLATFORM=maxim # select controller type export TARGET=max32650 # select interface export INTERFACE=usb # build and flash the code make PQLIB_PATH=<path_to_library> run
The iio_info of the device should look like the following:
IIO context has 3 attributes:
uri: serial:/dev/ttyACM0,115200,8n1n
serial,port: /dev/ttyACM0
serial,description: MAX32650 CDC-ACM
IIO context has 1 device:
