Re: VS23S010 - 1Mbit SPI/8-bit Parallel Bus SRAM

Perhaps it could be possible to stream the pixels from portC straight to the spi ram. Needs some thinking. Quad SPI or parallel 8bit bus is fast enough to stream the whole display memory in real time.. I remember calculating that 180 fps would be possible. That means that you could use the VS23S as...

Re: VS23S010 - 1Mbit SPI/8-bit Parallel Bus SRAM

What an interesting idea! Just looked it up and there's loads of stuff you could do with ESP8266 and VS23S010 together. Not just games, stuff like home automation displays.. I wonder if I could use it to display info and draw a graph on how my solar panels at the summer house are doing 8-) Anyway, I...

Re: VS23S010 - 1Mbit SPI/8-bit Parallel Bus SRAM

Hi! Experimenting with the VS23S010 default palette (for 256 colors) and a tileset file at VLSI. Got the line length and number of lines correct so that the chroma subcarrier phase is perfect! Also activated the luma trap to remove luma-chroma interference. The colors are just about perfect. Even be...

Re: VS23S010 - 1Mbit SPI/8-bit Parallel Bus SRAM

I know there are some people experimenting with some ideas of these sorts. For more information about VS23S010 video applications, see: http://www.vsdsp-forum.com/phpbb/viewforum.php?f=14. For samples, PM me.

Re: VS23S010 - 1Mbit SPI/8-bit Parallel Bus SRAM

Hi! The blitter (block copy engine) is quite fast, but not blazingly fast. I think that, depending on the size of your frame buffer, it would take something like 5 milliseconds to clear (copy) the picture. It also depends in how many chunks you do it. I'm currently thinking on a software sprite engi...

Re: VS23S010 - 1Mbit SPI/8-bit Parallel Bus SRAM

A bit odd that such a chip exists, but definitely impressive! Thank you! :D The chip exists basically because of my and many of our other employees' and even some members' of the board deep and profound love for computing equipment and games that used television as a display device. Basically all o...

Re: VS23S010 - 1Mbit SPI/8-bit Parallel Bus SRAM

Dear Uze and others, Thank you for your nice messages! Sorry for not keeping up to date with your messages at the Forum, I've been busy writing a tool that allows you to simulate the microcode on the VS23S010 so you can explore various color possibilities. vs23s010 microcode simulator 01.png This to...
