설계 이론 : DashWatch
1. write a detailed system specification.
- times intervals ≤ 99.99 sec.
- acts stopwatch
- permits the best performance (least time) to be stored in a register
- the front of stopwatch : Fig.7-23(a)
INPUT
- START button : causes a timer to reset to 0 and start the timer
- STOP button: stops the timer
the latest dash time : displayed on 4-digit LCD
- CSS (compare and store shortest) button: causes
1) last dash value : be compared with stored as min. dash value,
2) least value to be stored as the minimum dash value, and
minimum dash value to be displayed
- RESET button : initializes the storage register to 10011001.10011001,
max. possible value, and BCD equivalent of 99.99
these reset actions : also occur in response to turning the power on with a switch on back of the DashWatch
OUTPUT
7-Segment : displayed in BCD on a 7-segment LCD
which displays four BCD digits B1, B0, B-1, B-2,
each of which has seven bits a, b, c, d, e, f, g
LED(G8) : provides decimal point (B0.B-1)
acts as a power-on indicator
an input to the display DP which is connected to the power supply.
LED(R1) : TM less than SD
LED(G1~G7) : displayed on G LED which displays seven STEP state
