Hello Everyone - I just assembled my IDE board and happily everything passed the assembly steps along the way.
I have output the following and everything passes: QO33,80 ; Configures ports A, B and C as output ports QO32,2B ; Selects right hand pair of digits QO30,01; display 01on right digit pair and work through each bit - all ok QO32,2c; Selects middle pair of digits QO30,01; Should display 01 on middle digit pair, work through each bit - all ok QO32,2d; Selects left hand pair of digits QO31,01; Should display 01 on left digit pair, work through each bit - all ok All displays are correct. Now the final step is the Drive Select and that is where I am having trouble: *Board always comes up with 'Drive B' selected* Now, QO34,0; selects drive A Reset, start again: QO34,1; selects drive A I can never select drive B and on start up, either 0 or 1 to port 34 selects drive A. Any suggestions? There should be no port conflicts in by system...
