The LCD-Demo-LPC2158 is a reference design for a low cost microcontroller and LCD solution
using the NXP LPC2158 along with a few discrete external components. The Board is controlled
by a simple two-button user interface (MODE and SELECT). Example source code may be
downloaded for several sample applications: an FM Radio display during a simulated channel
scan, a 15 minute countdown timer, a repeating pattern of 4 text lines, and virtual COM port
allowing users to display their own messages on the LCD. The user can edit this code and
download to the reprogrammable Flash microcontroller directly through a USB virtual COM port
on the user’s PC (no external programmer required). The LCD-Demo-LPC2158 can function as a
Single Board Computer since the powerful LPC2158 contains an ARM7TDMI-S microcontroller
with 512 kB of programmable Flash memory and 40 kB of RAM. Additionally, the 20-pin
expansion header allows for the connection of external devices to the microcontroller directly
through GPIO or through the SPI and I
2
C interfaces.
