Hardware Detail
A.8
Serial EEPROM
A 24LC01 1K (128x8) serial EEPROM is included on the board to illustrate
I
2
C bus concepts. Provisions for an ACCESS.bus
connector (J5) and
associated resistors (R8-R13) are wired in parallel with the serial EEPROM.
For more information on the serial EEPROM, please refer to the most recent
version of the
Technical Library CD-ROM
.
A.9
Keypad Header
J4 is a nine pin header which may be used as a keypad interface. Any 3x4 or
4x4 keypad may be used. For an example keypad, see
LCD Demo
(Chapter 6).
A.10 LCD Header
J3 is a 14 pin header which may be used as an LCD module interface. Many
different LCD modules may be used. For more information on LCD modules,
refer to the manufacturers
’
data sheets. For an example LCD, see
LCD Demo
(Chapter 6).
