‫Welcome to the RTC 7 BCT display demonstration.
‫I currently have the BCT display running on the RTC 7 where I have a four digit seven segment display
‫located on the breadboard where I have each of the seven segments are connected through a 56 ohm resistor
‫into the J.
‫P. mount port of the RTC 7 and I have each of the digit selects running through a 2 and 39 no for unpin
‫transistor where I have a 470 ohm resistor connected to the base of these transistors and then fed back
‫into the J.B. port payment of the RTC 7.
‫Now if I have and I haven't reset currently So here's a port on reset my sarcy account show up on the
‫7 segment display and this is counting in binary code decimal.
‫So it's a way we can understand you know four five six seven eight nine.
‫So and so forth.
‫If I switch and now I'll be counting and hex you'll notice we go up through five six seven eight nine
‫ABC F F G.
‫Now if I go ahead and toggle this out it switches back over to decimal.
‫So the decimal value and as soon as I toggle I go directly to hex and I can also switch and this will
‫put me back to zero and if I plot 0 I'll start recounting from 1 on up.
‫Now if I'm in hex You'll notice I go from 1 on up to F..
‫And so on and so forth.
‫And so as I go through I can just set this switch here and toggle back and forth while I want to go
‫in hexadecimal or if I want to go an actual binary code of decimal as well.
‫You'll notice that the count is counting at 4 digits per second.
‫That's because the Peter Block We have specified to run at 4 Hertz meanings that will have it will count.
‫Increase the count four times every second.
‫So by changing that value we can have it go slower.
‫So it's easier to see or you can have it run faster.
‫I want it to go fast enough so you can see it change to the various digits.
‫But I also want it to be slow enough so that you can see what's actually happening.
‫And so this is what the BCT display should look like running on your RTC 7.
