Re: [info] ESP-EYE DevKIT from Espressif spotted in the wild and i got one :)
Interesting, very interesting indeed. There's some information about the board here too. Most useful post. I have mine untouched so far, cause I don't know how to use it. Now I do :) The link is broken, the information is now here :) I found the correct link eventually :D I only need to know that i...

Re: ESP32 sketches take more space than Arduino Uno
The 2 chips are very very different! The uno is an 8bit device, the ESP32 is a 32bit device. So in a nutshell, an instruction and a simple variable in the uno only takes up 1 or 2 bites of memory, while in the ESP, 1 instruction and one variable takes up 4bytes. About 4x the size Additionally the fu...

Re: Gripes on ESP32/ESP-IDF
Again and again... Not only that your hardware is badly designed. You don't even know how to test it and how to write drivers for it. (And your docs are incomplete too) 2 years on the market and your SPI drivers are still not working. 2 years on the market and you still don't know about all HW issu...

Re: New ESP32-WROVER Ethernet Board
We would love to see the board design and BOM files to be shared though.
Maybe a contantly updated GitHub repo would be useful. If nobody is going to sell it, I would rather put it together myself.

Re: Uart stops working after ASM function call
One thing I just notice is that the chip keeps resetting because of WDT, not with the 10sec countdown (that I previously assumed). So something is happening during the assembly routine. I even modified the code to place the function into IRAM rather than inline, but no change. The only thing left is...

[delete]Uart stops working after ASM function call
[NO LONGER RELEVANT, CAN BE DELETED] Hi All, So I'm sure my issue here is quite new for most people, but I've got nowhere to go to, so here it goes. I'm making an Assembly code function for some RGB mixing with some transparency, and I'm currently testing the code to see if it actually works properl...

Re: ASM code not compiling
Thanks for the feedback. I'm gonna modify it and hope for the best.
Though I'm still not entirely sure what includes should I use when using assembly. I assume specreg.h is enough, because GCC should know all the other registers based on the xtensa toolchain?

ASM code not compiling
Edit: changed topic title I made an assembly based RGB color mixing algorythm, that blends 2 color values (one of which has Alpha component) into a single RGB value based on Alpha color mixing rules. The goal was to make it as lighweight as possible. I tried compiling it by includimg xtensa/corebits...
