Re: ESP32-PICO-V3-ZERO Datasheet | 技术规格书

The link has been updated with a different datasheet. It shares the same version - 1.0 - but is more recent, dated November 3rd. It is now "ESP32­-PICO-­V3-­ZERO (ACK)", but this is a very different module with just 3 GPIO led out. Are these the same product? Different? What's the status of ESP32­-P...

Re: Where to buy the core DevKitC V4 without ESP

There's ESP-PROG and ESP32-DevkitS. The latter looks perfect for you.

Re: RTC fast memory usage and slow memory size

That 4k is longer reserved in IDF: https://github.com/espressif/esp-idf/commit/ef10c2576ff14afa033ef22105406399abc570af You can use RTC_DATA_ATTR macro to place there or access memory at 0x50000000, eg. https://github.com/espressif/esp-idf/blob/178b122c145c19e94ac896197a3a4a9d379cd618/components/ulp...

Re: ULP ADC read help

Not directly possible. You'll either need to include all variations of ADC instruction in the ULP program and have the ULP jump to the correct one based on a variable that can be changed by the SoC, or change the ULP program when you want to change the ADC channel. You could try updating just the on...

Re: debug logging from adc_set_init_code (on main thread) causing an abort because it thinks it calls from an ISR

Looks like it's because adc_set_init_code, which includes a ESP_LOGD, is being called in a critical section from adc1_get_raw.

Comment out that line or reduce logging level, and consider filing an issue on GitHub.

Re: getting a WDT error that doesn't make sense

Is there a busy loop in Buzzer and other wdt-triggering tasks? Perhaps in some function common to them all?
Post Buzzer task here?

Re: esp_https_ota is complaining about "invalid size"

As an aside, can someone confirm that the second OTA's offset is 0x20000 because it has to be aligned on a multiple of 0x1000? 0x200000, aligned to 0x10000 after the end of the previous partition. I think you're seeing this error because flash is erased in 4K (SPI_FLASH_SEC_SIZE) sectors and your a...
