Re: Problemi with SPI...

Yes, I know, but I asked it because if on Arduino I execute only SPI.begin(); // Init SPI bus mfrc522.PCD_Init(); // Init MFRC522 I already see the signal in MISO pin. On ESP32 the signal is always flat and then I tought that can be a wrong initialization of SPI bus and not a problem into the code. ...

Problem with SPI...

Hi, I'm trying to use MFCRC522 whith this code: https://github.com/blmhemu/ESP32-MFRC522 . It doesn't work, but after a lot of tests without satisfaction, I've tried to analyze the signal with the osccilloscope. The result is that the signals are flat in all SPI configured pins. So, I've wired the M...

Pardon, I understanding.
The problem is not created from this loop but from another task.

[SOLVED]Simple while freeze loop...

Hi, I've a question... Why this code freeze the loop? printf("Start\n"); while(1) //while (!gpio_get_level(CLOSESWITCH)) { printf("%d\n", curServoPos); //curServoPos -= changeDelta; /*ledc_set_duty(LEDC_HIGH_SPEED_MODE, LEDC_CHANNEL_0, curServoPos); ledc_update_duty(LEDC_HIGH_SPEED_MODE, LEDC_CHANNE...

Re: Setting connection data in c++

I didn't want to stop you. It's just that you can find more (esp32) examples written in C instead of C++.
Yes, I know, but I think that to learn C++ maybe is better starting from desktop applications.
I have to learn a lot again.

Re: Setting connection data in c++

Many thanks for answer.
Btw. embedded programming is not a good start to learn C++.
Infact, now I've decided to develop my project in pure C :D

Hi, I'm studying C++ and I'm trying to write a class to connect to AP using esp-idf. During compilation, I've these errors: $ make CXX build/main/wificonn.o In file included from /home/stefano/Programs/ESP32/.dev-tools/esp-idf/components/esp32/include/esp_timer.h:44:0, from /home/stefano/Programs/ES...
