Re: SD card examples weird results.
Pacondres, I've been doing tests with SDMMC (4 bits) using Arduino and it works perfectly. What type of SD card are you using? There are numerous types, with very varied access speeds. https://github.com/espressif/arduino-esp32/tree/master/libraries/SD_MMC https://www.sdcard.org/developers/sd-standa...

Izadora, Explain in more detail please.izadoraberti wrote: ↑Fri Jun 02, 2023 9:08 pmI have an esp32s3 project that stopped working abruptly.
What did you do on your project?
Did you compile with a new version of IDF? Which was the previous version and which is in use.

Re: esp32 type
Hi Kamran, I suggest starting with the simplest and most common ESP32 on the market. There are a few module manufacturers, but they all use the Espressif Chip. Choose the model that is in the nearest store, for example. https://docs.espressif.com/projects/esp-idf/en/latest/esp32/hw-reference/esp32/g...

Re: Best Frequency Meter ever made with ESP32 - awesome!
Hi Xiaolab, If you don't have another frequency counter or oscilloscope frequency meter, you won't be able to calibrate because you won't have a reference measurement. The ESP32 oscillator has some limitations in the resolution of the generated signal adjustment. So you can't rely on that signal alo...

Re: Best Frequency Meter ever made with ESP32 - awesome!
Hi xialaba,
As I mentioned in the tutorial, the frequency measurement can be calibrated with another frequency meter for calibration!
You can calibrate, changing the variable:
uint32_t sample_time = 1000000;

Re: Best Frequency Meter ever made with ESP32 - awesome!
Ahmet58,
If you did the assembly like the tutorial and used the original code, everything should work perfectly.
If you've done all that and you still have a problem, let me know.
But it looks like you already solved your problem. I'm glad for that.

Re: Best Frequency Meter ever made with ESP32 - awesome!
Ahmet, Unfortunately it is not possible to help you. You have made too many changes which could be the cause of the program malfunctioning! You cannot change GPIO pins arbitrarily. There are rules that are in the documentation. https://www.espressif.com/sites/default/files/documentation/esp32_techni...

Re: Best Frequency Meter ever made with ESP32 - awesome!
Hi Ahmet,
Are you using the same program available here? Did you make any changes?
How are you testing the frequency meter? To test it connect the GPIO 32 (Oscillator) with the GPIO 35 (frequency meter) .
Please answer these questions.

Re: Best Frequency Meter ever made with ESP32 - awesome!
Hi Ahmet,
I don't know this Firebleet, but seeing the characteristics on the site, I can say that the frequency meter can be assembled using it.
