Re: ESP32 PICO D4 Power supply

Hi ravi_butani, 1. Can I use 2.8V Supply voltage for all VDD pins without any problem ? (Datasheet suggest 2.3 to 3.6V range except VDD3P3_RTC and I am not using RTC)? No. VDD3P3_RTC should be 3.0 V ~ 3.6 V , see ESP32-PICO-D4 Datasheet V1.7 - "Note that the embedded flash is connected to VDD_SDIO w...

Re: Getting started with ESP32-S

Hello KMM, Can you please help me to get started with? I have installed Ardunio IDE. I am exploring which ESP32-S module to be used. Your suggestion on selecting ESP32-S module is welcome. I am not sure if there are more ESP32-S modules besides that I found in internet and linked in my previous post...

Re: Cant wake up from UART_NUM_1

Hi JosuGZ,

There are limitations to pin selection for wakeup signal, please see the note to function uart_set_wakeup_threshold().
This information is indeed missing in documentation of v3.2.2 you are using, but I see it provided for the latest stable release V3.3.1.

Re: Getting started with ESP32-S

Hi KMM, - Do I have to program my own WiFi stack or BLE stack? No. - Does ESP32-S come preprogrammed with WiFi stack/BLE stack? Some modules, including ESP32-S , come preprogrammed with AT firmware . - How to program/debug the user defined code? See https://docs.espressif.com/projects/esp-idf/en/lat...

Re: ESP32 Unresolved Inclusion on Hello World

Thanks. While I was working on a separate problem, I modified the file CMakeList (to add versioning) and when I rebuilt the project (which forced cmake to recreate the makefile), the #include statements resolved. The problem has not recurred, in this or other projects. Not sure if it's related or n...

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

Like everyone else, better documentation would be a plus. What's wrong with it? Well, it seems like the sort of documentation that was written after the fact and just *barely* describing what things are. Very often functionality is essentially glossed over. What I mean is, descriptions are VERY ter...

Re: ESP32 - JTAG Non-Functional w/ Stock Firmware

1. Can the existing OpenOCD scripts be modified to some how latch the JTAG interface before the user application disables it? I'm looking how to avoid this issue in manufacturing without switching to the UART interface. I'm also concerned with users potentially locking themselves out of the product...
