In this video I will be having a closer look at FPGAs and I will do some simple beginners examples with the TinyFPGA BX board. That means we will find out what makes an FPGA so special and also how to program it easily. At the end I will then show you how the required VGA signals looks like and how the TinyFPGA can create them. Let's get started!

How'd you get your head around all these protocols?

@skeezixcodejedi 4 жыл бұрын

_Lolucoca_ vga is ‘just’ analog voltage to control brifgtness for each rgb colour channel, plus careful timing. Not too hard once you read up a bit and ‘click’ .. like again a page or two of codevin C even can expeess it All of these descend from tv in a lot of ways so there is consistency in concept Hdmi is a little trickier as they added some magic and also kept all the docs behind walls. There is a lot to it of you get into it - hdcp and all those security and audi protocols and so on. But if you go to its most basic tv modes and lower resolutions it will permit aimpler operation - its a layered protocol where you establish a link and add on layers of function. At its simplest its nearly just like vga .. you can get like 720p at 60hz as long as your timingis feeding out the pixel values on the right clock. Its digital instead of analog so timing is enormously more precise, hence why fpga is odeal and not a slow chip like most mcu Its also not using single wire for the levels, but differential pair (which many fpga directly support). Fofferential pair is a plus and minus wire and the delta is a pulse. So you need 3 pairs (rgb) and a pair for clock, and theres a little funny credit card chrcksum like thing you do to pad out the bits so it can sync or checksum or someyhing. But thats it - you need a crazy high clock (I forget .. 600MHz or something) and pump out the rgb values in digital. Its just fpga verilog is another step past what normal code is like and historically fpga and verilog books and kits are expensive as hell. But the last uear teat boards and chips came way way down in proce and old books are cheap on the market..

Sweet, I didn't know such small (and easily usable) fpga boards were already available. The Arduino MKR Vidor 4000 seemed promising at first, until I've read that you could only use predefined fpga modules, which prevented me to look into this for a long time. Anyways, these miniature boards should be a lot easier to incorporate into projects in contrast to those Xilinx/Altera dev-boards I used to work with.

Nice introductory video. When you showed the Arty board I nearly fell of my chair while screaming. Not only Xilinx FPGAs are overkill for beginners, the prices are too high, especially the in case of the Digilent dev boards. Then you showed the Lattice FPGA with a completely open source board, and development environment, and I instantly calmed down. I've been using FPGAs for years. Xilinx, Intel, Microsemi, Lattice. Nowadays I'm only using Lattice, it has the right amount of resources, the right price, and an amazingly helpful community. Oh and those Tiny FPGAs are pure gem. When the new EX version comes out I will surely buy it.

GreatScott, very good introduction to tiny FPGA bx .I recalled 5 yrs ago when xillins donated FPGA to my Diploma/secondary engineering school without training .I tried to self-learning through Internet for 3 days and finally gave up !! The price of FPGA and one day professional training are extremely expensive and even the university professors are layman/greenHorn in 2015 ! Today 2020 ,I started to see TinyFpgaBx ,simplified version for Beginners. It was similar to Arduino(invented in 2003 by Italians ,Raspberry Pi invented in UK ) .All are cheap versions for Primary School Toy now.The FPGA will becoming the Secondary School Toy soon ( 2020 many University Engineering Starts to teach U-degree courses, BSc,MSc,Phd ). Thus with Cheap Fpda , future youngsters will create their own computer, microprocessor, CPU, GPU ,SoC,Qbit/quantumComputer...etc. Thanks for your sharing knowledge .

I wonder if it's possible to use an FPGA to do the opposite thing, to capture an VGA signal (i speak about classic VGA, 320*200/256c @70Hz) for example from an old DOS computer, and simply push raw images to a SD card for further processing on a PC. Capturing VGA from classic DOS is actually an issue, most modern capture cards claiming to be able to handle VGA signals are in reality only capable to capture resolutions of 640*480 upwards and only @60Hz instead of the 70Hz DOS uses.

For example, the fomu appears to use a RISC-V softcore and uses the ValentyUSB ip core / github smunaut/ice40-playground/tree/usb/cores/usb ) I'm interested in a structured learning material, that goes from zero fpga knowledge, to designing a USB interface!
