Brymen BM869(867) alternative software.

If you don't wish to share the code, that's fine, but you should know unless your executable have been tested by people and no one reported any issue, no one will trust it. sharing the source code means there is nothing you are hiding and everyone can see what is under the hood!!
I am a professional software engineer and my main field is Microsoft tech.

I have downloaded the file but I will not be able to use it because it is not from well known entity nor being digitally signed and acknowledged by the OS that no one altered the exe by any possible mean

This is how software being treated in the real world!
And BTW you will not go to social media to give a bunch of people interested in electronics and test gear an infected file, you will simply come here  >:D

Nice document by the way.

This is to let a little bit of steam out...  :wtf:

You have the OP, who developed his own alternative software for the Brymen BN869/867. As I understood, one of the reasons to develop this software was to use his own custom made cable (he explains how to assemble one), instead of having to purchase the official cable. Building a custom made cable has the issue, that one lacks the official software - hence why he made his own.

Now pay attention: he offers his software for FREE. A non-intrusive Paypal add is decently asking for any donation.

And what is the general tone in this thread? People say it is not secure to run executables of the internet!!! WTF??? This is a known user of EEVblog! I cannot imagine anyone here using Windows who NEVER downloaded any software and installed it! It's not like he is offering an obscure link to some cracking/keygen site!

And then people say "oh, yeah, all nice, bla bla bla, how about you share the SOURCE CODE, so we can check the software is clean...".

If I was the OP, I would close this thread and not even reply.

It's not just that people want things for free - now they want the source of other people's work, too. Just because.

And what would stop people from doing exactly the very same thing that you are describing, unless this person is a well known entity or his software being tested by others to make sure it is not malicious ???

This is a known procedure that everyone should go through if they would like there software to be spreaded between people, upload it on repeatable repository if he wants the thing to go free.

The policy of free closed source software is not accepted from the majority of the experienced windows users. because anyone that have been using windows long enough would know that free software\closed source is the NO.1 source of viruses.

We are not saying that his software is malicious or contains something, the fact that "it is very easy to infect someone's pc by .exe from someone on the on internet" makes people simply suspect any executable they see floating around.

If I will ever do a software for personal use and would like to share it I will never dare to share the .exe only !! because I know that people will immediately suspect it the moment they see it!

Ok i spend some time and write arduino sketch. It all about IR transistor position and pullup resistors value (in case of my setup is 69K tolerance ~ 1K).If you have bad alignment or wrong value you will receive crap signal and software will not react or start show weird stuff (weird reading mean that you on right way). In ajusting  may be helpful port debug line to view recived data (in GUI port>port debug line).


JackM:
Did you have to shield either the LED or phototransistor from external light at all? Or did that not really affect the readings?

In case of LED good resistance value it enough (to obtain decent brightness) no shielding required.

In case of IR phototransistor all complicated i have cheap one from ebay (no datasheet,no info about type). It has black not transparent body but it react on light (~up to 10-15% of signal) so cover is recomended. To get good signal from DMM you need good alignment of DMM IR LED and your IR transistor.As i said before you need correct pullup resistors value.
