i'm afraid a picture wouldn't be of much help, but here is how i connected the tid to my mega
tid connector pin
1 -> +12 V
2 -> disconnected
3 -> ground
4 -> disconnected
5 -> disconnected (i tried this to +12 but the tid goes off... even if it shouldn't)
6 -> disconnected
7 -> disconnected
8 -> +12 V
9 -> pin 5 on my mega
10 -> pin 6 on my mega
11 -> pin 7 on my mega
12 -> disconnected
worth to mention that connections for 9,10,11 needs to be configured when including the library into your project (see tid.h)
Strange dunno why it's doing that.
And the mega works fine with the coms lines!
Ok something I came across on a car forum is that, some hoe the display is able to retrieve error codes from the edu.
Is it possible to get the arduino to both read and write on the i2c bus?
while inside my car, i could press both buttons of my display and after a while it would show me the speed and then show a "test screen" with all characters lit. Once removed from the car, connected as i told in the post above and powered up, doing the same operation made all stored fault codes appear in sequence. I'm not sure why this doesn't happen when mounted inside the veichle, nor if those codes can be retrieved from the tid, all i know is that read operations on i2c bus need a 1 after the address, so in this case the address byte becomes 0x95
taking for granted that you have already checked your connections throughly, first thing you should try is changing the string from "hello" to "HELLO" since the display can't display lowercase characters XD. Another curios thing about this display is that every minute the screen is cleared of all symbols and characters (this is done by the display itself, not by my library, and i don't know if it's possible to avoid this), so since your sketch includes a 2s delay, the only symbol shown goes away for up to 2 seconds from time to time. BTW, all other symbols are working too? if you assign i=1 you see the dolby c and so on?
Whats the IC numbers in you clock as I can't find any info of the chip in mine?
the main ic is a ST6 microcontroller, from what i gathered here it's a ST6240B that is factory-programmed, so the number on the chip (ST624306/A2) shows nothing when searching for datasheet.
Do you have a blog?
Have you tryed hackaday?
I would dry AOC (Astra Owners Club but don't know my password.
