2. Advanced Hardware Options

The display module (uLCD-32-PTU) is a very capable and powerful piece of hardware, which can be

reconfigured beyond the boundaries of the Serial Environment, which is what is loaded on the module when

shipped.

With the use of the 4D Systems Workshop4 IDE Software, the display module can be configured and

programmed, which enables the user to utilise the display module in more ways than what is possible when

using it in the Serial configuration.

If a user wishes to investigate the capabilities of the uLCD-32-PTU and reconfigure the display module, please

refer to the Datasheet for the uLCD-32-PTU, available from the 4D systems website, www.4dsystems.com.au.

The user can freely change back to the configuration the module was shipped in if desired, all via the

Workshop4 IDE Software.

To take advantage of the 4D Systems Workshop 4 Software, a 4D Programming Cable is required, which can be

purchased from the 4D Systems website, or from a 4D Systems distributor. Depending on what the user

requires, a micro-SD card may also be required. Please refer to the datasheet for the uLCD-32-PTU for more

information, along with information on the Starter Kits which is also available, which includes both the

Programming Cable and a micro-SD card.

If the uLCD-32-PTU display module is programmed to be used with the ViSi-Genie environment, 4D Systems

has created a library for the Raspberry Pi specific for the ViSi-Genie environment. Please refer to the uLCD-32-

PTU-PI product page on the website for more information, along with the link for the 4D Systems Github

repository where this library is located for download.

If the uLCD-32-PTU display module is programmed to be used with the Serial environment, 4D Systems have

created a C library which is included with Workshop 4, but also available to be downloaded from the 4D

Systems Github repository. This library is a generic C library, so not specific to the Raspberry Pi, however can

easily be ported as all source code is included in the repository. An alternative is to not use the library at all,

and utilise the raw commands which can be sent from any host controller. Please refer to the Workshop 4

product page, and download the Serial command set document for more information.
