I want my device to appear as Universal Serial Bus controller and I want to be able to communicate with it via my custom PC application not via COM port.

I think here may happen some complication. Apparently you want simple serial communication but don't want the device to appear as a COM port ...

Ok it turns out that when using https://github.com/espressif/esp-idf/tree/v5.5/examples/peripherals/usb/device/tusb_serial_device
example, the device appears both on Ports as USB Serial device and also appears as USB Composite Device in Universal Serial Bus controllers in device manager.

Few ...

4. Are there any ESP32-S3 examples where I could test USB and not USB Serial implementation if that even makes sense?


Sure: https://github.com/espressif/esp-idf/tree/master/examples/peripherals/usb/device


I see all those examples and none of them seem to be what I am looking for hence I ...

Hello. I have been into MCU'S and programming for a while now, but never really used USB much. I have finally picked up a few ESP32-S3 Development boards and decided to try USB. The example I am currently running:

Thanks for all the suggestions.

I will also make a post to sonar community regarding this, perhaps they can shed some light as this seems to be false warning in this particular case.

As have been suggested, a correct way to declare a task is as following:



static void HELLO_TASK(void *param ...

@mbratch

It is a simple static declaration of a freertos task function in my main.c. The full code is as following (my main.c):




#include <stdio.h>
#include <inttypes.h>
#include "sdkconfig.h"
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "esp_chip_info.h"
#include "esp ...

FreeRTOS has a macro with casting built in, `pdMS_TO_TICKS`. I use this all the time instead of literally putting the conversion in as `1000/period_in_ms`. So I would write:

vTaskDelay(pdMS_TO_TICKS(portTICK_PERIOD_MS));

Have you tried that and does it get rid of the warning?
The only caveat ...

It is still not clear to me how can I avoid this warning.

I have tried to declare my task with const void* param as shown below:


static void HELLO_TASK(const void *param)
{
UNUSED(param);
for (;;)
{
printf("This is normal message1 without ANSI color code \n");
vTaskDelay(1000 / portTICK ...

We use SonarLint to analyze the code. The default way to create a simple FreeRTOS task is as shown below:

static void HELLO_TASK(void *param)
{
UNUSED(param);
for (;;)
{
printf("This is normal message1 without ANSI color code \n");
vTaskDelay(1000 / portTICK_PERIOD_MS);
}
}

However ...

Hey. We have an ESP32 running a webserver (both in AP and station mode is supported). On the ESP32 we currently have index.html, scripts.js and styles.css that are stored in the flash memory.

Our webserver is scaling up quite rapidly, we are constantly adding more and more functions and it has ...
