Hi @loboris,

Thank you for this great component and comprehensive demo.
As usual with your applications I got it up and running in no time.
This should be a great solution for battery powered projects.

I think the most comprehensive summary of places were to buy ESP32 modules is http://esp32.net/#Purchasing

Love this site for wealth of other well organized ESP32 information

This particular example is rather to demonstrate how to trigger interrupts depending on signal change on an input. But it also contains a "simple" check for GPIO level in line: https://github.com/espressif/esp-idf/blob/v2.0-rc2/examples/peripherals/gpio/main/gpio_test.c#L55 The actual check is done ...

It works now, thank you!! It did require connection of VCC to the JTAG for successful connection, and then ready to go! Thank you for update :D I see elsewhere on internet that people connect VCC as well for Segger J-link. This is not needed for Olimex ARM-USB-OCD-H. Both ESP32 DevKitC and ARM-USB-...

I'm using a ESP-WROOM-32. Does the change above mean that I should make any changes to my board... Yes, this change is recommended for ESP-WROOM-32 as well The guidelines says that this change is regarding pin 9, but this is not the same as pin 9 on the ESP-WROOM-32, right? Right, the RC circuit sh...

Flashing over JTAG is now implemented in official openocd-esp32 distribution - https://github.com/espressif/openocd-es ... 878cfa5dfe

HI justinmreina, You are clearly almost there. I am not sure about wiring: 1. I would not connect 3.3V between ESP32 and Segger J-Link. ESP32 should be powered through own USB 2. From the pictures you posted it looks like one of lines is connected to GPIO27 while GPIO12 is not connected Please see b...

Hi linuxpaul, Thanks a lot for the tip that the "pkg-config" is the single "troublemaker"! In fact I was looking for a workflow to compile OpenOCD for Windows. Here is what I have just successfully tested for MSYS2 / Windows 7: Building OpenOCD from sources on Windows platform ======================...

I am happy to see you are progressing! Configuration files have changed with latest release of OpenOCD and "jtag_debugging_for_esp32_en.pdf v1.0" is not updated to reflect these changes. Regarding the error log, it looks like communication speed or wiring problem: Info : Reduced speed from 20000 kHz...

This is great news
Thank you for update!
