Hi, many thanks for your help.
With your tricks the situation is mutch improved, but often I see this:

Hi, I've a problem with espmqtt.
When I send packets with frequency greater than 50Hz I've many of this messages:

Hi,
I've a library in cpp and some libs in c.
Exist a way to compile a mixed project?
I tried to rename the C files in cpp, but I'm submerged from errors.
For me, convert the cpp libs in C is very difficult, but convert C files in cpp is even more difficult.
The interested libs are espmqtt (writed ...

No, I don't call vTaskDelete, because I don't need to delete this task.

Hi, thanks at all for answers.
I'm was wrong because I was putting "static" in header and cpp files.
With "static" only to header file I can compile, but I've a "panic" messages.

Hi, I'm trying to write a class, but I've a compilation error.
Anyone can tell me why?
This is the interested code...

#define LED_H

#include <stdint.h>
#include "freertos/FreeRTOS.h"

Hi, I don't understand :(
In "make menuconfig" I see:

(100) Tick rate (Hz)


But why if I write the line

vTaskDelay(500 / portTICK_PERIOD_MS);


the task work fine and with:

vTaskDelay(ledMode / portTICK_PERIOD_MS);


the task doesn't work though ledMode is equal to 500?

Can you explain ...

Hi, I've a strange problem with vTaskDelay().
This is the code:
main.c

void app_main()
{
ledInit();

esp_err_t err = nvs_flash_init();

printf("Hello!!!\n");
}


led.h

#ifndef LED_H
#define LED_H

Hi, I tried to connect an Arduino configured to slave and data sent from esp is received.

After 3 days of tests, I haven't solved.
The latest test that I made is to write a little sketch for arduino reduced to minimum as possible and when I've seen that it work on arduino, I'had translate it for esp-idf.

Arduino sketch (it works fine):

#include <SPI.h>

#define RST_PIN 9 ...
