I've already tried the GPIO w1ts/w1tc byte permutation trick with a lookup table that some YouTuber made and it's not really fast. It goes up to 38FPS and the tearing is very significant and ugly. It also doesn't utilize DMA, but it's all just bitbanging. I don't think that assembly would help ther...

I heard on some hacker forums Bituni simple ripped that code off of someone else's project. Not sure but this code looks a bit sloppy and it is heavy mixed with Arduino. If you look at I2S technical reference info there are a lot of functionalities that are untouched by most of the code out there. ...

Alright. So, I saw there was a library written by bitluni for VGA where bitluni achieved 580MHz of speed! However, unfortunately for me, unlike for all of other codes, this one he licensed under a ShareAlike license! I wonder if it's somehow possible to do a clean-room implementation (to avoid the l...

I'm looking for an ESP32 board with a USB port that can be used to charge a Li-Po battery while operating the board. The key feature I need is a USB chip that can convert ESP32's USART communication into a HID serial port while providing a virtual CD with a virtual filesystem containing a minimalist...

Hello. I've been looking for a microcontroller fast enough to drive a display without tearing at full 60fps which is also able to run a game engine without having to wait for VBlank. ESP32 has been the best choice. As Bitluni was working on his VGA demo for ESP32 and found out some out of specs I2S ...

There are many boards which have an option for setting the CPU frequency. However, mine which is NODEMCU ESP32-S doesn't. Am I missing on something? Should I set the speed inside of the Arduino sketch?

FYI, if you use the esp-idf SPI driver, the transfer should be done entirely in DMA, freeing up the CPU to do other tasks. We're aware of the 4K limitation in that driver, and I expect a MR that amongst others fixes this limitation to come through within a few days. Wrt 8-bit LCD mode: there used t...

Suggest you look at odroid go and m5stack I've seen M5stack and it sounds promising. However, the equipment is very expensive and I'm not sure if it would work out. Odroid looks very good and it is well done, but I'm concerned regarding legality. Odroid has an Android logo which I'm not sure if it ...

Hello. I've been programming AVR XMEGA and AVR MEGA microcontrollers, but I didn't like some things about them. I've always wanted to make my own alternative to a Sony Ericsson K510i/C510/2705 phone which would have things like a file manager, music player, paint program, programmable apps, etc.. Th...
