The ESP32 in 4 bit (MMC) mode can read >17MB/s and write nearly 10MB/s. You just have to put the driver into HS (high speed) mode. I am not sure...

It should also be noted that the problem with no video with the original Rossumur version appeared (for me) when switching from core v1.0.5 to v1.0.6. The video hangs in...

The sketch above to determine the revision of the ESP32 chip does not compile under Arduino IDE v1.8.13 using any version of the ESP32 core. I tried v1.0.1 through v1.0.6....

Yeah, your code compiles just fine and I don't get the warning. I will remove and re-install 1.8.13 as that is the only thing I have not tried. I did...

Well, I take that back... just going from core 1.0.5 to 1.0.6 and recompiling the exact same code causes the same error. I had to erase the flash again, and...

Yes, by core I mean the core selected by the board manager. Apparently the problem occurs just going from v1.0.5 to v1.0.6. Why not use a higher multiplier than 4x...

Right, typically the number of phases is correlated to the color clock you are using. Each phase is a color and the luminosity gives you the shades of that color....

A HEX byte is *always* represented as two ASCII characters. Whoever maintains this code should use Wiki, Google, Yahoo, or perhaps jump into a time machine to see that this...

2.0 is really unusable until we can have "data" folders that can be stored on a ESP device.
