Hi,
I am Try to create two counters. I think I have got the counter part sorted as they now work as expected where they are broken down into individual digits that fit onto a single display but the part that I am currently struggle is to actually get that data to be display correctly. They are common Anode displays with the segments driven by two unl2003a chips, one for each row/counter. The Anode pins for each row are joined and connected an AVQ252G.
on my latest attempt I seem to have just two 0 displayed on the 1st and 4th digits while the others are not displaying anything at all.
/*
* First draft for configuring 7 segment displays as part of counter project
*
* The Hardware consist of two banks of 5 seven segment displays, each row is controlled seperately by its
* own matrice. The type used for this project are common anode. A prototyping board is used to arrange the
* connections from the Arduino into 3 jst connnects. The anode connections are brought out in the first
* header. The other two provide the individual segment connections for each row respectively.
* connector provides the the annodes for all the displays. The other two provide the individual segment
* connections for each row respectively. currently this just checks for input and increments the counter.
* Once first stage testing has been done a reeal time clock will need to be factored in so that the daily
* count resets. Finally got work as intended however there are issues refreshing the display fast enough
* so may need to rethink and impment a timer instead.
*
* The mapping is as follows
*
* Connector 1 [Common Anodes]:
*
* D16 | PH1 | 6
* D6 | PH3 | 7
* D7 | PH4 | 8
* D8 | PH5 | 9
* D9 | PH6 | 10
*
*
*
* |ROW1_D1|ROW1_D2|ROW1_D3|ROW1_D4|ROW1_D5|
* -----------------------------------------
* |ROW2_D1|ROW2_D2|ROW2_D3|ROW2_D4|ROW2_D5|
*
* Connector 2 [Row 1 segment connections]:
*
* Pin | Port|Segment
* D31 | PC6 | a
* D32 | PC5 | b
* D33 | PC4 | c
* D34 | PC3 | d
* D35 | PC2 | e
* D36 | PC1 | f
* D37 | PC0 | g
*
*
*
* |D31 - PC6|D32 - PC5|D33 - PC4|D34 - PC3|D35 - PC2|D36 -PC1|D37 - PC0|
* ----------------------------------------------------------------------
*
* Connector 3 [Row 2 segment connections]:
*
*Pin | Port|Segment
* D43 | PL6 | a
* D44 | PL5 | b
* D45 | PL4 | c
* D46 | PL3 | d
* D47 | PL2 | e
* D48 | PL1 | f
* D49 | PL0 | g
