The OM13503 is an LCD demo board which can be used to demonstrate
Abstract
and evaluate the PCA8539 dot-matrix driver. This is a Chip-On-Glass
LCD driver which can drive a dot matrix up to 100 × 18 dots with a display
size of up to 7".
The board is controlled by an LPCXpresso micro controller board, which
contains the LPC1115, a Cortex M0 controller. A free IDE can be
downloaded in order to modify the software.
Supply of the board can be done via an AC adapter or USB connector.
