Fresh hacks every day
[Andrew] is trying to buckle down and hammer out his PhD project but was surprised by the sorry state of the configuration options for his FPGA/ARM dev board. Using JTAG was painfully slow, so he studied the datasheet to see if there was another way. It turns out the Xilinx FPGA he’s using does have a slave serial mode so … Read the rest
[Thomas’] love affair with Commodore computers spans well over 30 years, and not too long ago he decided to recreate one of his favorite Commodore offerings, the PET. As we have seen with similar undertakings, this sort of project is no easy task, but [Thomas] seems to be making his way along nicely.
Using a Xilinx Spartan-6 FPGA … Read the rest
Here’s an intense hack that lets [Matt Evans] play Game Boy Advanced on a larger LCD monitor. He didn’t take the easy way out during any step of the process.
He’s using an FPGA to translate the LCD signals from the GBA hardware into a 1280×960 picture that is then pushed to the large monitor. But did he use … Read the rest
[ Jack Gassett] is working on an FPGA shield for the Arduino. At first the idea of this expansion board seemed a little silly. But [Jack] mentions that the FPGA board can be quite useful for adding higher-order electronic complexity like HDMI capabilities to an Arduino. We’re not totally sold on the idea, but he’s not making the board … Read the rest
Okay, now we’re beginning to feel a bit like [Alice]. This tutorial shows you how to simulate VHDL code. This code is intended to run on an FPGA and includes a software-only version of the AVR 8-bit microcontroller core. Essentially, you’ll simulate VHDL code that simulates AVR hardware. Wrap your mind around that!
The code is intended to run … Read the rest
[Phil] over at Retroleum has cobbled together a clean, well put together laptop based entirely around a Zilog Z80 microprocessor and a pair of Spartan II FPGAs. These FPGAs allow him to reduce the number of devices on his board, and therefore cut his production cost as well as device size. He even managed to integrate a salvaged PSOne screen. … Read the rest
[Chris Fenton] spent a year and a half constructing a 1/10th scale Cray-1 reproduction. The famous supercomputer was meticulously modelled in a field programmable gate array for a “nearly cycle-accurate” reproduction. [Chris'] hardware of choice for the project is a Xilinx Spartan-3E 1600 development board, using 75-80% of the available resources. The finished product runs at 33 MHz and … Read the rest
