Re: Tutorial Needed: Companion computer reading data

Here is a really simple script that parses the messages inbound from the USB port and prints them to the terminal window. I've added comments so that a newbie such as myself could understand what is happening. Clarifications or criticisms on those descriptions are welcome. import serial, string, re ...

Re: Tutorial Needed: Companion computer reading data

Would you be able to provide a quick description on how to set up that pyopenmv.py script? What script is on the camera and which script is on the computer? -or- It would be nice to have a really simple set of scripts that take a text output from the camera's USB, passes it to a python script on a c...

Re: openMV Firmware Build Instructions

May I suggest an improvement in the Firmware Update dialogue for next time? I interpreted the existing message that the blue LED indicates it is complete with the update. While it flashed blue, it was apparently RED when complete. So, I stared at it for a while as instructed. I think, if the RED LED...

Re: Tutorial Needed: Companion computer reading data

That worked! Next, the numerical output in the IDE Serial Terminal for the clock.fps is around 42 to 44. But, the third-party terminal I'm using (YAT) displays it as 84 - 85. It looks like it is doubling it - but not precisely. Any funny-business happening in the interim? Also, I added a "test" outp...

Tutorial Needed: Companion computer reading data

Is there any tutorial that can demonstrate the code required to enable the OpenMV to send a data stream over a USB to a companion computer (Raspberry Pi, or a PC) running a python script? That script would then consume the data stream and executes a simple task. I need this to work without the IDE. ...

Re: Failed to eject "A:/"! issue and Reset

Fixed! The issue what that my motherboard has a RAMDisk app that was set for drive A. It had nothing to do with OpenMV. The main.py file was being copied there and tricked me into thinking it was the internal disk on the cam. I changed the RAMDisk letter to G: The file is now also running automatica...

Failed to eject "A:/"! issue and Reset

I'm attempting to get a default app running on the camera without it being started via the IDE. My ultimate goal is to establish a data stream from the camera, via a serial connection, to a python script when it is powered up. I intend to do downstream manipulations of that data and want to offload ...
