In some of my past articles on the PowerQuad,  we examined some common signal processing operations (IIR BiQuad and the Fast Fourier Transform) and then showed  how to use the PowerQuad  DSP engine to accelerate the computations.        The matrix engine in the PowerQuad can be used to perform common matrix and vector operations to free the M33 CPU(s) to perform other tasks in parallel.     In general, the matrix engine is limited to a maximum size of 16x16 size (or 256 operations).

The i.MX RT series bridges the simplicity of MCUs with the complexity of applications processors into a hybrid portfolio offering ease-of-use designed to address the growing consumer demand for enhanced user experiences. Offering high-performance – up to 1Ghz – modernized HMI capabilities, expanded memory options, and advanced security, the i.MX RT series can help you push the boundaries of what is possible in the IoT – even on price-conscious designs.  The possibilities are endless: Imagine using the i.MX RT in clothing technology to help manage airflow; and maybe that device interacts with others such as smartwatches to actively cool the body. Similarly, imagine adding IoT capabilities to gaming devices for an enhanced gaming experience.

There is a wiki page describing the way hot create the SCR entry for the SDK component here.

It is referenced from the MCUX SDK wiki space.

Feel free to put your comments and questions directly on the wiki page. 

I wanted to take a quick break from some of the PowerQuad articles to show off a neat library that works well with the LPC55S69.      One of the design features of the Mini-Monkey experiment was a 240x240 Pixel IPS display.     I feel that the LPC55S69 is a good fit for small, low active power embedded graphics applications.  It has quite a bit of internal SRAM to store a framebuffer and has lots of processing power to composite a scene on a small display.  In some of my previous articles,  we use this display to show static images as well as displaying time series data from a built in MEMs microphone.   I ran across a twitter user “The Performance Whisper” who had recently released a lightweight and efficient  animated GIF decoder.

NXP has released the newest versions of MCUXpresso SDK, IDE, Configuration Tools, and Secure Provisioning Tool. In addition to new product support, you will find these updates and enhanced features in the new releases.

Today, NXP announced an update to the eIQ™ Machine Learning Software Development Environment, becoming the first semiconductor vendor to implement the Glow neural network compiler for vision-, sensor- and voice-based ML applications. This new neural network compiler technology delivers unprecedented inferencing performance for NXP’s i.MX RT series of crossover MCUs.

I had some design updates for “Rev B” of my Mini-Monkey design that I wanted to get in the "queue" for testing.  For the next revision, I wanted to try PCB:NG for the board fabrication and assembly.  PCB:NG is an “on-demand” PCB assembly service focused on turnkey prototypes via simple a web interface.    The pricing looked attractive and it appeared that the Mini-Monkey fit within their standard design rules.    The Mini-Monkey design uses an NXP LPC55S69 microcontroller that is in a 0.5mm pitch VFBGA98 package.   NXP offers guidance on how to use this device with low-cost design rules and I thought this would be a great test for PCB:NG.   I had success with Rev A at Macrofab and thought I would give PCB:NG a shot.

All the contributions are open source and are part of the Tock project, available on github.

In my last article, we examined a common time domain filter called the Biquad and how it could be computed using the LPC55S69 PowerQuad engine.        We will now turn our attention to another powerful component of the PowerQuad, the “Transform Engine”.      The PowerQuad transform engine can compute a Fast Fourier Transform (FFT) in both a power and time efficient manner leaving your main CPU cores to handle other tasks.  

In my last article,   we starting discussing the PowerQuad engine in the LPC55S69 as well as the concept of data in the “time domain”.    Using the Mini-Monkey board, we showed the function of collecting a bucket of data over time.     I chose to use a microphone as a data source as it is easy to visualize and understand.      You can now easily imagine replacing the microphone with *anything* that changes over time.     In this article we are going to look at some common algorithms for processing data in the time domain.  In particular, we will look at the “Dual Biquad IIR” engine in the LPC55S69 PowerQuad. An IIR biquad is a commonly used building block as it is possible to configure the filter for many common filtering use cases.   This article is not intended to review all of the DSP theory behind IIR filter implementations but I do want to highlight some key points and the PowerQuad implementation.

PyeIQ is written on top of eIQ ML Software Development Environment and provides a set of Python classes allowing the user to run Machine Learning applications in a simplified and efficient way without spending time on cross-compilations, deployments, or reading extensive guides.

The internal clock frequency of Kinetis chips varies due to manufacturing tolerances. A trim value is programmed into the chips to compensate for this variance and make the slow bus frequency uniform between chips.

For some inexplicable reason, this trim value is not active during debug mode. This makes developing serial and CAN applications very difficult, as the baud rates which are set are not the baud rates which are achieved. To make matters worse, if I understand the documentation correctly, the baud rate in debug mode is different from the baud rate in normal mode.

Built into the LPC55S69 is a powerful coprocessor called the “PowerQuad”.   In this article we are going to introduce the PowerQuad and some interesting use cases.   Over the next several weeks we will look at using some of the different processing elements in the PowerQuad using the “Mini-Monkey” board.   

Hi All,

This is Mini Drum Pad build in with IMXRT1015. Also it has AFE shield board which is used for capsense buttons.

IMX RT is, using SAI to play the audio file at 16KHZ. I have created 12 samples (.wav file) and the raw data is stored in the music file. Based on the capsense button press triggering the sound effect.

Speaker I used is from Boat, it has internal battery so only thing required is to feed the Aux input from IMXRT EVK.

I felt that, button sense over I2C bit slow due to that having the limitation of playing the music as faster. Anyway its just demonstration of my concept.

Have you recently been sceptical of using a contact-based access system in your office or a public place? This trait is a major concern in most places for a valid reason. An access surface in a public place is used by many individuals, which makes it a potential source for contracting the deadly Covid 19 virus. Taking this into account, iWave Systems, a leading embedded solutions provider, has successfully demonstrated an alternative solution using facial recognition technology. The solution helps customers with a zero-contact access application by using individuals' faces to authorize access to a commercial/industrial space, home/office, transportation, banking, and Government sites.

The Mini-Monkey is now officially “out the door”.   I just sent the files to Macrofab and can’t wait to see the result.   Before I talk a bit about Macrofab, we will look at what going to get built. A few weeks ago, I introduced a design based upon the LPC55S69 in the 7mm VFBGA98.   The goal was to show that this compact package can be used with low cost PCB/Assembly service without having to use the more expensive build specifications. The Mini-Monkey board will also be used to show off some of the neat capabilities of the PowerQuad DSP engine in future design blogs.
