Printing 32 bit data using ESP_LOG or printf

[khu8rt]

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

Code: Untitled.cpp Select all

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_init();

    }

    ESP_ERROR_CHECK(ret);

    ESP_LOGI(TAG, "Starting up!");

    //vSetGPIOlevel(GPIO_NUM_18,1);

    //vSetGPIOlevel(GPIO_NUM_19,1);

    spi_transaction_t spitHandler =  init_spi();

    while(1){

    	sleep(1);



    	uint32_t dataOut = readEMregister(0xc001,spitHandler );



    	ESP_LOGI(TAG, "Register is %04X " ,dataOut );



    }

}

It gives an error that "format '%X' expects argument of type 'unsigned int', but argument 6 has type 'uint32_t' {aka 'long unsigned int'} [-Werror=format=]"

How can i print it correctly, i dont want to split it and then print

Try "%Xl", or "%" PRIx32

Thanks for the hint. %lx works!
