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...

Re: how to get my IP address?

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...

Re: PSRAM as Flash

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...
