FPGA based Mandlebrot set generator

Mandlebrot Set Generator As I said in my last post, I implemented a Mandlebrot set generator in my STM32. Even though it was running at 64MHz, generating the set took a fair bit of time, slow enough to not even maximise the fully available SDRAM capacity at the time. At this point, I decided to […]

SDRAM + VGA + FPGA = SPI Addressable graphics card!

Having already written an SDRAM based VGA controller, I’ve finally got round to writing a simple SPI module that allows my STM32F0 discovery board to write to the SDRAM during blanking. In the video above, I hadn’t implemented a “busy” pin so my STM32F0 was spamming pixels regardless of whether there was blanking or not. […]

FPGA VGA and SDRAM

The magic 3! FPGAs being the coolest components out there, with VGA being the standard for all graphics and finally; SDRAM, the base of all synchronous memories. These past few days, I’ve been designing an FPGA based SDRAM controller as I’ve got an SDRAM chip on my FPGA development board which I haven’t yet interfaced to. Instead […]

uHMCU – Alpha 0.1

After a pretty large redesign, I can now safely say that the uHMCU is in alpha stage! I’ve ironed out most of the bugs for my USART module and can now both send and receive data. I tested it up to 115200 baud with the USB <-> USART bridge on my FPGA board and after […]

Goodluckbuy soon-to-be HSEL Glass

Goodluckbuy, about the corniest sounding website ever? Nope! It is instead, another Aliexpress-esque market place where you can purchase cool gadgets from. My first purchase off their however was a relatively pricey one ~£70 and consisted of an attachable eye display in an all in one package! Since the inception of Google Glass, I’ve thought of […]

STM32F4 SPI VGA Controller

Well it seems all of my projects recently have been based around my LCD monitor! I think its just because its fun to actually be able to see the outcome of your work as opposed to just seeing a statement change in debug or an LED flash. This isn’t actually an original idea of mine, I […]
