Here are the steps to setup SUB-20 as a replacement for obsolete U2C-12 boards

1) Install latest SUB-20 software package (see viewtopic.php?f=2&t=3)
2) Update the SUB-20 firmware to the latest one(viewtopic.php?f=2&t=31#p69 )
3) Verify that everything works properly i.e. launch subtool and try to communicate with SUB-20 board
4) Rename and unzip the attached i2cbrdg.zip.
5) Rename the original i2cbrdg.dll to i2cbrdg_orig.dll in the system32 folder
6) Copy the attached i2cbrdg.dll to the system32 folder

Run your U2C application. If during U2C_OpenDevice no SUB-20 units can be found this dll will load original i2cbrdg_orig.dll and use it for any future calls.

This is an INF file and DLLs for native U2C Devices based on WinUSB and running on 32 and 64 bit platforms

Below is a correspondence between U2C Ports and SUB-20 GPIO: For instance: U2C Port B0 - SUB-20 GPIO8
