Good evening,
My TM1637 doesn't work. I checked the wiring and arduino connections, checked the solder, checked that the screen was active in the game. My module corresponds to the module on the site (not the clock version).
Earlier, 4 months ago, everything worked fine, even work with "The clock Version"! and with the the code like Fanatec (speed+gear).
It always says "no active screens". (i have rebooted simhub many times).
I connect the wires as stated on the site.

P.S. And yet - how to get rid of "COM7 is already use". I want to load other scetch, but i can't.
Thank you!

Hi ! 

I start by the end as I like to get things in reverse 😀 , About the "COM7 is already use". it means another application is already using the serial port, it can be simhub if you don't start the sketch utility directly from simhub, it can be also another app, cura for instance actively polls serial ports like simhub do. I f you are trying to use regular arduino you can configure simhub serial port polling to "leave it alone" using the following instructions : https://github.com/SHWotever/SimHub/wiki/Troubleshoot-other-hardware-Serial-ports-conflicts

Concerning the tm1637 issue as is which is probably an effect of the "no active screen" error, it means that you don't have any screen configured for the current mode (game or idle) :

in order to set a screen either to either game and/or idle, you simply have to double click to edit it and choose the wanted options here :

@admin5435,

Thanks for the quick response! I have moved a little forward, but still something is not clear:
tm1637:
GPU Fan - idle or in game or together - screen worked very well (I think other PC-related features work well too)
GameData.SpeedKmh - idle or in game or both - doesn't work at all
GameData.SpeedLocal - idle or in game or both - doesn't work at all
GameData.MaxSpeedKmh (Computed) - idle or in game or both - doesn't work at all
GameData.Speed - idle or in game or both - doesn't work at all
GameData.Gear - idle or in game or both - doesn't work at all - and showed [NULL] (Others showed 0)
I have no idea why this is happening 🙁

About "Already in use".
I manually changed the port from 7 to 10 and for Arduino IDE it helped, but for the simhab it did not help. I will continue to fight, think, about how to reset the board so that there is nothing there and nothing could use it.

TM1637: I solved the problem, it was necessary to automatically fix the ACC in the "Games" section. After which the game immediately began to betray values to the screen. 👍 

 

"Already in use": I've no idea how to fix it.
