/////////////////////////////////////////////////////////////////////////
//// EX_LCDKB.C ////
//// ////
//// This program uses both the KBD.C and LCD.C drivers to allow ////
//// keypad entry and LCD display. All keys are echoed except * ////
//// that will clear the display. Either the kbd_getc or lcd_putc ////
//// may be replaced with getc or putc to use just one device with ////
//// the RS-232. ////
//// ////
//// Configure the CCS prototype card as follows: ////
//// Plug in both the LCD and KEYPAD. ////
//// ////
//// This example will work with the PCB, PCM and PCH compilers. ////
//// The following conditional compilation lines are used to ////
//// include a valid device for each compiler. Change the device, ////
//// clock and RS232 pins for your hardware if needed. ////
