9 years ago I've shipped to about 2000 customers and as you said 3 customers have some problem. So the customer satisfaction ratio is 99.85%. That's quite amazing isn't it. Since you are very rude and has made me feel very disturbed and I won't respond to rude customer and that's my principle.
Since you keep closing the posts I'll make one with a lot of details explaining as to what is going on.
More than 3 customers have complained (Both on GIT and Freematics Forums) that their UART adapters stopped working or never worked out of the box. I was the second person to step up (Freematic's forum was the first) and mentioned this issue. I've taken pictures (http://freematics.com/forum/viewtopic.php?f=11&t=1207) and tries this with YOUR CODE and two different Arduinos, 4884 LCDs, two different UART adapters and 4 different cars. One of the wires was brand new. None of which did work, but it did work previously and I do have video proof that it did along with images (http://tinypic.com/r/9iu6wk/8)
The conclusion is:
It can't be anything else. I've shown you my code, my Arduino config, my libraries, my wiring and my Arduinos and proof of everything. It cannot possibly be anything else.
This is no longer about money or getting a project working. I got mine working with I2C. I'd be completely happy if you'd say that UART is broken and no longer supported. However, you're selling these products today and are not supporting your work or the people that have issues with it. It's the principle behind it. If you cannot fix an issue, don't sell anything in the first place to begin with.
Here is a reference to another customer that was very frustrated with your product (http://tinypic.com/r/9iu6wk/8)
In this issue you see him mentioning horrible wiring (Which I've noticed), non-existing technical support and that he is discarding the project and product.
To answer your questions before you ask them: No you do not have to support anyone. It is the principle behind it. You made a product, a thing, stand by your work. All people are asking for is good communication and don't try to avoid their questions and disregard the issues.
Note: When it worked, it was great. I enjoyed it and developed a lot of stuff for it and had a lot of hope for it. All ruined when it stopped working and no support. I'm running I2C now and I'm happy. Issue remains other customers are buying UART and they're out of luck.
It is a waste of my time to make this bug again, it's about the principle of things.
