PX-41CX Splashscreens

When turning off the calculator, a temporary screen may be displayed depending on the value of the S.IMG (On/Off) parameter.

You can create your own screen in BMP Monochrome 250x122 format.
Or you can choose from the screens that I had fun composing and download the ones that interest you.

PX-41CX Overlays

Some module programs can be made easier to use using overlays.

You can make your own overlays on Bristol, and cut them with a precision cutter (x-acto knife).

Darren's PX41CX Utility

It is possible to modify a "hex" file (PX41CX firmware) before updating the calculator using a Python procedure available on github.

This tool allows :

to personalize the 4 lines of text on the INFO screen,

modify the list of ROMS loadable in the PX-41CX,

to load the image which will be displayed when the calculator is turned off.
