Spending $79 to make an LED light up seems a bit luxurious. You would definitely prefer to use BASIC Stamp to create something more practical. For over 100 dollars, you can make an exquisite digital clock! This may seem too luxurious, but in the future when making various other devices, you will find that these components can be reused.
We will use the input and output pins of BASIC Stamp to display numbers. In the digital clock section, we learned how to connect the 7-segment display LED of the 7447 chip. The 7447 chip can work in conjunction with BASIC Stamp. By directly connecting the four input and output pins of BASIC Stamp to 7447, it is easy to display numbers from 0 to 9. The BS-1 version of Stamp has 8 input/output pins, which can directly drive two 7447 chips.
For a clock, at least 4 digits need to be displayed. In order to drive 4 pieces of 7447 with 8 input/output pins, we need to be more creative. The following figure provides a solution:
In the above figure, 8 input and output pins are introduced from the left. This method uses four input and output pins to drive all four 7447s. The remaining 4 pins are used to activate 4 pieces of 7447 in sequence (the “E” on the chip represents “Enable Enable” – pin 5 on the 7447 chip). To make this system work, the Stamp program first sends out the first number through four data lines and sets the E pin of the first 7447 to the first control line, thereby activating 7447. Then issue the second number to activate the second piece 7447, and repeat the activation of the four pieces 7447 in sequence. In fact, with a slight modification of the wiring, a single 7447 can achieve these functions. By using the 74154 multiplexer chip and some drivers, up to 16 digits can be driven using this method.
This is the standard method for controlling LED display screens in practice. If you have an old-fashioned LED display calculator, observe the display screen while shaking it. You will find that only one number is lit up at the same time. This technology is called multiplex display.
responsible for processing signals from on-site sensors or driving actuator actions. For example, they may need to cooperate with devices such
as BANNER travel switch T30UIPB to receive their transmitted position signals; Or by controlling components such as Burkert solenoid valve 00131421, the on/off of fluid media can be precisely managed.
these modules integrate more complex logic processing capabilities. The core task of a pressure switch is to detect whether the pressure
has reached a preset threshold and output a switch signal. Its function is highly specific and fixed. And modules 5X00500G01 and 1
C31219G01 have the ability to comprehensively judge multiple such switch signals and transmitter signals (such as transmitter 1066-P-HT-60),
and output complex control instructions according to internal logic.
