Hi,
I would like to seek clarifications on the Din and Dout modules with respect to their relationship regarding button numbering and the correspondent LED numbering. There are 4 shift registers, IC1 to IC4 in each Din and Dout module. I take it that IC1 to IC4 represents shift register 1 to 4. The schematics show the following mapping for the buttons and correspondent LEDs.
IC1 - 74HC156 IC1 - 74HC595
pin# button# pin# LED#
11 1 (D0) 15 1 (D0)
12 2 (D1) 1 2 (D1)
13 3 (D2) 2 3 (D2)
14 4 (D3) 3 4 (D3)
3 5 (D4) 4 5 (D4)
4 6 (D5) 5 6 (D5)
5 7 (D6) 6 7 (D6)
6 8 (D7) 7 8 (D7)
Have I intrepreting this correctly? The mapping as given in the main.asm file is as shown in the snapshot. I need direction in this respect. Thanks
Best regards
Shum
