Re: Low latency game emulation on SPI LCD

I'm not sure I fully understand what this means, but it certainly seems interesting! Are you saying you built a driver to essentially increase the refresh rate and response time of a SPI based display? How would anyone else implement this into their project? Yes, your interpretation is correct. I'v...

Low latency game emulation on SPI LCD

My SmartGear/RPi project is starting to take shape. In this video, I'm running on a RPi0W with Shea Silverman's PiPlay Portable board to provide the buttons and sound circuit (I'm using a SteelSeries:Free for input since it allowed me to hold my cell phone in one hand to film it): https://www.youtub...

Re: URGENT SCREEN HELP! Need help choosing the right screen variant

(bought the Adafruit pitft 3.5 first, which sucked :cry: ) Which one of these should i buy and would have the least trouble with? (these are the only ones i can get shipped to Finla...

Re: [Guide] ili9341 SPI TFT Screen on Retropie

Yes and no... I have a couple of ili9341 screens but nothing set up that works... That's the nice part of using my emulator. You don't need to set anything up. The only thing you need is to do is connect the display and controls and build pigpio with EMBEDDED_IN_VM defined in pigpio.c (oh - and SDL...

Re: [Guide] ili9341 SPI TFT Screen on Retropie

wow that sounds awesome! I just added ASCII configuration file parsing to allow customization for any hardware. It can read GPIO pins directly for game inputs (no Linux drivers needed) or gamepads/keyboard. Do you have a RPi with a ili9341 LCD connected? I can share the executable if you'd like to ...

Re: [Guide] ili9341 SPI TFT Screen on Retropie

I'm working on a custom game emulator project which uses all of my own code and talks directly to the SPI TFT. Many games are able to run at 60fps and all games run with considerably less input lag and no display tearing compared to the retropie+fbtft+fbcp setup. The code currently uses smart buffer...
