A few weeks ago Numato Lab ported our XC9572XL CPLD breakout board to KiCad. Hilipka got one of their assembled boards for free and wrote a review. its quite a nice board, feeld of high quality even included an oscillator … Read more
Jason implemented a frequency counter on an XC9572XL CPLD. It uses a 1Mhz clock to count the duration of the input signal pulse, and shows the output on a 6 digit display. Initially he had to use additional 7400 logic … Read more
voidptr tested the bouncieness of the CPLD development board button and found it to be pretty good. XSVF and SVF files are available to download if you’d like to program the CPLD and try it yourself. that little switch is … Read more
Haley posted build pictures of the XC9572XL CPLD development board from a free PCB Sunday. Thanks for posting a picture of the completed board! Under our new unlimited free PCB program Haley received a coupon code for a new free … Read more
We go through a lot of prototype PCBs, and end up with lots of extras that we’ll never use. Every Sunday we give away a few PCBs from one of our past or future projects, or a related prototype. Our … Read more
Don’t forget to share your current project in the comments or the forum. This week our favorite project gets a free QFP protoboard. Here’s a summary of major developments over the last week: We released XC9572XL and XC2C64A (CoolRunner-II) CPLD … Read more
J. Peterson updated a PDP-11/70 console with an ethernet controller and a CPLD to control the blinking LEDs: I’ve always missed that visual and tactile aspect of computers that’s been lost since the advent of microprocessors. When a console for … Read more
To celebrate the launch of our new CPLD development boards we’re giving away PCBs. Just ask for a CoolRunner-II or XC9572XL dev-board in the comments, if you have a project in mind we’d like to hear about it too. Assembled … Read more
Ever get stuck choosing the right logic chip combination or voltage level translator? Give up the hunt and create your own custom logic chip. CPLDs can give you the logic you need, with the pinout you want, while saving board … Read more
