PCA8538 Segment Driver evaluation board

The OM13501 is an LCD demo board which can be used to demonstrate and evaluate the PCA8538 segment driver.

This is a chip-on-glass LCD driver which can drive up to 918 segments in mux 1:9. 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 via two AA batteries, an AC adapter or USB.
