‫Welcome to the BCT display demonstration with the bases to board the bases to board.
‫We have an on board four digit 7th segment display and therefore we do not need the external 7th segment
‫display on the actual breadboard.
‫The only other things we're using for the BCT display are the two slide switches switch zero and switch
‫one switch zero determines whether we're counting in hexadecimal or binary coded decimal and which one
‫enables or disables the counter.
‫Right now we have switch 1 port high.
‫So it's in a reset state.
‫Therefore our counter is staying at a zero in order to start counting or go ahead and switch the switch
‫one down.
‫And as soon as I knew that you know we start to count and we're counting in binary code to decimal or
‫decimal format the format that humans were most familiar with and one two three four five six seven
‫eight nine ten so on and so forth.
‫Now if I take that slide switch zero and pull that high.
‫It'll take this count in the middle of the count convert it to the hexadecimal value and continue counting
‫in hexadecimal.
‫So when I pull that high to see we now are starting to count and the hexadecimal format where we're
‫going through a B C D E F and so on on through and the rate at which we're counting is determined by
‫the P.W. end and put we have regenerating the clock and we're counting off of that which we have currently
‫set to four Hertz.
‫That's.
‫So as this is counting you can see the updates quick enough so you can kind of see as it cycles through.
‫You can if you want to count faster or you just make that rate a higher rate or you want to call slower.
‫You make that a slower rate you make it one her count every second you count up 1.
‫And so I can go ahead and just switch back and forth.
‫So right now the value haven't hexadecimal I can switch it down and there it goes to your decimal value.
‫And if I pull my reset I can reset it when I get poort low again we start back at zero.
‫Now I'm still in the binary code of decimal.
‫I can switch to hexadecimal format and I'll do a reset.
‫Pull it back low and now we're counting in hexadecimal what you notice once you reach the nine you go
‫through the ABC.
‫Yeah.
‫So and so forth and that is the BCT display demonstration running on the bases two board.
