7. n e For OpenSprinkler 1 x and 2 0 you need to install USBtinyISP driver e For OpenSprinkler 2 1 you need to install USBasp driver In general you do not need to run any executable file from the driver installation folder Instead plug in a USB cable to OpenSprinkler for OpenSprinkler 2 1 and above press and hold pushbutton B2 while plugging in a USB cable then release B2 within 2 seconds and let Windows detect the device It will report that driver is not found Next go to Device Manager identify the USB device USBtiny or USBasp right click the on the device and select Update Driver then select Browser My Computer Page 13 for Driver Software and provide the path to the driver files folder This should allow you to successfully install the driver Windows 8 and 8 1 can be very tricky to work with due to the driver signature enforcement The general approach is to disable driver signature enforcement first and then follow the same procedure above to install driver If you are lost Google Windows 8 USBtinyISP or Windows 8 USBasp and you should find some solutions online In the worst case if nothing works try the Rayshobby pre configured VirtualBox image below This will create a virtual Linux in your host Windows system It can pass through USB devices directly to the virtual OS thus avoiding the driver installation issue Compile and Modify the Source Code If you wish to modify the OpenSprinkler sou
