LCD_DEMO.C
troller or an equivalent.
Connect the LCD to the RCM2000 address and data lines on the Prototyping Board.
SWTEST.C
DS2 and DS3 on the Prototyping Board on and off.
Parallel Port A bit 0 = LED DS2
Parallel Port A bit 1 = LED DS3
Parallel Port B bit 2 = switch S2
Parallel Port B bit 3 = switch S3
TOGGLELED.C
the press-and-release method of debouncing. As soon as the sample program starts run-
ning, LED DS3 on the Prototyping Board (which is controlled by PA1) starts flashing
once per second. Press switch S2 on the Prototyping Board (which is connected to PB2)
to toggle LED DS2 on the Prototyping Board (which is controlled by PA0). The push-
button switch is debounced by the software.
