I reply to myself. It's related to the attenuation, for some reason the default value is not the same in the legacy and new library. I have set 12 db attenuation and I am getting exactly the same value with both libraries: void water_probe_temperature_test_legacy(void *pvParameters) { int adc_raw; E...

Hello, I have the following code that works perfectly fine to read the raw value from a temperature sensor (LM35DZ): #include "driver/adc.h" void water_probe_temperature_test_legacy(void *pvParameters) { int adc_raw; ESP_ERROR_CHECK(adc1_config_width(ADC_WIDTH_BIT_9)); while (1) { adc_raw = adc1_get...

Check the power supply of the target device and also try to reset that.

This was my problem. Thank you.

Ok thanks, I have the numbers now so I will choose the proper option according to final requirements.

I got confused there, of course it’s 1024 variables, thanks. How often do I need to update the variables? Well, as long as I could be able to store them in flash if electricity goes off, I could handle them in RAM, but none of them shold be lost, they are indeed important statistical data the user n...

@nopnop2002, I could do what you suggest with W25 chips but in the ESP32 too, right? I mean they seem to have similar write/erase cycle limits. @ESP_Sprite, this is very clever indeed and very useful for this simple case where there are only 366 values but this sacrifices huge amount of memory space...

It's clear now, I was thinking about that magic value too as an alternative.

Thank you for the help.

Hello, I am migrating one project from PIC to ESP32 and I have the following question regarding data storage. At the moment I use an external memory in the PIC to store some statistical data. The memory is divided in 366 chunks, one per day of the year, where I save what the equipment consumes every...

Ok so let's say I reserve the first 4 bytes of the partition just to check whether it's erased or not. If I understand you correctly, can I assume that if I read those 4 bytes and they're not all 1, then the partition is not erased? Would it be correct something like this? Can I guarantee that if ch...

Hello, I am following this example to implement my own partition and store some statistical data in my project: https://github.com/espressif/esp-idf/blob/a97a7b0962da148669bb333ff1f30bf272946ade/examples/storage/partition_api/partition_ops/main/main.c It's simple enough and it works just fine but I ...
