esp32 wroom and camera ov7670

[Gaston1980]

Hi to all, Im using the camera ov7670 with the esp32 wroom kit and finally I'm able to get the frame data in 320x240 *2 framebytes.....153600 bytes I got in frame....and now the question...how do I send this frame to uart? I'm using ESP_LOGI to send it to terminal and is tooooo slowww.
I only got an ftdi board connected to uart2 of the esp32 board but I'm unable to send each char of the frame, how can I get those bytes and send it to uart2?
Maybe is the dumbest question but right now I'm unable to see it
Regards

You'd use the uart driver. Don't expect great performance, though: if you have good hardware, you may be able to get it working at 4Mbaud, meaning a frame rate of ((4000000/10)/153600)=2.6fps.

Hi @ESP_Sprite thanks for your reply, I'm trying to understand and play with the camera ov7670 and I was able to get it working in the esp32 wroom 32E board, now I 'm trying to get out those bytes in the frame buffer. For this I create a task in which I use the uart driver to send to cutecom the data to then get the image. At frist I was thinking in sending the bytes but a lot of garbage is send it too like this:

Code: Select all

+<break x 002>
+<break x 002>

i guess is the problem of the cutecom......
I tried to use:

Code: Select all

ESP_LOG_BUFFER_HEXDUMP(TAG,frame,153600,ESP_LOG_DEBUG);

But the watchdog reset the output, and here's the question_

1) how can I do the hexdump without been rest by the watchdog?

this is the task I used:

Code: Select all

void send_data(void *arg)
{
    while (1) {
    ESP_LOG_BUFFER_HEXDUMP(TAG,frame,153600,ESP_LOG_DEBUG);
    vTaskDelay(1 / portTICK_PERIOD_MS);
    } 
}

I read about the watchdog reset but I guess it can't be used in this case due to the hexdump function.

This appears to be real data, not garbage.


>how can I do the hexdump without been rest by the watchdog?

Disable task watchdog timer using menuconfig.

Thanks nopnop2002 for your help, I was able to make the hexdump but...(theres always a but....) is there a way to save this dump to txt because I'm unable to check the first lines of the hexdump ( missed 9000 lines).
Thanks again
Gastón

> is there a way to save this dump to txt

Code: Select all

idf.py flash monitor -p /dev/ttyUSB0 > hoge.txt

[Gaston1980]

thanks for ur help nopnop2002 and ESP_Sprite I was able to do it. A final question about the port been used to do the dump, how do I close it? I tried Ctrl + C but that didn't work.
Thanks again
Cheers

nopnop2002 thanks, I tried and is not working. I need to restart vscode to be able to use again the port.
