The VGA is an analog video signal and DVI is a digital video interface. The DVI provides a higher quality of the picture comparing to VGA. Since your monitor supports both interfaces, I'd go with a DVI.

Please verify that your touch screen is properly connected to the J8 connector on the TC553/852 controller. Carefully pull the latch on connector J8 out. Insert the flex cable into J8 being sure it's seated, push the latch back in. Also, please make sure that the flex cable is not bent or damaged in...

I'm glad it worked for you. Sorry, I can't recall the link right now. Just do a search on AVR Freaks forum, and you'll find it for sure.

Good Luck!

This was already answered once on AVR forum. The space character is the separator. I wouldn't use scanf. Collect characters in a buffer until a space is received, then process the string. Replace the comma with a null character, remember where the comma is and you have two separate strings that can ...

The way I see your project is by using TVI Electronics' TouchScreen LCD Module connected to your Atmega16 or 32 microcontroller through the serial port. For a connection diagram please refer to TCxx controller User Manual . The connection for the serial communication is the following: TxD from TCxx ...

TVI Electronics now offers a touch screen add-on for Optrex F-51320, F-51553, F-51852 and F-55472 LCDs.

2.8" 4-Wire Resistive Touch Screen [TSR-51852]

The link is fixed now. Thanks for pointing this out.

Could you please tell me why my brand new F-51553 LCD doesn´t work with TC553/852 controller? I can only turn ON/OFF the LCD backlight and contrast with the Control Panel but I can not display anything on the LCD. The TC51320 and TC553/852 controllers have a trimmer potentiometer for contrast adjus...

The TouchKit software supports different types of communication, including RS232, PS/2, USB, and I2C. However, TVI Electronics does not have touchscreen controllers with I2C interface. Right now we offer 4-wire resistive controllers that support either USB or RS232 communications.

Hi rtaubitz, The TC51854 firmware and DCA software are now available to support AT45DB081D flash memory. To download, click the links below. Use your custom access user name and password to download the files. DCA with 8Mb support TC51854 firmware with AT45DB081D support There are two new commands a...

Check your PM for username and password for TC51854 controller firmware download.

It'll take some time to modify the firmware and the DCA software to support the AT45DB081. I'll let you know when it's ready.

When the touch screen calibration was completed, regardless the outcome (succeeded or not) "Done" or "Please repeat calibration" message will appear and the controller will send the "!" (exclamation mark). You can verify your controller's responses by using a Windows HyperTerminal. To start the touc...

rtaubitz, thanks for keeping up with the forum. Mahlhavoc, as rtaubitz already said, it'll be much easier to start your project from the scratch rather than attempting to communicate with the existing controller without knowing how to parse the data. Either way you choose, it'll require a knowledge ...
