General Operation:
The TVM2464BTC can reside on your microprocessor's buss like a memory device or can be interfaced via an unused port including any bi-directional printer port on a PC card. The two address lines are used to direct the module to accept an instruction, unlimited string data or to report back information that is stored in the on-board status register. The instruction set includes commands to activate touch screen areas while drawing buttons on the LCD. A pre-loaded label is also automatically centered within the button area. During button definition a key code is assigned which can be read after the keypress status flag indicates that a valid button closure has occurred. Other commands can control font selection, draw boxes and vectors, turn the backlight on and off, and control the button characteristics and built in audio beeper. The TVM2464BTC uses a 16 bit 20 MHz on-board uP to add a new level of intelligence to the LCD which allows equipment using the low performance CPU cards to obtain a sophisticated and flexible user interface.
An unlimited number of screen fonts can be displayed simultaneously being selected from 2 built in fonts or from 3 down loaded soft fonts. Fonts can be down loaded 'on the fly' as required. A font compiler is included in the designer kit software.
The TVM2464K designer kit includes a module, PC interface card, manuals, software libraries and examples including C and basic source code. This kit can get the module up and running in a matter of minutes and will allow you to test routines before writing and compiling your code.
