Build an AM Radio Transmitter from a CPLD

has been playing around with the CPLD-like parts of a PSoC. Which is to say, he’s been implementing simple logic functions “in hardware” in software. And after… 277 more words


Programmable Logic: Build Yourself a CPLD Module

A Complex Programmable Logic Device (CPLD) is a great piece of hardware to have in your repertoire. As its name implies, you can program these chips to serve the logic functions you need. 1,764 more words

Hackaday Prize Entry: An Open Source Graphics Card

For last year’s Hackaday Prize, tried to build a video card for microcontrollers and headless Linux systems. It was only 640×480 resolution VGA, but the entire project was designed around a CPLD communicating with a microcontroller over SPI. 210 more words

Hackaday Prize Entry: Very, Very Small Logic

Despite the existence of FPGAs and CPLDs, there’s still a necessity for very small programmable logic devices. GALs, PALs, and other old tech just won’t cut it, though, and so we are left with a new generation of programmable devices that aren’t microcontrollers or CPUs. 219 more words

Programmable Logic

I’ve been interested in programmable logic for a while now. Recently, I bought a couple of cheap dev boards; One Altera MAX II EPM240 (available on ebay for less than $10AU delivered to Australia); 507 more words


New Part Day: Modern PALs

Back in the bad old days, if you needed a little bit of custom logic you would whip out a tiny chip known as a PAL. 259 more words

CPLD Fun - SPI Master data transmitter

So today, I had my first lecture on VHDL. I’m not a massive fan of learning to code through lectures without doing but we have labs on it later in the year. 415 more words
