This used to work correctly. Now with the ESP32-S3 rev 2 I get a timeout error on compile-and-upload in Arduino IDE 2.3.2. Any ideas? Sketch uses 286037 bytes (8%) of program storage space. Maximum is 3342336 bytes. Global variables use 19056 bytes (5%) of dynamic memory, leaving 308624 bytes for lo...

I'm using Arduino IDE 2.3 on a MacBook Pro laptop 2.3 Ghz Quad Core Intel I7 on Sonoma 14.4.1. My Reflections project has 1 .ino file and 25 .cpp files. It's about 15,000 lines of code in total. Code is here: https://github.com/frankcohen/ReflectionsOS. It takes about 8 minutes to compile the code. ...

This is an experiment to see if a computing device can make sense of gestures made with a person's wrist. It identifies the Fabulous Four Gestures of next, previous, accept, and cancel. It is extensible to train and identify additional gestures. It uses an ESP32 and LIS3DHTR accelerometer. It uses a...

It's not the SD formatting to blame. Further investigation shows openNextFile not returning the file and directory details at the top level - '/' - of the directory. openNextFile works fine in subdirectories. I opened a trouble ticket here: https://www.arduino.cc/reference/en/libraries/sd/opennextfi...

SdFat is an amazing open-source library for Arduino and ESP32 projects to use SD and Nand storage. It's been around since 2009. @greiman does an amazing job, even if SdFat is impossible to maintain. This is my contribution, a recipe for fellow ESP32 enthusiasts needing to format an SD for Fat16 over...

This may be an SD formatting problem, or a hardware problem. I tried the same code on a new board with a new NAND/SD component. It works as expected: Starting SD Card Type: SDSC SD Card Size: 122MB Writing file: /hello.txt File written Writing file: /hello2.txt File written Writing file: /hello3.txt...

Here's the output: Starting SD Card Type: SDSC SD Card Size: 122MB Listing directory: / root = / file = 0 file.path = -end- There are 3 files, no directories. The typical functions of create file for write, read file, delete file, create directory, delete directory all work. It's only openNextFile t...

I'm running the SD example code on an ESP32-S3 dev module and I am getting no return content when using openNextFile(). I am building with Arduino IDE 2.2.1 and ESP32 v 2.0.14. When I call openNextFile() I get no results. Here is the code: #include <Arduino.h> #include "FS.h" #include <LittleFS.h> #...

I figured out 2 problems: The SD library returns random values for file.size() before the file has non-zero contents. I opened a bug report with Espressif at https://github.com/espressif/arduino-esp32/issues/8625. The easy solution is to insert an initial log entry when creating and opening the log ...
