SPI1 interface Error! (OV2640 + ESP8266 Nano V2) #284

Open weston0718 opened 6 years ago

weston0718 commented 6 years ago

I am using ArduCAM (OV2640) library with a ESP8266 Nano V2 to run a capture example code (following the instruction, http://www.arducam.com/knowledge-base/esp8266-nano-v2-tutorial/), but it was not workable.

The wrong messgae is shown as below.

How can I fix the problem? Thank you.

@weston0718 Hi, Don't worry, On ESP8266 Nano V2 platform, The SPI CS is GPIO2.Please check your harware connection firstly. Does your camera can work fine on other platform ( such as arduino uno)?

weston0718 commented 6 years ago

@UCTRONICS

Thanks for your reply, but I do not fully understand what you mean. May you elaborate a bit more? Thanks. There is my hardware connection between ArduCAM-Mini and ESP8266 Nano V2.

Arducam-Mini-2MP ESP8266 Nano V2 CS ---> CS MOSI ---> MOSI MISO ---> MISO SCK ---> SCK GND ---> GND VCC ---> VCC SDA ---> SDA SCL ---> SCL

I have a similar issue, could you please help me : As you can see in the picture below, I have a Wemos ( ESP8266 + MEGA ), but on my ESP, I do not have D7 (GPIO 13), nor D5 (GPIO 14) Please, help !

@izaoui Hi, Does your board has SPI interface and I2c interface?

izaoui commented 6 years ago

Hi, thank you for your response, I have a panel named "ICSP" ( screen below, but I'm not sure this is what your are talking about ) Seems this panel is more from Mega, not from ESP8266 Let me know please, FYI, the card link below https://www.banggood.com/fr/Wemos-Mega-WiFi-R3-ATmega2560ESP8266-32Mb-Memory-USB-TTL-CH340G-Compatible-For-Arduino-Mega-p-1205437.html?cur_warehouse=CN img_0434 Best regards, Iliès

Please, help ...

supprot commented 6 years ago

@izaoui We don't have your board. You should look up the schematic diagram of the board firstly. Regards.

@weston0718 @UCTRONICS I recently bought this same board from Amazon, and am having the same problem. I did change my sketch to use GPIO2 const int CS = 2; but still get the same error in the serial console as @weston0718 initially reported:

ArduCAM Start!
SPI1 interface Error!

Also worth noting, I verified my memorysaver.h has the correct board defined.

Has anyone gotten this board working?

UCTRONICS commented 6 years ago

@jbishop129

We have tested ArduCAM_ESP8266_Nano_V2_Capture demo with ESP8266 Nano V2 board. We attached some pictures for you. You can test your camera on Arduino UNO platform to check if the camera can work fine. Can you attach us some pictures for your hardware connection?

jbishop129 commented 6 years ago

Thanks for the quick response. Please see below, using the "ArduCAM_ESP8266_OV2640_Capture" example. Also like to point out that in your screenshot, your example name is ArduCAMESP8266Nano.... which makes me think it is a different or newer sketch. Can you please provide the complete sketch?

I would like to wire up to a generic Arduino, however the sketch does not make it clear (to me anyway) the pin-out. So, I don't really have a place to begin.

@jbishop129

We have updated our ArduCAM ESP8266 UNO board. You should remove the old version and download the new version following http://www.arducam.com/knowledge-base/esp8266-nano-v2-tutorial/ You can preview the demo from https://github.com/ArduCAM/ArduCAM_ESP8266_UNO/blob/master/libraries/ArduCAM/examples/examples/ESP8266/ArduCAM_ESP8266_Nano_V2_Capture/ArduCAM_ESP8266_Nano_V2_Capture.ino

jbishop129 commented 6 years ago

Thanks @UCTRONICS , something seems to be flaky with either my board, or my Arduino IDE: I removed all my existing ArduCAM config, and started fresh with your instructions above, and uploaded the Nano_V2_Capture example sketch. To my surprise, I was able to access the video stream when connecting to it with my phone! First time!

Next step, I wanted to connect it to my WiFi network, so I changed over to int wifiType = 0; and filled in my info under the //Station mode... section. Uploaded the sketch again, and I'm back to square one with the SPI1 interface error! message. Then I tried again to upload the original example (after closing Arduino IDE and starting back up, disconnecting and reconnecting the board), and still with the error.

I'm going to try again tomorrow on a different PC with a fresh Arduino IDE install. I really want to get this board working! I'll report back tomorrow, thanks for the help so far. Now to shift gears and get some dinner started :)

UCTRONICS commented 6 years ago

@jbishop129 OK, Any problems,please feel free to contact me. Maybe your hardware connection is defective ,you can try reconnect your camera to the nano V2 board.

jbishop129 commented 6 years ago

@UCTRONICS EDIT: I got it to work reliably, by commenting out the section which checks for the SPI bus on startup, such as:

/*
  //Check if the ArduCAM SPI bus is OK
  myCAM.write_reg(ARDUCHIP_TEST1, 0x55);
  temp = myCAM.read_reg(ARDUCHIP_TEST1);
  if (temp != 0x55) {
    Serial.println(F("SPI1 interface Error!"));
    while (1);
  }
*/

Not sure why this board fails to check the SPI bus correctly, but apparently it is in fact working. Any tips on how I may resolve this? I am now able to connect it to my WiFi network and stream the video via browser.

original post: I am at a loss on this one. I went ahead and installed a fresh Arduino IDE on a new PC, loaded up the board from the .json file, rebooted (just to be safe), loaded up the example "...._Nano_V2_Capture" sketch, and just as before, SPI1 interface error! Very frustrating, as I did get it to work once last night, but never again. By all accounts, this seems to be a defective board. I'll pursue replacement with the seller and try again. Will report back when I get a replacement... thank you for your assistance so far!
