System Crash when using ADC40 with usb adaptor

Post by Oliver Daniell » Wed Oct 05, 2005 1:34 pm

I have recently written some software to read data from the ADC-40. When the ADC40 is running without any voltage input i get a system crash with the following error when the computer restarts.

BCCode : 10000050 BCP1 : FEF69800 BCP2 : 00000000 BCP3 : AACD55A3
BCP4 : 00000000 OSVer : 5_1_2600 SP : 2_0 Product : 256_1

The problem seems to be random however as yet it has not occured when using the PicoScope software.

The problem only occurs when i am not inputting any voltage to the ADC40. Another side effect is that when there is no voltage input to the ADC40 the reading fluctuates form +5 - 5v.

The drivers i am using are a few days old as is the ADC40

I am using the adc10_get_value() method to read from the ADC40.

Hello Oliver,

We have recently updated the ADC11 USB drivers which should correct this problem.

Please download them from
