ESP32-S3: multi devices with usb host library

Hello, I would like to connect a keyboard and mouse over USB HID on my ESP32-S3. To connect the two devices at the same times, I will use an USB hub. From the USB Host Library documentation : https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/api-reference/peripherals/usb_host.html it say...

ESP32-S3: problem with usb_host_interface_claim() on IDF v5.0

Hello, I'm try to write my own HID host driver. This work fine on ESP-IDF v4.4. I get my keyboard or mouse event. But on ESP-IDF v5.0, usb_host_interface_claim doesn't work. This is the backtrace : abort() was called at PC 0x4037723f on core 0 0x4037723f: lock_acquire_generic at C:/espressif_5/esp-i...

Re: VGA driver from ESP32 S3

Thanks for your response ESP_Sprite

I use ESP32-S3-WROOM-1-N8R8 module (from ESP32-S3-DevKitC-1-N8R8).

The two frame buffer are stored in octal PS RAM : 640*480@60Hz@8bits (300 ko / FB)

Do you known, the max bandwidth with octal PS RAM ?

Re: ESP32S2 - Quad SPI Slave / QPI Example + Notes

Hello KWolfe81,

I would like to use Quad SPI in slave mode on my ESP32 S3. I'm interesting by your example. But your link is down, can you reload it ?

Thanks

List files store in SPIFFS

Hello,

I would like to list files store in SPIFFS partition. In Arduino world, I do this :

Code: Select all

Dir dir = SPIFFS.openDir("");
while (dir.next()) {
    Serial.print(dir.fileName());
    File f = dir.openFile("r");
    Serial.println(f.size());
}
But with IDF, I don’t known how to list these files.
