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.
