Backlight OFF when Shutting Down

[almamater]

Hello...

I have one 16x2 LCD and the backlight keeps on, beacuse of the PC standby power supply, even though when i turn off the computer..

Its possible send the command "Backlight(0)" when LcdSmartie closes? Like the Shut Down Message..

Thanks

Smartie sends the backlight off command on shutdown.
Are you able to change backlight on your display? What model is it?

It depends on the display back-panel you have to use a Microprossesor based backpane to achieve this... (eg Matrix Orbital supports such function). I'm afraid this is not possble on Parallel connections and FTDI based LCD's

I thought Smartie could control the backlight on a parallel port connection, with the addition of a transistor and appropriate resistors? The schematics on the Smartie site include the backlight control transistor for parallel port connection.

Not sure if the FTDI/FT245 circuits and driver support backlight control... no mention of it, but there appears to be a spare IO on the FT245 module.

Yes you're right!
but not with standard connection... as you metioned an additiona transistor must be fitted in parallel connection. On FTDI I can be sure that the driver supports such function Needs testing!
