Cypress Maker of the Month: Sree Harsha Angara
At Cypress®, we are all about solving our customers’ problems with our state-of-the-art solutions. We love problems because we are passionate about solutions. The Maker of the Month series recognizes unique projects created by the maker community and their design problems that were solved using Cypress technology. For more information about Cypress’ maker community involvement, check out the rest of our Maker of the Month series and our efforts to empower up-and-coming engineers via the Cypress University Alliance (CUA).
Read the Q&A with Cypress’ Maker of the Month for October 2017, Sree Harsha Angara.
Please provide some background about yourself and your work at Cypress.
I work as an applications engineer on the Cypress PSoC© MCU team. My work involves a mix of solving customer issues, helping architect new solutions using the flexibility of our PSoC technology, and doing full designs for customers with unique problems.
Earlier this year, you worked with Clive (Max) Maxfield of EE Times to develop a PSoC 5 based spatial mic setup. Can you tell us about that project?
Max and I have stayed in touch over the past couple of years through a couple of hobby projects I did in the past and published on EE Times. He pinged me for his new project called the Bodacious Brain project, an intriguing concept with a bunch of LEDs hooked up together to react somewhat like neurons in a brain. We were kicking ideas around and thought about having it react to sound, which made me curious. I put together a simple LED ring/spatial mic setup to make PSoC detect which direction the sound was coming from and act as a trigger to the relevant neuron LED.
How did you help bring the project to life?
I used NeoPixel LED strips from Adafruit which have a convenient LED ring and six attached analog mics under them. I interfaced them to the CY8CKIT-050 kit, a PSoC 5LP based development kit.
Driving NeoPixels is typically processor intensive, but thanks to the Universal Digital Blocks (UDBs) of PSoC, and an existing library (props to Mark Hastings, from CY’s MCU Applications team), it was fairly easy to get them going.
We know you are also working on a project that features Cypress’ CY4343W Wi-Fi and BT/BLE combo SoC. Can you tell us more about that?
This project started off as a pet-peeve of mine – figuring out if some rooms in my house are really colder during certain times of the day. I’m aggregating data from PSoC 4 BLE nodes to a CY4343W chip. Essentially this is a BLE to Wi-Fi bridge, which can capture data from a PSoC 4 sensing the temperature and push it into the cloud.
Although the idea was simple, there are many ways to go about this and so the WICED platform helped smooth through many pains in setting up a MQTT service so I could easily push/pull data to my local laptop.
How has Cypress’ technology helped execute your projects, and what are the benefits you’ve seen with using these technologies?
The Cypress PSoC platform is the first embedded platform I have used extensively and have become accustomed to its flexibility and ease of use. For making quick prototypes, there is no other platform I can think of which comes close to the speed and flexibility. The WICED platform is something I have just begun to scratch the surface of, but the ease-of-use to set up complex tasks like HTTPS servers, MQTT protocols etc. is also very well done.
What is your favorite part about working at Cypress?
Solving customer problems using unique Cypress technology. Working with a great team of fellow engineers is a very close second place.
Are you working on other projects that use Cypress’ technology?
I am currently working on writing fan controller firmware for PSoC 5 in server applications. Other projects I’ve done in the past with PSoC include:
- Digital audio spectrum analyzer with parallel notch-band pass filters
- Building a guitar synthesizer
- Musical note recognition on a small embedded processor
