I really don’t down where the problem is,When i connect the sprinkler to computer with USB,my computer has no response,LCD of sprinkler shows “Detecting uSD…” and soon will turn to “Connecting…”,after a minute “-Disabled!-“,This problem makes me can’t do any change, I had install the usbasp-windriver,According to the Recommand,hold B2 2s and choose the usbasp.2011-05-28 folder,But when i pull up the USB and connect again,Everything goes again,just as i said before,Please help me solve this problem,thank you very much!
1) To enter bootloading mode you need to unplug power, and press and hold pushbutton B2 while plugging in a USB cable. Then release B2 within 1-2 seconds after the USB is plugged in. This way the controller will appear as a USBasp device. The screen should remain off. If the screen lights up, the controller will not appear as a USB device, and you need to repeat the procedure above.
2) The ‘Disabled’ message means the controller operated has been disabled. You can re-enable it either by pressing and holding pushbutton B1 for 2-3 seconds (until the ‘Disabled’ message goes away), or you can enable the operation through the web interface. These have all been explained in the user manual, available at http://www.opensprinkler.com -> user manual.
