Please check it out, and tell us what you think. Hope everyone is having a great summer! We have a new version PixyMon and firmware that supports color codes. The Pixy Team Posted in: Pixy, Uncategorized New Kickstarter that uses Pixy We can always use help - if you’re a developer of any sort and want to help with the CMUcam5 Pixy project, please send us a note! These projects have been piled up behind this release and they’ve been running far behind schedule, so we’ll be glad to move onto these next tasks and get them moving toward the door. And we’re going to release a face detection algorithm after that. Much of the work is already done - so we’re hoping it will be released soon. Many of you have asked us what’s the status of the GCC-compatible version of the firmware (what we’re calling the “Firmware SDK”). This was in the previous beta release, but it’s also been improved. Saving and loading of onboard Pixy parameters - you can save Pixy’s parameters, including color signatures, on your computer and restore them to your Pixy or even copy them to another Pixy. We’ve also added “SPI with slave select” as an interface option. And we’ve added pan/tilt servo control to the UART and I2C interfaces in addition to the camera brightness and LED controls. These controls have been added and are in the Arduino API.

New features added to the serial interfaces - many of you wanted to be able to control Pixy’s camera brightness/exposure as well as Pixy’s RGB LED from an Arduino. In this firmware version color codes are much improved - more accurate and easier to use. That’s because we simply weren’t happy with it.

Improved implementation of color codes - you may have noticed that our color code implementation never made it out of beta status.
And when it learns an object, the detection accuracy is greatly improved. The new firmware can learn objects with a huge range of color saturation levels. Sometimes it would learn your object, but detection accuracy would be an issue. Sometimes Pixy would complain that the object’s hue wasn’t saturated enough. This feature had room for improvement though. Improved button-teach method - you’ve always been able to teach Pixy an object by pressing the button and holding your object in front of Pixy. It’s super easy… and kinda fun to be honest, but we’re sorta weird in that way. The new firmware uses a simple slider for each color signature - slide it to the left and your color signature will be less inclusive, slide it to the right and your color signature will be more inclusive - everything is adjusted on-the-fly.
There was minimum saturation, hue range and a couple other parameters that you could adjust, but it was unintuitive, and you always needed to re-teach after tweaking things.
Simplified and effective color signature adjustments - another problem with previous firmware versions was the fact that it was somewhat difficult to “tweak” things if Pixy didn’t reliably detect the object you taught it. (The new color filtering algorithm is more computationally expensive too, but we spent lots of time optimizing, and it runs at 50 frames per second like before - yay!) Pixy’s new firmware is more robust, using a more accurate color filtering algorithm. Improved detection accuracy - a weakness of previous firmware versions was false positives, where Pixy detected things that you didn’t intend. It took us a long time, but we’re happy with the results. And we got a significant percentage of you expressing a desire for improved detection accuracy, so that’s just what we did - we paused what we were working on and refocused our efforts like little Pixys tracking lasers, and we rewrote large sections of Pixy’ s firmware with the goal of improving detection accuracy. Way back in July we sent out a survey asking you what you what you wanted us to work on. (If you know of an online retailer that you think would be a good fit for Pixy, please send us a note!) And we’ve added lots of new distributors including distributors in Canada, Australia, China, Japan, Korea, Singapore, Italy, and two in Germany. OK, that’s the big news - some smaller news - we have a Python API for our Linux, Raspberry Pi and BeagleBone Black users. Here’s a video with the highlights of this release: (The Linux version is ready to build from git.).

It’s been awhile, but we have a major new firmware and software release for Pixy (Version 2.0).
