Installing a running

Run setup_USB_I2C.exe It unpacks self into USB-I2C.exe and Microchip MCP2221DLL-M-dotNet4.dll files , that are necessary for run on 32 or 64bit Windows. (For older OS than Windows 7, i.e. Vista or XP SP3 maybe you also need to install USB driver

http://www.microchip.com/wwwproducts/Devices.aspx?product=MCP2221#documentation

or/and .NET library). The program is built direct in C# of "Visual Studio 13 community" that is used for education. Software is not registered and so setup program need to be enabled maybe more times, although no malware hides inside program

Then run USB_I2C.exe file:

You need to connect the computer and the MCP2221 USB/I2C bridge by USB cable with mini-B connector. Next you connect bridge and slave ICs by I2C bus(SCL,SDA,GND, 3 or 5V Power if missing) Bridge works as a master, and if other master IC is connected yet, probably you need to disconnect it. You can choose "Device" from upper menu strip . If you click DRV10983 :

You can control a motor either directly by PWM or by analog input voltage or, if „Over ride“ is marked, you control it through I2C by scrollbar . If "EEPROM ENABLE" is chosen, you can tune DRV10983 parameters in runtime, and write them into EEPROM or into *.csv file by „EEPROM block actions“ box. After switch on DIAGRAM button some values shows you in time.
