ESP-32 WROVER KIT what are the role of the LED ? How to make D7 blinks ? #2365
Comments
D7 is DATA BIT 7 for the Camera interface. RGB LEDs are defined further down: Where in the documentation did you see that GPIO35 is connected to LED? |
I think the root cause is that the red power LED on the board has component name D7. (Diode 7.) Unfortunately the D7 power LED and the D7 on the camera connector are different D7s. As @me-no-dev indicates, the RGB LED is controllable via GPIOs in software. |
@me-no-dev you see this D7 directly on the board |
@projectgus so the only one drivable led is the RGB isn't it ? As for today there is nowhere in any documentation, that precise the rôle of each LED: D5 to D12 The documentation guide should be updated to include these informations. |
Functionality of those leds is shown in the schematic of the board. While I can understand the need for better silk screen maybe, general rule of thumb is that unmarked LEDs are unaccessible. You can guess the functionality of the LEDS (if schematic is not provided) by their position. D9-12 for example are right next to the FTDI chip and D7 is close to the power. |
Admitting this rule, a table which explicit the rôle of each of these unaccessible LED would be welcomed and also a note that warns the user to not confuse the D7 (or any other Dx) on the silkscreen and the other D7. I don't know who is in charge of the wrover kit tutorial documentation, it's juste one table and one phrase. Please notice, that as of today, the only documentations of the Wrover Kit is the pdf schematic above, and the getting started guide there is nothing else, no description document or datasheet, nor bill of material or gerber files. I guess that it is because it is still a new product... |
Hi @Navis-Raven, |
Hi @SDS-Emb, this is to hide the older version of documents in main menu, so orphan files are not reported, while keeping them available for linking in other places. These files are accessible under Previous Versions of ESP32 Modules and Boards |
Included ESP-WROVER-KIT V4.1 in documenation: Added 'Get Started' guide and updated 'HW Reference'. Closes espressif/esp-idf#2363. Closes espressif/esp-idf#2365. See merge request idf/esp-idf!3161
Environment
Problem Description
The ESP-WROVER-KIT starter guide describe that D7 (which is a LED on the board) can be toggled by switching GPIO35 but it does not work
https://github.com/espressif/esp-idf/blob/master/docs/en/get-started/get-started-wrover-kit.rst
Expected Behavior
I think that it is a documentation issue. The documentation does not precise what are the role the LED. And whatever, the LED 7 should blinks if it is GPIO35 according to the documentation.
Furthemore there is no blinky code example on the web (except for the RGB LED)
Actual Behavior
Nothing happens
