Re: presoldered ESP32 module

How about one of these? Not sure how well it holds the module as I've never seen one in person. https://www.aliexpress.com/item/ESP32-test-board-batch-burn-fixture-for-ESP32-WROVER-IPEX-Version-ESP-32-ESP-32S-ESP32/32851571106.html John A For prototyping that is just fine - it holds the module in v...

Re: what do you use for timezone management?

We're having the same issue. Unable to find a simple library to convert something like USA/NewYork to posix timezone strings. It seems that bigger systems use the tzdata and full library, but that is too large for ESP32. Could probably parse the tzdata files to extract what we need, and wrap it in a...

Re: Function call backtracing with esp-idf

What you want is not trivial. But, here are some notes which may help: 1. There are no symbols in the .bin file in flash. But, if your running App outputs something that looks like an address, the 'make monitor' part of esp idf will convert it to a symbol and show it. 2. As an alternative to [1], th...

Re: Need 16 MB Flash supported ESP32-WROVER module

We need at least 10000 if they are ready to make ESP32-WROVER module with 16 MB internal flash memory. I thought for 10,000 quantity, Espressif would do it? MOQ 10 reels, @650pc a reel, is 6,500 modules. https://www.espressif.com/sites/default/files/documentation/espressif_products_ordering_informa...

Re: Need 16 MB Flash supported ESP32-WROVER module

Analog Lamb (https://www.analoglamb.com/) are the only ones I know of, at the moment. Even they don't list it on their website (16MB flash WROVER), but can make them.

Re: What would you like to see in The Next Chip?

No more dual-use strapping pins, please. The GPIO2 and GPIO12 vs SD CARD has been a nightmare for us. Overall, messing around with SD CARD issues probably set our project back about 6 months.

Re: autoincreasing build number

Have a look here for how we do it on ESP32: https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/tree/master/vehicle/OVMS.V3/main Look in component.mk and ovms_version.{h,cpp}. We don't use incrementing build numbers (but wouldn't be hard to adapt to that), but instead the output of: git...
