(2) Fig. 3 attached (LED three look display circuit schematic diagrams 3)
LED dual-colour digital code pipe shows three kinds of color courses of work:
A, demonstration redness:
(1) send a video data (character code):
Single-chip microcomputer first Enable Pin (pn.x1) output high level opens the output terminal Q of segment encode latch XSU1 to the Enable Pin LE of segment encode latch XSU1.A single-chip microcomputer video data of output (character segment encode high-low level) is to the input end D of segment encode latch XSU1, and data (character) are delivered to the segment encode end of LED dual-colour digital code pipe through segment encode latch XSU1 output terminal Q.Single-chip microcomputer first Enable Pin (pn.x1) output low level again makes segment encode latch XSU1 output terminal Q close that (at this moment the output terminal Q of segment encode latch XSU1 keeps original video data (character code) to the segment encode latch XSU1 section of enabling end LE.
(2) show a red data (character code):
Single-chip microcomputer second Enable Pin (pn.x2) output high level opens the output terminal Q of red bit code latch XSU2 to the Enable Pin LE of red bit code latch XSU2.Single-chip microcomputer output bit code low level is delivered to the input end D of red bit code latch XSU2, deliver to the red position end WR of dual-colour digital code pipe through the output terminal Q of red bit code latch XSU2 after.Single-chip microcomputer second Enable Pin (pn.x2) output low level again closes the output terminal Q of red bit code latch XSU2 (the output terminal Q of at this moment red bit code latch XSU2 keeps original red position low level) to the Enable Pin LE of red bit code latch XSU2.
B, demonstration green:
(1) send a video data (character code):
Red with showing＜as to send a video data〉identical
(2) show a green data (character code):
Single-chip microcomputer the 3rd Enable Pin (pn.x3) output high level opens green bit code latch XSU3 output terminal Q to the Enable Pin LE of green bit code latch XSU3.Single-chip microcomputer output bit code low level is delivered to the input end D of green bit code latch XSU3, after green bit code latch XSU3 output terminal Q delivers to the green end (WG) of dual-colour digital code pipe.Single-chip microcomputer the 3rd Enable Pin (pn.x3) output low level again makes green bit code latch XSU3 output terminal Q close (at this moment green bit code latch XSU2 output terminal Q keeps original green position low level) to the green bit code latch XSU3 section of enabling end LE.
C, demonstration yellow:
(1) send a video data (character code):
Red with showing＜as to send a video data〉identical
(2) show yellow data (character code):
Single-chip microcomputer second Enable Pin (pn.x2) and the 3rd Enable Pin (pn.x3) output high level all leave red bit code latch XSU2 and green bit code latch XSU3 output terminal Q to red bit code latch XSU2 and the green bit code latch XSU3 section of enabling end LE.Single-chip microcomputer output bit code low level is delivered to the input end D of red bit code latch XSU2 and green bit code latch XSU3, after red bit code latch XSU2 and green bit code latch XSU3 output terminal Q deliver to the red position end WR and green position end WG of dual-colour digital code pipe respectively.Single-chip microcomputer second Enable Pin (pn.x2) and the 3rd Enable Pin (pn.x3) are exported low flat to red bit code latch XSU2 and the green bit code latch XSU3 section of enabling end LE again, make red bit code latch XSU2 and green bit code latch XSU3 output terminal Q close (low level that at this moment red bit code latch XSU2 and green bit code latch XSU3 output terminal Q keep original red position and green position).
(4) yellow color shows adjusting:
XSR1--R8 is the adjusting resistance (8) of red position end WR, resistance scope 10--100 Ω, 1/8W.Because red wavelength＞green wavelength 25%, so adjust the voltage that red resistance just changes the red light emitting diodes in the LED dual-colour digital code pipe, the low more red light emitting diodes brightness of red light emitting diodes voltage is just dark more.Adjust red resistance and can regulate yellow chrominance (regulating the conventional resistance of resistance is 1 Europe).
Five, the three kinds of colors in n (multidigit) position show
As long as the three kinds of colors in n (multidigit) position show inferior a display mode circulation n (multidigit) of required Show Color
