Unfortunately, once the program is written in the flash memory it can no longer be read back.

For any program stored in the microSD or external flash in the form of 4XE or 4FN file, it is also difficult for it to be disassembled into anything that is close enough to resemble the source code.

Yes. All core display solutions (4D Systems modules that use 4D Systems processors, such as uLCD, uOLED, pixxiLCD, and gen4-uLCD products) are pre-programmed with SPE (Serial Platform Environment). This allows users to interface their favorite controller boards to the display without the need to program the display manually. In this setup, the display acts as a slave device.

It is also a good idea to consider using ViSi-Genie. This is a codeless Workshop4 environment that allows you to design your user interface that can allow widgets to be linked together. It accepts and processes write commands from the host controller and can also be configured to send reports during certain events.

There is a calibration tool in Workshop4 IDE under the Tools menu.

Start a new project or open an existing project for the display in question, access the Tools menu, and select Touch Calibration.

Follow the on-screen instructions to calibrate your display module.

Yes, you can change the orientation in run time. Here is an example code snippet:

gfx_Set (SCREEN_MODE, LANDSCAPE); // Other Options: PORTRAIT, LANDSCAPE and PORTRAIT_R

See – the ‘Internal Functions Reference Manual’ document for more details, there is a different manual for each of the 4D Processors, so open the one that matches the processor you have.

Yes, with the change in orientation, the display origin as well as the touch screen origin changes accordingly.

Drawing a filled triangle is handled differently in the PmmC since there are no display internal commands that allow fast filling of a triangle.

Each available product includes a download section for all documents related to it. The download section will include product datasheets, software manuals, etc.
