I developed a GPIO test code by vb2010 express. There is a message when I run the program can not load DLL "aaeonEAPI.dll" . I added x86 "aaeonEAPI.dll" by Add existing item. My Hi-Safe version is "Hi-Safe_v2_20190709_523".
We suggest you to use VB2015 or above to build your code, VB2010 is too old.
