Just thought I'd pass on my experience today after purchasing a ADC-20 for an application at work. As usual It was an urgent prototype and I was under pressure.
My thanks to Mark at Pico Tech for resolving the problem.
In summary if your using VB and an ADC-20 or 24 the supplied VB example file does not work.
The example code does run but if a voltage is connected to an analogue input an overflow occurs and the program crashes. There is a variable that is defined incorrectly.
I would recommend contacting pico if you have either of these devices and want to use the example VB sample.
The code is hard programmed to use 24Bit resolotion so be careful if your using the ADC-20 !
A frustrating morning but resolved in the end. But where is the quality check before this software is released ?
The good news is that after resolving he the problem I have used the .NET conversion program and it seems to run fine in visual studio.net.
