Re: Waiting for download
I have found when I run into this issue on several other ESP32 kits/boards adding the cap to EN & IO0 solved the problem.bluebirdsoftware wrote: ↑Fri Apr 29, 2022 7:20 amThat is the only one i don't have. It could cause this problem?
It can't hurt to just add it and try.

Re: Waiting for download
What about the 0.1uf cap on IO0 to GND ?bluebirdsoftware wrote: ↑Thu Apr 28, 2022 7:30 amI already have a 10K resistor between IO0 and 3.3v, a 10K resistor between EN and 3.3v and a 0.1uF capacitor between EN and GND.
It still sometimes boots into "download" mode.

Re: ESP32 Wi-Fi ON/OFF Issue
The problem is that the connection was not closed first. The way I got around that issue was every 30 seconds I send a "Heart Beat" character to the web page, when it gets this character it simply sends back a reply. If (on the esp32) side I do not get a reply I close the connection. Likewise on the...

Re: Waiting for download
Make sure you have a 0.1uf cap from EN to GND, and GPIO0 to GND. along with at least a 10k pullup to 3.3v for each pin.

Re: i80_controller_example missing lvgl.h
I am starting fresh. Deleted my prior install. I downloaded the install here (Espressif-IDE-2.4.2-win32.win32.x86_64.zip): https://github.com/espressif/idf-eclipse-plugin/blob/master/docs/EspressifIDE.md Then followed the instructions here. https://github.com/espressif/idf-eclipse-plugin/blob/master...

Re: Need for help to check code for ESP32 with anemometer in Arduino IDE
You didn't specify what module you where using.
Try a different GPIO pin. Maybe your board has a pull down on that pin.
ESP32 SoC has 5 boot strapping pins. They are:
GPIO0 (HIGH during BOOT)
GPIO2 (LOW during BOOT)
GPIO5 (HIGH during BOOT)
GPIO12 (LOW during BOOT)
GPIO15 (HIGH during BOOT)

Re: ESP32 Arduino FreeRTOS Software Timer
I didn't examine it to closely for other issues, but your problem is that your using the variable progState for both timers which is what is causing the problem. You also need to add a delay in loop() or your going to cause the watch dog timer to panic. #include <Arduino.h> #include "freertos/queue....

Re: ESP32-S3 USB host interface to keyboard
I bought 3 books and going through them. Some things are getting clear but getting stuck on ESP-IDF order of things. Thus far (if I understand the order) #1) usb_host_install() #2) usb_host_client_register() #3) usb_host_device_open() #4) usb_host_device_info() #5) usb_host_get_device_descriptor() #...
