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...

[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...

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?

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...

Yes there is. It is called WROVER-Kit

Hi Neil - yep, that did the trick. Code posted here for anyone else who might be interested (or for me since I'll probably forget). #include <tcpip_adapter.h> tcpip_adapter_ip_info_t ipInfo; char str[256]; // IP address. tcpip_adapter_get_ip_info(TCPIP_ADAPTER_IF_STA, &ipInfo); sprintf(str, "%x", i...

Actually I revisited this idea in the last couple of days by hard digging into the code, and I thing I figured it out. It's not just hardware but software change as well. For this to work, you will need a WROVER module, delid the module, and modify the hardware with an external logic (2 Flip-flop an...

Hi All, This is mainly called out to the devs. I'm happy to discuss these in PM as I'm having some other flash related questions, before I start my next project. I was checking the SPI FLASH code, and I'm curious, if there is a reason for using the ROM code functions, after user application is boote...

I did not do any software tests yet.
The FT81x can operate with 30MHz SPI clock, well enough for almost everything.
