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. […]


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 […]

Enter the uHMCU…

It’s been a while since I’ve sat down to do some proper VHDL but today (after MASSIVE advances with the Phobass these past few days), I’ve decided to write a miniature version of the HMCU. I say miniature in the lightest sense. Features: MISC architecture featuring 9 Instructions 16bit processing capability (22bit program word length) […]
