Trouble Shooting
This section describes typical problems and how to fix them.
EyeBot does not boot at power on or reset.
- Does the display show a horizontal line when pressing reset?
If so, you probably accidentally erased the RoBIOS
operating system from the flash-ROM.
Look at section Debug
on how to reinstall RoBIOS using the background debugger.
- Does the display not show anything at all?
In that case, you may have blown the controller's fuse,
either by connecting power with wrong polarity or by
a too high current (e.g. short circuit).
Use a multimeter to check whether any current is flowing
when you switch on the EyeBot.
If current is flowing, try to re-install RoBIOS via the background
debugger as discussed above.
If no current is flowing, see the
instructions to replace the fuse.
EyeBot serial connection to PC does not work.
- Make sure serial cable is connected correctly on EyeBot
and serial port COM1 on the PC (or any other port if you change
the standard scripts).
- Make sure the Baud rate on the EyeBot and on the PC match
(EyeBot standard is 57,600 Baud - some older PC cannot go
that fast).
See section Download on how to
change serial settings on the EyeBot.
EyeBot BDM-connection to PC does not work.
- Make sure BDM cable is inserted correctly on EyeBot (pin 1 is marked)
and on PC (in parallel port).
- Make sure PC's parallel port is set to "EPP" mode.
You can change/verify the port setting by entering the system setup
when booting the PC (usually by pressing the "Del" key during bootup).
EyeBot wireless communication demo does not work.
- Make sure the optional wireless communication module is inserted.
- Press menu item "< I >" from the main menu on the EyeBot,
then press "REG".
This will display the "Register Radio" screen. You need to
send (email) the serial number displayed on the LCD to your
distributor, who will supply you with the security key to enter.
After this procedure, the wireless communication functions
are enabled.
EyeBot LCD has poor visibility.
- There is a potentiometer on the underside of the LCD
with which you can change the contrast of the display,
