I also sometimes get this error: OSError: [Errno 16] Device or resource busy: '/dev/pyboard' I don't know why I get it, maybe as mentioned dhylands, this happens because I access the pyboard from two terminals for plotting data via matplotlib and bokeh(my custom web interface). In most cases it work...

Dear Pythoncoder and Bryan,

Thank you very much for you support. I hope that this version (with linear ccd sensor) will give much better resolution than my previous attempt. If I make it working as I intended, maybe I will commercialize it .

Best,

Dear @pythoncoder, Thank you very much for examining and correcting my code and providing a clear explanation of my mistakes. Data, gathered by the updated code, you can see in the attached files: 1. Sensor was covered by a box. 2. A half-covered sensor. The shape of the line (covered sensor) this t...

Hello everybody, For my detector I was advised by blmorris to use one of the AMS (formerly TAOS) linear sensors. I decided to go with TSL 1410R ( http://ams.com/eng/Products/Light-Sensors/Linear-Array-Sensors/TSL1410R ). Unfortunately, I couldn't find any information how to read data from this senso...

Dear dhylands,

Thank you so much for your help! Now it works (at least with python 3) !

Dear pythoncoder, Thank you very much for your suggestion but unfortunately I get a different outcome. pb_get_data.py: def get_data(): data= [i for i in range(10)] return data print(get_data()) pc_read_data.py: import pyboard a = pybaord.execfile('pb_get_data.py') print(a) When I run in the terminal...

Dear pythoncoder and dhylands, Thank you very much for your replies. I am still having problems with transferring data from pyboard to PC. Here is a simplified version of my pb_get_data.py: def get_data(): data= [i for i in range(10)] return data get_data() This is my pc_read_data.py which is run on...

Hello All, I am going to build a web interface to interact with my sensor and a problem I stumbled upon is how to transfer data from the pyboard to PC. My sensor generates about 1300 values that are stored in a list so I am wondering if there is a way how to pass the whole list from the pyboard to P...

Dear Bryan, Thank you very much for taking time and looking through the documentations of the linear ccd sensors. Also, I would like to thank you for pointing out to less sophisticated sensors, since I still have to figure out how to connect and read data from the sensor, the simpler - the better. I...

Hello, I hope you all are doing well today. I made a detector using Pyboard and some sensors but unfortunately the resolution that my detector generates is quite low, so I decided to improve that by using a more complex sensor. I am wondering if it is possible to connect and read the data from a lin...
