Hello,

When I follow the user guide of DLPC4422 GUI, trying to load the "DLPC4422.projector" file, It says "Error: could not load DeVaSys adapter DLL: USBI2CIO.DLL". How to solve this problem?

    Hello Luyang,

    Thanks for the question on E2E.

    Are you trying to communicate with the EVM via USB or via I2C using a DeVaSys module?

    If you check the EVM User's Guide, section 2.4 indicates how to configure the DLPC4422 GUI to communicate via USB or via I2C using a Devasys board.  

    If you are trying to use USB, please select Edit- >Preferences->Communications -> USB Interfaces -> USB -> OK. 

    If you are trying to use I2C via Devasys board, select Edit -> Preferences -> Communications -> I2C Interfaces -> DeVaSys -> OK.  Please make sure the Devasys driver is installed from the devasys website.

    If you are trying to connect via I2C using a Devasys module,  this E2E Post discusses some additional details about using I2C.  

    If you have any further questions ,please let us know.

    Regards,

    Gary
