Re: Investigating program panic from xt_highint4
No, definitely not using any critical section, I also had interrupt watchdog disabled. The intriguing part is that increase instruction cache or introduce some irrelevant (logging) code within the function call will fix the issue. Is there any other reason level 4 interrupt can trigger other than wa...

Investigating program panic from xt_highint4
Hi, I have a program that runs into a weird situation: Main component: ESP32-S3 16MB / No PSRAM, esp-idf 5.1.2, using built-in unity test framework and protobuf-c Description: I have 2 test cases covering a protobuf unpack and a protobuf pack. Both test cases run fine individually. But if I run unpa...

Re: Can we run the ESP32 on 2x AA batteries
I think this way too. Seems the datasheet needs updateWiFive wrote:Gd25 3v flash only rated down to 2.7v? So yes it seems 2.3v is not relevant spec.

Re: Can we run the ESP32 on 2x AA batteries
I’m evaluating PICO-D4 vs D2WD in a 2xAAA project.
In this sense, PICO with bounded GD25 flash (3.3v) is not as good as D2WD with internal 1.8V flash? Although both devices are rated at 2.3-3.6V ?

Antenna matching network on ESP32-PICO-D4
Hi, In the ESP32-Pico-D4 datasheet, the reference schematic shows a matching network after antenna. matching.png But the values are all TBD. I notice that on the many development boards made by Microwavemont the LNA_IN pin is directly connected to the PCB antenna. Currently I have some "W3008C" http...

2 layer PCB
Well, I may need to design a board with ESP32 bare chip (not module) on a 2 layer board. Passing FCC is mandatory. Any pioneer can tell me if it is possible, any rules-of-thumb, or I'd better starting with 4 layers? The project is just at planning stage. It is better to make sure than sorry later. T...

Re: Windows eclipse make wrapper
Hello Angus,
Yes this works perfectly now. Thanks for the patch.
I'm not aware of CDT builtin support for cygpath, maybe it is time to dig into it.

Windows eclipse make wrapper
Under esp-idf\tools\windows, there is a nice Windows eclipse make wrapper, which replaces building command as make $@ V=1 | sed -E "s@ /([a-z])/(.+)/@ \1:/\2/@g" | sed -E "s@-I/([a-z])/(.+)/@-I\1:/\2/@g" | sed -E "s@-L/([a-z])/(.+)/@-L\1:/\2/@g" I understand the purpose is to replace something like ...

Re: ESP-IDF 1.0 Release plan
Any plan about DMA and external RAM?
Would very much like to see SPIFFS but in fact give me flash APIs I can port it in one day.
FAT is good for SDCARD though.

Re: Merry Christmas!
Just raw pixels, so 128x160x2byes= 40960bytes/frame. Should do some compression but I just wanted to push it up before Christmas.
The source code is still ugly. I've put up here:
