5. PmmC/Firmware Programming
The PICASO processor used in the µLCD-43 module
is a custom graphics processor. All functionality
including the high level commands are built into the
chip. This chip level configuration is available as a
Firmware/PmmC (Personality-module-micro-Code)
file.
A PmmC file contains all of the low level micro-code
information (analogy of that of a soft silicon) which
define the characteristics and functionality of the
device. The ability of programming the device with
a PmmC file provides an extremely flexible method
of customising as well as upgrading it with future
enhancements.
A PmmC file can only be programmed into the
device via its COM0 serial port. Figure below
provides a typical implementation for the PmmC
programming interface.
The PmmC file is programmed into the device with
the aid of Workshop 4, the 4D Systems IDE software
(See Section 11). To provide a link between the PC
and the ICSP interface, a specific 4D Programming
Cable is required and is available from 4D Systems.
Using a non-4D programming interface could
damage your display, and void your Warranty.
