LCD Module
SAM3S-EK connects the USART1 bus (including TXD, RXD, RTS, CTS handshake signal controls and
EN command) to the DB9 male connector J5 through the RS232 Transceiver MN5.
Figure 4-6.
As noticed above, the USART1 is shared with the RS485 port, connected to the transceiver MN4, con-
nected to the 3-point connector J4. The design includes selectable jumpers for RS485 bus termination
resistors selection (JP10, JP11, JP12).
Figure 4-7.
The SAM3S-EK carries a TFT Transmissive LCD module with touch panel, FTM280C34D. Its integrated
driver IC is ILI9325. The LCD display area is 2.8 inches diagonally measured, with a native resolution of
240 x 320 dots.
The LCD module gets reset from the NRST signal. As explained, this NRST is shared with the JTAG port
and the push-button BP1. The LCD chip select signal is connected to NCS1; the jumper JP13 can dis-
connect it so that this PIO line is available for other custom usage.
The SAM3S communicates with the LCD through PIOC where an 8-bit parallel “8080-like” protocol data
bus has to be implemented by software.
