Re: Hello World

The main issue with the CR2032 as far as I understand it is that it’s internal resistance increases significantly as it’s coming close to depletion which causes significant voltage drops upon short peaks of current as the ones generated by the operations of our calculators. These voltages drops are ...

Is it caused by the single CR2032? Is this design too ambitious? But there are also some HP-12C powered by such a cell IIRC. What else? :?
See this old thread: HP20B low battery warning doesn't work, and specifically post #12 about CR2032 internal resistance.

Re: Hello World

The worst that happened was that the flash drive once became corrupted when one of my programs wrote to it with low battery. I had a backup, and after formatting the drive and copying things back everything was all right once more. It's a good practice to call the DMCP function power_check_screen()...

Re: Hello World

I would recommend to read the DMCP Development Manual where you’ll find such “Hello World” demos.

Re: C47 Printing to I/R?

I/R printing is currently not implemented neither on the C47 nor the WP43. The print functions available on the C47 send their output to a file on the FAT.

Re: Assign the f shift or g shift function to a MyMenu location?

There is a very simple solution to the location of the f and g functions, and it’s already implemented in the C47: removing f and g shifted functions ! You just have to enable the HP-35 mode and then enjoy a calculator with a clean layout where each math function is directly accessible without any o...

Re: C47 Bug Reports

Very cool. 8-) This is a feature I will be using. I understand this is still a work in progress. I noticed that if I assign (for example) the RECT \odot or POLAR \odot function to a user defined menu (not to be confused with MyMenu), it is displayed without the indicating \odot . The function works...

Re: C47 Bug Reports

I am creating two menus (I think this is allowed, but maybe that is my incorrect assumption...?) […] Now I want to assign these menus to (what is the right term) "my user menu" I guess. […] Now when I use "my user menu", and select MEN1 or MEN2, they both open the same menu... (...

Re: Help Understand Coconut VASM Listing

BTW, May I know where can I find the full 12 files listing ? If you have the GFF VASM listing it already includes the 12 files (CN0B...CN11B). A long time ago I converted the HP VASM listing into sources files for Warren's SDK41 that can be assembled, linked and converted into ROMs fully identical ...
