Re: Internal FAT Lifetime

I suspect you are likely to wear out the STM32 CPU's internal flash with a guaranteed 10000 write cycles before wearing out the external QSPI flash with a guaranteed 100000 write cycles.

Re: Imperial gallons

Might be worth checking where else the world the same gallons are used as in UK - Australia and Canada at least. Although those countries, and the UK, buy petrol in litres. And yet in the UK we use mpg. But some Caribbean countries, apparently, still buy petrol in Imperial gallons. And Ireland sell...

Imperial gallons

How would people feel about a mode setting that switched between U.S. customary units (the default) and (British) imperial units? It would affect the gal->l and l->gal conversions. I suppose it could affect the operation of some programs, but probably for the better for those that need it. It might ...

Re: Where to install DM42 .prg files

I have no idea what .prg files are. There are .pgm files that are the "application" loaded by DMCP "operating system", for example DM42-<version>.pgm is the DM42PGM application that is the port of Free42. DMCP loads the .pgm file into the CPU's internal flash memory (which is exe...

Re: DM42-back cover refuse to come apart for battery replacement

Hi guys, I just notice I didn't reply back with the results after watching suggested video. When you look at the main housing and the thinner back plate, the screw hole alow you to push a thin plastic tool against the thread and at the same time holding or puling back the back plate. In this way I ...

I have to agree that it doesn't have much to do with Pascal, except a few keywords like BEGIN and END, and the ':=' assignment token. It doesn't really matter, though.
And those all came from ALGOL!

Re: C43/C47 Bug Reports

I managed to build the GTK3 simulation to run natively on Linux but I am having trouble getting any of the f/g-shifted functions to work, driving the simulation with the mouse. Every time I click on the shift button to select f or g, and then click on another button to select the shifted function, ...

Re: Order of offscreen images

Not sure but I think it depends on the order they were added to the folder :roll: TL;DR. Basically, the pictures are used in the order they appear in the FAT directory table of the OFFIMG directory. If files are deleted and new files are added, some of the new files may be ordered before some of th...
