Driver by Felipe Sanches

There messages are displayed in a 20 digit 14 segment VFD.

|
||||
|
||||
Digits seem to be selected by a mux fed by a counter that is incremented by pulses in P1.2
|
||||
There may be a bit connected to the counter reset signal...
|
||||
|
||||
Segment data is sent to each 14seg digit by first writing half of the data to port P0 and
|
||||
toggling T0 and then the other half of data is written to P0 again but toggling T1 afterwards.
|
||||
|
||||
Changelog:
|
||||
|
||||
2014 JUL 19 [Felipe Sanches]:
|
||||
* Got the display working except for a few glitches
|
||||
|
||||
2014 JUL 16 [Felipe Sanches]:
|
||||
* Initial driver skeleton
