Cypress Launches $5 ARM Dev Board

CY8CKIT-049-41XX Dev Kit

We do love new development boards at Hackaday, and it’s always nice to see companies providing cheap tools for their products. For those needing a cheap ARM solution, Cypress has just released a PSoC based board that’ll cost you less than $5.

There’s two main ICs on the development board. The first is the target: an ARM Cortex M0+ based PSoC 4 MCU. The second is a CY7C65211 USB bridge. This device is communicates with the target’s built in bootloader for flashing code.

The bridge can also be configured to talk UART, GPIO, I2C or SPI.  If you need a USB to serial converter, this part of the board could be worth $5 alone.

The PSoC 4 target happens to be similar to the one our own [Bil Herd] used in his Introduction to PSoC video. If you’re looking to get into PSoC, [Bil] provides a good introduction to what makes these chips unique, and how to get started.

TIQ Probe is More Logical than Most

 

We had [Mark] on our “dance card” for people to find at Maker Faire. But before we could track him down he bumped into us holding the TIQ Probe in one hand and a testing box in the other. TIQ is conceived in the form factor of a traditional logic probe but thanks to the Cypress PSoC 5LP inside it’s much, much smarter than the decades-old bench tools. Sure, it can tell you if that uC pin is a 1 or a 0, but it can also detect what type of signal it’s probing and has built-in protection for over-voltage.

The point of the tool is to bridge the gap between things which would be measured with a DMM and those measured with a proper Oscilloscope. We think he did a pretty good job of including the things that someone just starting out without expensive bench equipment might want. For instance, you can set it to trigger on common data protocols like i2c, and use the probe itself as a rudimentary pulse generator.

The bulk of the details on the probe can be found on its Kickstarter page (which has just a few days left). You may also be interested in his company page. We’re curious about the insides of the test rig he was hauling around. [Mark] is a regular reader so hopefully he’ll leave a comment below with the details of that black box.

The Rube-Goldberg of car audio

[Anthony Pray] had his car stereo stolen. When thinking about replacing it he realized the he and his wife never used it for anything other than an Auxiliary connection to play songs from their cellphones. So instead of buying a head unit he pulled an unused home audio amplifier out of a dark corner of his house and wired it to the car speakers. Problem solved, except that the under-dash installation meant the only volume control is on the phone playing the audio. He decided to build a wireless audio controller that would let him send commands to the phone without quite as much distraction from the road.

The device you see above is his creation. What a beauty. But seriously, it’s so random and hacked together how can you not love it? And, it works!

The frame is made from plastic coat hangers, and the wheel is an old RC control knob. There’s even a play/pause feature built from the clicking properties of a retractable ball-point pen. A Cypress PSoC board reads the knob and pen positions, then pushes commands via a Bluetooth module in order to control the phone. He recorded a testing video (after the break) which gives you a better look at the functionality of this setup. [Read more...]
