Arducam mini 5mp + ESP8266

[labajo]

I'm trying to use an Arducam mini 5MP with the websocket example and it doesn't run for me.

I upload to my esp8266 the following program but It does not run well. https://gist.github.com/labajo/99a2be6098db086430bf927b4275f6a8

I cannot see a special trace to find out the problem.

SPI1 interface Error!

Could you help me?

@Juan There is SPI timing error with 5MP when used in ESP8266, please try our special library released for ESP8266 from https://github.com/ArduCAM/ArduCAM_ESP8266_UNO/tree/master/libraries/ArduCAM

Hello,

I test but in SPI I have 170 not 55

[labajo]

Hi,

with the special library I get the following error:

I had to add the following definitions in the ArduCAM_Mini_OV5642_Capture example:

#define OV5642_CHIPID_HIGH 0x300a
#define OV5642_CHIPID_LOW 0x300b

But they are defined in keywords and ov5642_regs.h

[ArduCAM]

@Juan Sorry for my late reply. It seems that the SPI error and go to the while(1) loop which causes the esp8266 reboot. Please check the following link for the new library. http://www.arducam.com/arducam-esp8266-uno-board-arduino-camera/ http://www.arducam.com/downloads/ESP8266_UNO/ArduCAM_ESP8266_UNO_DS.pdf Let me know if you need more help.

@dmolner Please use the new library for 5MP when used with ESP8266, there is a SPI workaround. http://www.arducam.com/arducam-esp8266-uno-board-arduino-camera/

[labajo]

I get the same error.

The last attempt was made using this library. https://github.com/ArduCAM/ArduCAM_ESP8266_UNO/tree/master/libraries/ArduCAM

I installed the board and I get the same error with the example:

I'm using the following schematic: http://www.arducam.com/arducam-supports-esp8266-arduino-board-wifi-websocket-camera-demo/esp8266_diagram-2/

[mkeyno]

hi every one , is it possible to convert esp-arducam to wifi IP camera can support RTSP or ONVIF protocol ?for streaming the video which protocol is fastest (UDP, TCP, Websocket,.....)? thanks for your reply

[dmolner]

@mkeyno Yes is possible but the problem is because is a serial camera and only can see less 1fps. I test with Ispy and work very good.

[mkeyno]

@dmolner why serial , all OV76xx have SPI interface , I think all @ArduCAM library work with SPI or I2c, check this link http://www.aliexpress.com/item/Hot-OV7670-VGA-Camera-Module-Lens-CMOS-640X480-SCCB-W-I2C-Interface-For-Arduino-Factory-Price/32659604527.html?ws_ab_test=searchweb201556_10,searchweb201602_2_10017_10034_10021_507_10022_10020_10009_10008_10018_10019,searchweb201603_9&btsid=076502c5-c8ba-4066-97ab-3f6677f094e4&smToken=e703a6bc3cab4bbe89391d605b7138b1&smSign=7JFCYIz0%2B5KedbbZR8M1Jg%3D%3D I was hopping can made ip camera with this module and ESP or at least can send the image on motion detection but I dong know how fast this combination will be

[dmolner]

@mkeyno correct! I'm sorry! I confused because use with an ESP8266 and this is a serial module. for this I only have 1 fps.

Sorry!

[labajo]

Have you seen the problem @ArduCAM? Is the schematic right?

[ArduCAM]

@labato, sorry the new example sketches use the new schematic wiring, please check the wiring here; http://www.arducam.com/arducam-esp8266-uno-board-arduino-camera/esp8266-pinout/ The SPI error will enter while(1) loop and eventually cause the watch dog reset.

[AhmadZMQ]

Hi @ArduCam, 1.Here I have got a success to shoot video and their saving in SD card by using "ArduCAM_ESP8266_V2_OV2640_Video2SD" Arduino code provided in the ArduCam library but problem arises is to send the video to the server. 2.Also i want to get control on the video timing as per requirment i.e.10s 20s,40s etc. by pressing external key. How it can be,please suggest the way to solve this issue.Any suggestion from your will be appreciated. Thanks

[mkeyno]

dose anyone success video streaming with OV_7670?

[ArduCAM]

@mehrdad, OV7670 deosn't have buildin JPEG engine, this bandwidth is too large to do video streaming. And OV7670 is quite old and low resolution. Recommend to use OV2640.

[mkeyno]

@ArduCAM I was hoping to build the lowest price IP camera with OV7670 , so as you said I should switch to another module

[ArduCAM]

@mehrdad, how do you build the lowest cost IP camera with OV7670?

[mkeyno]

it was idea base on your repo. long ago I did some effort to directly embed video stream on my website without any third party software or plugin , the result not good as I expected until find what have you done with ESP and OV's modules but as I didn't find any video streaming example with OV7670, I pasted my question here, but as you said I should pay more for my project

[ArduCAM]

@mehrdad, I would like to know more about how do you make IP camera with OV7670 even if you said it is not very good.

[mkeyno]

@ArduCAM it was plan and I didn't make anythings yet but I'm going to use more powerful module or just use OV7670 for motion detection purpose and upload image to the server

[ArduCAM]

@mehrdad, I think at least you have a basic idea how to stream OV7670 video over IP, then I can give you suggesion on that topic. From my experience, you need a powerful hardware to do compression and network streaming.

[edwardcoyne]

I am attempting to interface with a esp32 using the esp8266 codepaths and am encountering the same issue as above where I get 170 back from the SPI initialization test instead of 85 (0x55). Did anyone ever figure out why?

I am using the 0V2640 arducam mini.

[ArduCAM]

@edwardcoyne, current arducam library doesn't support esp32 processor. You have to modify our library to communicate with esp32 yourself.

[edwardcoyne]

ya I had figured as much, If I get it working I will do a PR.

I had just been curious what the cause of the 170 result listed above was to see if it was the same as what was causing my issue. For my case if I switched SPI.setDataMode() to MODE2 or MODE3 it will get the correct result back from that call, I am not certain which it should be though as both seem to work.

I don't have everything working yet but that check passes.
