the factory. The termination resistors provide optional bias and termination impedance for the
CAN bus connected to the CAN Port. Type of wire media, data rate, length of wire, and num-
ber of CAN bus nodes all effect the requirement or value of the termination for the CAN bus.
User should refer to particular application for termination requirements.
RC11 CAN-H Bias Resistor: Provides bias to ground potential.
RC12 CAN Termination Resistor: Provides end-point termination between CAN-H and
CAN-L signal.
RC13 CAN-L Bias Resistor: Provides bias to +5V potential.
LCD PORT
The LCD PORT interface is connected to the MCU SPI port and uses a serial shift register to
convert the data to parallel interface for LCD input. This is necessary due to the fast timing
characteristics of the MCU data bus and the slow timing of standard LCD Modules. Example
LCD Port assembly language driver software is provided on the support CD to demonstrate
typical LCD module operation using this technique.
The installed interface, in default configuration, supports all OPTREX ? DMC series and similar
displays with up to 80 characters in 4-bit bus mode and provides the most common pinout for a
dual row rear mounted display connector. The LCD module VEE or contrast potential is set 0
Volts on this board. This configuration requires the LCD module be TN style (Standard Twist)
and Reflective to support this VEE potential. The Axiom Mfg. HC-LCD is also compatible. The
LCD Module is configured for Write only mode. It is not possible to read current cursor posi-
tion or the busy status back from the module.
Connector J2 located directly adjacent to the installed LCD connector support LCD panels up
to 160 characters in 4-bit bus mode. To implement a larger LCD panel, refer to the J2 descrip-
tive text below for configuration information. Refer to the PCB schematic for further details.

RS – Register Select, 0 = LCD Command, 1 = LCD Data
NOTES :
1) The above connector shows connections for a standard 80-character LCD panel.
2) The LCD write requires 3 SPI transfers. Transfer 1 provides data 0 - 3 and RS (register se-
lect) value. Transfer 2 provides the same data with the EN (D7) bit set. Transfer 3 provides
same data with the EN bit clear.
3) Resistor R22 can be removed to apply and external VEE potential.
4) The LCD Port cannot be isolated from the MCU SPI port.
