Third Batch Kit V2.61 has problems with the usb communication

Posted 3306 days ago by hottec thank you for your answer. your are possible right with the EMI idea. I also thought at that. i checked it with a wire choke on usb cable as close as possible to detector, but nothing change. :-( here is a screenshot log of rad.py script at a usb port V2.0, the communication lost after 4 counts: Manufacturer: radioactiveathome.org Product: Radiation Detector KIT Status: [0, 153, 19, 0, 0, 3, 0, 0] Realtime clock: 5.017s Counts: 3 counting - please wait... Realtime clock: 8.162s, Counts: 4 29.4046 CPM, 0.171756 uSv/h Corrected 29.4074 CPM, 0.171772+-0.0858778 uSv/h Realtime clock: 11.292s, Counts: 4 21.254 CPM, 0.124147 uSv/h Corrected 21.2555 CPM, 0.124156+-0.0620736 uSv/h Something wrong with getting info from the device!! Closing device Time sleeping for 5 Seconds Trying now to reopen selected device open failed You probably don't have the hard coded hid. Update the hid.device line in this script with one from the enumeration list output above and try again. Have a nice day! |

Posted 3307 days ago by hottec I also found out that usbport v1.1 protokoll the unit works longer with the rad.py script. with usb v2.0 the script works only max. 10 counts The energy control for usb is also on my windows pc switched off . |

Posted 3307 days ago by hottec Hallo, i received the third batch Kit V2.61. I build the kit complete and the unit works fine with display. But there is a big problem with the usb communication. I check the unit or pcb complete with an oszilloscop. Technical with the hardware is all ok. So i began to check the communication for the usb port. The boinc diagram in the map shows also the communication error because there are disconnects. So i check it with the rad.py And the result is that here also after 30-100counts the communication over usb port lost and only a usb disconnect from pc and reconnect brings the communication back with the device. This bug i can reproduce since the last days. in the rad.py script is an reconnect function, but the unit ignore that complete. So who can verify that or can tell me a solution. i think it is a software bug in the avr firmware V2.61! |
