Re: DM41X Beta Programme

My figures for the DM41X: DM41X Fast mode on battery: 00:07.38 DM41X Fast mode with USB: 00:02.31 DM41X Slow mode: 01:34.19 So my unit seems to be slightly faster than yours. At least on this benchmark. And here is the DM41L, running at 48Hz: 01:16.46. I had expected it to be faster, to be honest.

Re: DM41 RAW file decoder

Thanks ... I just removed the RTN from my code. I cannot test right now if the additional instruction has also disappeared from the online decoded RAW file (not at a computer).

Re: DM41 RAW file decoder

Also, note that, unrelated to the issue you are reporting, you never need to include a RTN instruction just before the END, it's redundant. END acts as both a RTN (popping the stack, etc.) and also as end of program marker. Removing it doesn't save much memory, but if this is used everywhere, it co...

Re: DM41X Beta Programme

What type of category are you suggesting? Are you referring to a Forum category, or something on the 41X itself? I simply am not clear about what you are suggesting, sorry if I'm dense. I am talking about a forum tag (or other convention), e.g. for showing which addtional ROMs must be loaded for a ...

DM41 RAW file decoder

After having saved. and decoded, a RAW file from the DM41X, I notice something strange (RAW file attached): When I use the online decoder (http://dm41.swissmicros.com/) I get the following decoded file (showing the last few lines): X<0? 99999.999 ARCL X AVIEW STOP RTN END LN But when I use the hp41u...

Re: DM41X Beta Programme

Since the DM41X supports loading ROM modules, do we need a new category in the software library, or additional tags?

[DM41X] Hyperfocal Distance and Depth of Field calculator

This was tested on the DM41X, but should also work on the DM41, since no additional ROMs are used This is an adaptation of a Depth of Field calculation that I have stored in my HP 17Bii (I love that solver!). Given the subject distance (in meters), focal length of a lens (in mm), the aperture , and...

Re: Naïve Analysis of TRNG

I'm not expert either but the deficiencies reported are probably due to the cadence of the sample generation. Remember that this function uses the current time as seed, so sample points so near to one another may skew the results negatively. That's what I also noticed when I wrote and tested a rand...

Re: DM41X Beta Programme

Another question is why show the OS in the Manage Modules in Flash screen at all, since you can't actually install it? The answer is because the OS is just another ROM image from the emulation layer's perspective and the Mod and ROMs tools let you inspect details of the OS core modules. But why is ...
