I suspect the TM1638 board I have "QYF-TM1638" one with no discrete LED's is not right, Setting registers sequentially it displays digits from right to left, 1 digit data goes to all digits same segment. https://youtu.be/FOhTs2_JT_A
If someone has a different 8 digit TM1638 board & can test it would be most helpful. It will be some weeks before I get new different boards.
The attached .gcb is setting registers of the TM1638 0 to 16
The display should show :
"2" at digit 2 for 1 s,
then all segments on for each digit in turn left to right,
then each segment- each digit left to right.
You should also see the discrete LED's come on.
I am fairly confident the code is good as the 3 wire SPI message looks ok.
Display on/off & brightness work as expected.
Just set #chip & ports to your device. Test_TM1638 Registers.gcb
The display should show :
"2" at digit 2 for 1 s, I got the letter F
then all segments on for each digit in turn left to right, - Yes
then each segment- each digit left to right. - Yes
You should also see the discrete LED's come on.-Yes
Thanks Evan, much appreciated.
The boards I ordered look like that one. I can investigate why the 2 is an F, should be easy enough to find
Now I know I am on the right train.
cheers

113d that I send is an F so that's working ok. I just misread a table, 2 is 91d
OK! A video is the best way to show these things.
The questions is... where is the train going? Can I come with you?
I wouldn't trust any Trains in England at the moment :>)
I'm on the train to everywhere with an undefined timetable.
bit like a subatomic particle
Then be carful not to meet the The Large Hadron Collider that really would be the preverbal Train Smash. :)
I am on the last train to Clarksville. I could meet you are the station, you can be there by 430 ?, I could I've made your reservation ..... :-)
Another Monkees Fan :-)
Aye. The Monkeys went to Clarksville and Glenn Miller went to Chattanooga. Where must they have got on the train ? ( you may need a map of Tennessee )

Without consulting a map I would Imagine Nashville as it is a not only a major rail hub but also the holy grail of American Musicians.
Winner. Nashville - they would have had to go via Nashville.
Glenn Miller journey ( in the song ) started in Pennsylvania but Nashville was on route. :-)
Johnny Cash when to Folsum ( at least in a song)
