  • ESP32 memory corruption

    Are you perhaps this poster? - asking that poster for the list I just asked for went nowhere and it was auto-closed.

    I use a ESP32-WROOM-32E-N16 (16 MB SPI flash) with default_16MB.csv partitions table from I need to store multiple files in SPIFFS memory (html for webserver and log file). For that, I use Arduino SPIFFS.h library for ESP32 and it works well until it doesn't work... I get the error : [E][vfs_api.cpp:301] VFSFileImpl(): fopen(/spiffs/log/logFile1.txt) failed. The file exist but I can't open it, and this even if I shutdown the ESP32. I can make it work again only if I reset it with my ESP-Prog board.

  • The Nano ESP32

    That has not been my experience at all as a user. ESPHome is even easier than Arduino and I haven’t touched firmware code in years.

    The price makes a huge difference when you have dozens of them operating which is trivial with a decent hydroponics and smarthome setup. I also have a dozen boards just sitting idle ready to be called up to replace a failed one or use for a new project because they’re so cheap.

    Not to mention the Arduino core is supported officially by ESP32:

    Who actually uses Arduino in production? Everyone just uses modules (for ESP32) or rolls their own using the Arduino board as a reference.

    They've done a good job of hiding the RTOS from you and making most sketches run fine without porting, but you're still running as a task under the RTOS, yielding between loop() calls[1]. This leads to mysterious timing issues if you aren't aware of it[2]

    It doesn't appear that the Arduino core for the Renesas chip is using the RTOS, at least by default -- its main loop is literally doing while (1) { loop(); }, similar to how the AVR core works. [3, 4]

  • exit status 1 error not going away! Pls help
    2 projects | /r/arduino | 21 Jun 2023 may interest you - you need all the files in the same dir, not just the .ino by itself
  • Do you have any idea why this program would not work? [ESP32]

    I copied all the libraries from here:
  • Configure a Raspberry Pi as a USB Device
    7 projects | | 3 Jun 2023
    I would also take a look at esp32 and possibly raspberry pi pico W as well.

    For the esp32 there is this official example of what I think is faking a usb drive:

    Not all ESP32s support USB OTG and I don’t have the correct one here atm to test with. Not sure how much more work would be needed to serve files from sd card.

    You could then use a web server on the esp32 to transfer your files

  • Connecting esp32 to a bluetooth ODB2sensor

    Setup the Software: Next, you'll need to install the appropriate libraries for the ESP32 in your Arduino IDE. The ESP32 Arduino core is what you'll likely need.
  • ESP32-S3 USB frustrates me, you too?
    3 projects | /r/esp32 | 21 May 2023 reports "Hard resetting via RTS pin..." yet I need to press Boot, then press Reset to get the sketch to run. Espressif appears aware of this problem and has no solution.
