Re: Relative humiditu and dew point

My first post here and. Based very loosely on Eddie Shores Dew point program in his blog http://edspi31415.blogspot.no/2016/07/hp-42s-programming-part-ii-dew-point.html I made a bit more elaborate program. This one takes three arguments "Wet Bulb", "Dry Bulb" (thermometer) and the barometric pressu...

It turns out that MENU only activates the programmable menu; it does not clear flag 48 (ALPHA mode). Making it clear flag 48 fixes this bug.

The fix will be in the next release.
Good! It gets boring when all known bugs are fixed. ;)

SIN 45°

It's nice to see the sine of 45° is properly calculated in 3.1. Thanks, Thomas!

Re: DM42 Firmware V3.1 available

No. The tool doesn't do that. The instructions say, "The help file itself is not part of the firmware so that it can be updated without users having to flash a new complete firmware. " sorry but I read that as providing the capability to update the help file without the need to flash the firmware. ...

Production Beeper Louder?

Has the beeper in the production units been modified to be louder (but not objectionably so) than the beeper in the beta units? Mine is. I like the louder production beeper better.

Re: DM42 Firmware V3.1 available

the update appeared to work fine for me on my beta unit but it did not create or populate the HELP folder. I am copying the HELP in manually, but was the dm_tool flash supposed to do that? Thanks No. The tool doesn't do that. The instructions say, "The help file itself is not part of the firmware s...

Re: DM42 Firmware V3.1 available

Sorry, my bad. I'll correct the link in the original post. It works with your revised link. Thanks again! I answered my own question about 3.1 on beta units. It seems to work fine. I did have to recreate the bootloader INI file so the DM Tool could see the new unit and then recreate it again for th...

Re: DM42 Firmware V3.1 available

I can't find the manual to download. The link doesn't work in either Edge or Internet Explorer. http://www.swissmicros.com/help/latest Also, I don't see anywhere whether or not 3.1 is safe to flash to a Beta unit. Is it? Thanks!
