More Pinouts would be nice indeed. Wondering when we get more. Seems that thete is no work for me anymore, so just waiting?

A request was made to make translations possible (https://openrepos.net/comment/23826#comment-23826) and, on request, I briefly explained how to add more pin layouts (https://openrepos.net/comment/23826#comment-23826). The description asks for personal contributions to more pin layouts. But I never got a response. Apparently people have their priorities elsewhere when push comes to shove. No problem, but don't expect me to chip in as usual, I think I did my share on expanding this app.

Very useful. Is there a way to make the selection in color choosers better readable (for example a small arrow next to the chosen option)?

Not sure if arrows is what I would like. But I made some changes in the latest release that highlight the selected color more clear.

It should not be that hard:

  • Get your clipart in a width of about 700pixels (it get's resized, so not very important)
  • Then you can take serial_pins.qml (see github) as a start for a new connector. Change the listelements (text and amount of elements) and refer to the new clipart (png)
  • The new page should also be added to the MainPage.qml, also via a new listelement

Your "Sources on github" is kind of fu**ed up. ;)

Anyway, thanks for the app. Will become handy.

Hi. Thanks for this app. Can You create support to translater your app? Thank

Hi,

I made the strings translatable. You can find the base file in the translations folder in the github repository now (harbour-ohm.ts). Qt 5 Linguist kan be used to create a translation.

Thanks a lot. Very useful app. I remember ElectroDroid on my Android phone ages ago ;-)

It would be great, if you could add a DMX512 calculator for dip switches similar to this on google play.

I think I can add this calculator. But as I wrote in the description: please create your own additions if you want them. I am not willing to spend more of my free time adding things I am not familiar with and won't use at all.

Oh, how fast, thank you so much. I am very happy. Can I make a donation in any way for your work?
