Got it now. Thanks for the clarification. The workaround is not ideal, but it works for now. Please let me know when I can download the fixed version to test it.

To bypass the USBDBG stack... do this. Use the Open Terminal feature to open the serial port your OpenMV Cam is on. Do this without connecting the camera. Then, hit the run button to run the script in the editor window. The script should start outputting text. To see the frame buffer just add a: pr...

Does fritzing have a place to put this or should I like to this? Just download OpenMV3.fzpz file (https://github.com/SingTown/OpenMV-fritzing/blob/master/OpenMV3.fzpz), then use the drop-down menu in the pallette and choose "Import". If you wish to make it a permanent resident of your Fritzing part...

Does OpenMV support the ipproto_sec parameter or is that only for the WiPy?

Thanks Ibrahim. It works now.

I was able to update the firmware to 2.6, but I get this error when I run the WINC Firmware Update Script.

Yeah, the firmware was released earlier but the next IDE will package the v2.6 firmware.

Will the new version of the IDE be released this week?

I've just finished compiling the latest ide binaries with this new firmware. Everything will be released this week.

Does everything mean a new IDE release in conjunction with the 2.6 firmware (released on Dec 4)?

QVGA also need to be fixed. I believe it should read 320x240 instead of 320x120

The LED Control documentation seems to be out of sync with the example code.

That will be great. Would you mind posting back here when it is available? Thanks Ibrahim!

cagiva

However, that doesn't seem to happen (looking at my router's DHCP table and the host name is not set), I think maybe it needs a firmware update. Hi Ibrahim, Thanks for the clarification about that method being specific to the ESP8266. Regarding the hostname, I see the same problem in my router (i.e...

Is there any time frame on when the current OpenMV firmware will be upgraded to the Micropython 1.9.3 release? I'd like to make usage of the wlan.config() method in 1.9.3 release to setup the M7 board hostname instead of using the naked IP address. http://docs.micropython.org/en/latest/esp8266/libra...

cagiva

Is there a fritzing part available for the OpenMV M7?

cagiva

@kwagyeman, pretty much the same components as shown in the above picture. In our case, we'll use to turn a light switch when the camera is operating in the dark hours.

@iabdalkader, I agree. However, it'll be nice to have a shield that is ready for plug-and-play.

cagiva

Are there any plans to develop a Relay Shield for the OpenMV board? Something like the one for the RFDuino.

cagiva

Separate from the capability of processing images; how does the processing power + memory of the M7 board (using the WiFi shield) compares to other boards like the WiPy 2.0 or the Adafruit HUZZAH with ESP8266 WiFi? Has anyone run benchmark tests to compare them?

cagiva

Thanks Ibrahim. The sleep(10) in the original servo_control.py example was too short for my servo. Your snapshot code uses sleep(100) and with that value, it works. You might want to update the servo_control.py example. Anyway, thank you both, for looking into this.

cagiva

The WiFi shield doesn't have P9 listed on it so should I connect the servo signal wire to the RST pin on the WiFi shield; which lines up with P9 on M7 board? The 5V servo jumps a tiny bit when I power up the M7 board, but after that it doesn't respond to the pulse width I send (between 1000-2000us)....

cagiva

I didn't send you my code since I was able to reproduce it with the pixy_uart_emulation.py example.

cagiva

I just tested using the pixy_uart_emulation.py example and the same problem occurred. It refuses to run it (I sent you video as PM). It works fine with smaller .py examples like the helloworld.py. I running with them without the SD card inserted though.

cagiva

Is there a limit on the size of the python script being run from the IDE?

I'm using the OpenMV-7 board and my .py file consist of 198 lines and it's size is ~5KB, but I'm now reaching a point where I have to remove lines to be able to run it from the IDE.

cagiva

If you run /examples/14-WiFi-Shield/mjpeg_streamer.py from the IDE and if you stop it while it is Waiting for connections.., then you cannot eject the M7 from its USB connection. I'm testing it on mac with OSX 10.10.5. The M7 is running with the latest firmware and the WiFi shield.

cagiva

Ibrahim, I'm trying to send my own HTML page, however, I get an exception when I try to use readline or write on the socket. It seems like I can only use the socket.send or socket.recv methods. Although your documentation list the write and read methods. http://docs.openmv.io/library/usocket.html?hi...

cagiva

How does the mjpeg_streamer example generate this HTML page? Can it be overridden with my own or customized?

Are the connections below correct to control one(1) servo using the M7 board with the WiFi shield only?

I used a Windows 10 machine as you suggested, but the LED still continues flashing white after running the Bootloader from the IDE and it completes.

It was pre-ordered back on December 15 directly through your website (purchased by guy.power@nasa.gov) so it's probably one the first boards shipped out.

Uploaded the openmv.dfu file, but the LED still flashes white after the reprogramming dialog completed. I'm pretty much experiencing the same problem/behavior described here: http://forums.openmv.io/viewtopic.php?f=6&t=208#p1144 When you wrote, "DFU is painfully slow." How slow? 5 mins, 1 hour, a day?

The LED is flashing rapidly and it looks like a white color. There is not USD inserted. Thanks.

My M7 module seems to be bricked. I've followed the IDE instructions, but it still doesn't work. It just doesn't enumerate anymore. The LED keeps just flahsing after the LED turned green.

The regulator can supply up to 500mA, so I think it's safe to power the cam and servo from USB power bank (connect the servo to the 3.3v output on the left header). In my case, the servo requires an operating voltage range from 4.8V ~ 6.0V so this will not work for me. http://hitecrcd.com/products/...

cagiva

Sorry Kwabena, I'm not sure I follow. The servo has 3 wires, but are you saying that I need to connect the Vin and GND to an external power source and only use the servo signal wire to control it?

The M7 has one free pin when the WiFi shield is used for servos. Servo channel 3. Or P9.

Great, thanks Kwabena. One more question. Can I power the board and the servo via the USB connector using an external 5V 2A power bank?

cagiva

Hi Ibrahim, Thanks for the clarification. For my project, I just need to control one servo remotely using a web browser, but I'll prefer not to use an additional board to control the servo via UART/I2C. However, I found this post ( http://forums.openmv.io/viewtopic.php?t=159#p769 ) where you indicat...

cagiva

Do I need the servo shield if I want to control just one hitec servo like the HS-85MG? Can I just connect it directly to pins one of the OpenMV board to control it with Servo.py script?

I used sensor.py to simplify things. We do use a different name. It seems that is how MP work. Loads imported modules and cache them in memory, which forces you to hard reset the board if you need test new changes in those modules.
