Our support to Delphi is limited to the provision of the examples. Based on a previous query, the picoStatus.h file is missing from the SDK and so I have attached it to this post.
In addition, we recently had a customer who had some issues with the PicoScope 3000 Delphi example and he kindly provided us with the fixed file - perhaps this may be of use to you. Please note that we have not tested this file.
For the 3204A, please download the latest SDK from our website http://www.picotech.com/software.html
- In Step 1, choose the PicoScope 3204A
- In Step 2, select Software Development Kit R10.1.2.1
- Click the 'Download R10.1.2.1' button when it appears
- Save the PS3000asdk_r10_1_2_1.zip folder to a suitable location on your hard drive and extract the contents - there is a Programmer's Guide contained within.
You will need to use the 3000a files specifically from this SDK for the 3204A.
With regards to your 2nd post, you would most likely need to modify the 3000 Delphi example to work with a 3204A as it uses a different dll and the function names are different. Please refer to the Programmer's Guide and the ps3000Api.h header file if you wish to do this.
I hope this helps.
