Thanks for the hint. %lx works!

I am reading a data from a device, the data is 32bit long and i want to print it using ESP_LOG. Here is my code void app_main(void) { esp_err_t ret = nvs_flash_init(); if (ret == ESP_ERR_NVS_NO_FREE_PAGES || ret == ESP_ERR_NVS_NEW_VERSION_FOUND) { ESP_ERROR_CHECK(nvs_flash_erase()); ret = nvs_flash_...

Thanks for the response, the issue was the esp logs that i was printing before and after each transaction, removing them solved the issue.

I am using ESP32 C3 Wroom 02 Dev kit to communicate to V9203 chip using SPI. I already tested the communication using Raspberry pi 3 and it works. For a successul write opertaion, i have to send 3 * 32bit frames. but the ESP32 takes quite a long time between each SPI frame. Between the first two fra...

Great, thanks it worked!

I have ESP32-C3-wroom-02 dev kit and i want to use a GPIO to set it high or low based on my requirement. I tried the following code, but the GPIO18 is not changing #include <stdio.h> #include "driver/gpio.h" #include "freertos/FreeRTOS.h" #include "freertos/task.h" #include <unistd.h> #define LED_PI...

There's multiple ways to do that; if all you want to do is store a float then nvs seems to be the most applicable. Nvs has examples in the esp-idf directory if you need them. I believe the Arduino equivalent would be the 'preferences' library. Thanks, i was able to write data and read after power l...

it is quad SPI flash It is rated for about 10000 cycles. It is not appropriate for storing highly volatile data. It will likely work for most uses, even to the point of storing somewhat ephemeral data like authentication cookies, particularly if you use a write method with wear leveling (eg fatfs o...

Hello, I am new to espressif and bought a devkit based on esp32 with 4MB embedded flash. i have some questions. What type of flash is included in the SOC? What are the maximum number of write cycles for this flash? I cannot find example code on how to access this flash, i want to store a float value...
