Re: WROOM date?

Hi urbanze,

Suggest contacting sales@espressif.com with your requirement, and they can make sure you get appropriate WROOM modules.

Re: ESP Thermal considerations

I would like to add that it happened in a few other EV boards. And the current usually drops to around 100-150mA. In one of them manual reset helped. This is all quite unusual. I'm not denying this is happening to you, it's just that noone else has reported this kind of systemic problem. I have thr...

Re: skipping incompatible libraries

Hi zampano, One more question (sorry for all the back and forth). Can you please post the output from this: xtensa-esp32-elf-objdump -f /opt/esp-idf-sdk/components/esp32/lib/libcore.a Also, I don't know if this will work, but can you please try: /usr/bin/../lib/gcc/xtensa-esp32-elf/5.2.0/../../../.....

Re: Is it safe to combine examples of stable and latest version?

Hi TeaElse, Is it safe to combine examples from stable with the ones from latest or are there too many dependencies within the many components? Using an older example project with a newer ESP-IDF (same major version) should always be OK. This is because we do Semantic Versioning so we try not to mak...

Re: lwip upgradation

Yes, this is a substantial undertaking. ESP-LWIP project has a number of patches which are not in the upstream LWIP. You can diff the upstream 2.0.3 release with the current ESP-LWIP HEAD commit to see the differences. Updating to 100% upstream LWIP without these patches will probably result in some...

Re: Can LuaJIT be build for ESP32?

Yes, not fast enough, and troublesome(I like ffi) to bind C function Unfortunately "easy" ffi type functionality requires dynamic shared library loading. This is something we also don't have on ESP32 at the moment, any C code needs to be compiled and statically linked into the "final" binary. That ...

Re: Can LuaJIT be build for ESP32?

It's probably technically possible to make LuaJIT run on an ESP32, although the extra memory overhead of Just In Time compilation may stretch the available IRAM for doing useful things with the natively compiled Lua routines. It would still need a lot of complex porting work as the "JIT" part of Lua...

Re: ESP Thermal considerations

- By did not turn on I meant the 1st of option of unresponsiveness from UART(the com was recognized by the computer due to the FT231X component), - Just to make sure I 100% understand: you open a serial program at 115200bps, reset the ESP32, and see absolutely no output at all from the UART? It see...

Re: Make menuconfig generate local headers

On Windows with MINGW32 the easiest way to make builds faster is actually to move to CMake and not use MINGW32: https://docs.espressif.com/projects/esp-idf/en/latest/get-started-cmake/ To add ccache to mingw32, do "pacman -S ccache" and then set the toolchain prefix to "ccache xtensa-esp32-elf-" in ...

Re: Esp32 connected to 1-wire overheats and burns board

Hi slluch,

There still isn't enough information in your post for someone to help you. You mention a number of pin names but you haven't mentioned the model number of the GPS device you are using, so noone can help you. A good picture of your setup will help a lot.
