Back in town with some news. I've got a new power supply, and I bought an 8 Letters TID from an Astra F. I switched back to Basic_Functions.ino, which worked pretty good, I can display any text up to eight Letters on this TID. Using the library doesnt work properly. Displaying a short text results in flickering the display, 1 second text, 1 second empty, and so on. I cant judge the scrolling, there is scrolling something, but there is the same flickering. A speed of '4' seems to be the right for me, with 128 the TID isnt quick enough to display letters readable.
Now using my 10 Letters TID: with Basic_Functions.ino, text ist beeing displayed for 4 seconds, 62 seconds blank, 4 seconds text, and after further 75 seconds I gave up waiting. The library isnt working at all.
I didn't mention in the PDF that the arrow J> is the Red/White connector ('gorgeous' put red/grey) that tells the display to display the date or the text string. This wire is just the antenna-power wire given out by the radio that is meant for electric aerials, which tells them to rise or drop when the radio is switched on/off.
My radio always powers this pin, regardless of radio or not, TP or not. In my car, the Pin 5 in the ISO is connected to the antenna amplifier and also to the red/white wire to the TID. Cutting the red/white wire lets the TID always display the date. Cutting the thicker wire on the radio disables the antenna amplifier.
I have made another discovery. Inbetween stop_tid() and start_tid(), a delay of maximum 30ms is allowed, otherwise the display clears the screen. I am using some code like this
char light[12];
for ( int i = 0; i < 70; i++ )
{
start_tid();
tid_address(0x94);
tid_data(0);
tid_data(0);
//tid_data(0); // delete if 8 Letters
//tid_data(light[1]); // delete if 8 Letters
tid_data(light[2]);
tid_data(light[3]);
tid_data(light[4]);
tid_data(light[5]);
tid_data(light[6]);
tid_data(light[7]);
tid_data(light[8]);
tid_data(light[9]);
//tid_data(light[10]); // delete if 8 Letters
stop_tid();
*/delay(30)
a delay of 30ms works at the 8 Letter TID, more than 30ms not.
