I think fwrite(buf, 1, 512, fi) write an array of 512 bytes, Isn't that right ?.
Is there another way to do this ?.
Regards.

HI,
I have tested the write speed of a SAMSUNG eMMC with two different sketchs. The writing speed of the second
sketch is much lower.

Sketch 1)
https://github.com/espressif/arduino-esp32/blob/master/libraries/SD_MMC/examples/SDMMC_Test/SDMMC_Test.ino
with SD_MMC.setPins(3, 5, 1, 13, 7, 6);
with SD ...

I am trying to integrate an OV5640 camera into an ESP32-S3 using GDMA and the LCD_CAM peripheral.

This is the first attempt and the objective is to verify that the peripheral captures the data from the camera interface and using GDMA writes it to the list buffer.

To check that everything works the ...

Hi,

Does anyone know where I can find a ESP32-S3 LCD_CAM camera example ?.

Regards.

Hi, I am testing examples/SDMMC/SDMMC_Test with those results ("ESP32 Dev Module" 2.0.6) :

1) With SD_MMC.begin() -> Read 1 MByte in 191 mS and Write 1 MByte in 415 mS
Card clock is 20 MHz measured with Oscilloscope

2) With SD_MMC.begin("/sdcard", false, false, 40000, 5) -> Read 1 MByte in 191 mS ...

This works.



#include "WiFi.h"
#include "AsyncUDP.h"
#include "Arduino.h"

const char * ssid = "xxxxxxxxx";
const char * password = "yyyyyyyyyyyyy";

AsyncUDP udp;

IPAddress multicast_address_1 = IPAddress(224, 1, 1, 1);
uint16_t udp_port_1 = 6000;
IPAddress multicast_address_2 = IPAddress(224 ...

With "verbose logging" activated I can see something related to WiFi connection, nothing more.

About AsyncUDP I have tested two AsyncUDP instances and one AsyncUDP instance with two listenMulticast()
without any success.

I don't know what else I can do

Yes, one at a time works perfect.
Yes, the wifi connection is ok.

Thanks but there is a compile error. IP address must be IPAddress type.
From WiFiUdp.h -> uint8_t beginMulticast(IPAddress a, uint16_t p);

Hi,

Is it possible create two instances of WiFiUDP with different multicast address ?.


WiFiUDP Udp;
IPAddress grupo_multicast(224, 1, 1, 10);
int udpport = 6000;
char datain[100];

WiFiUDP Udp_video;
IPAddress grupo_multicast_video(224, 1, 1, 1);
int udpport_video = 6000;
char datain_video[1460 ...
