FLASHLEDS.C
tions, and costatements to flash LEDs DS2 and DS3 on the Prototyping Board on and
off. LEDs DS2 and DS3 are controlled by Parallel Port A bit 0 (PA0) and Parallel Port
A bit 1 (PA1).Once you have compile this program and it is running, LEDs DS2 and
DS3 will flash on/off at different rates.
FLASHLEDS2.C
DS2 and DS3 on the Prototyping Board on and off. LEDs DS2 and DS3 are controlled
by Parallel Port A bit 0 (PA0) and Parallel Port A bit 1 (PA1).Once you have compile
this program and it is running, LEDs DS2 and DS3 will flash on/off at different rates.
KEYLCD.C
Connect the keypad to Parallel Ports B, C, and D.
Connect the LCD to Parallel Port A.
Once the connections have been made and the sample program is running, the LCD
will display two rows of 6 dots, each dot representing the corresponding key. When a
key is pressed, the corresponding dot will become an asterisk.
