How to connect the single-chip power indicator light

For the power indicator light of the single-chip computer, a conventional connection method was to connect the positive pole of the LED light to the 5V power supply, and the negative pole to the 1k current limiting resistance to the single-chip computer's IO-pin. At this time, when the IO-write 0, the light would be on, and when the IO-write 1, the light would be off. However, there was a drawback to this connection. Every time the single-chip computer lit up, the IO-pin had to output a large current of 10 to 20 microamperes, while the maximum output current of the ordinary single-chip computer IO-pin was only 20 microamperes, which would make the single-chip computer "very tired" and affect the stability of its internal work. In some projects, if you really want to drive it with the IO-pin, you can also add a latch or an inverse between the IO-pin and the direct load, so that the IO-pin provides logic, and the latch or inverse provides power. In addition, in the 51 single-chip computer, you can also read the status of the CPU's indicator lights through the SCF51, using the SSLID parameters 16#74 (16#19) to read all the indicator lights or 16#174 (16#119). Ordinary LED indicator lights can be connected to a 220V resistance (43 - 47K, 2W-3W resistance, the current is generally 5ma; the resistance connected to the bright LED indicator light is 110 - 150K, 1/2W, the current is generally 2ma), but the document does not specify the specific connection between this resistance and the single-chip power indicator light.

Which is better, colored spinning or colored weaving?

Colored weaving and dyed weaving each had their own characteristics, and it was difficult to simply determine which was better. From the perspective of color spinning, it was to first dye the fiber into a colored fiber, then fully mix two or more different colored fibers and spin them into a yarn with a unique color mixing effect. Its advantage was that it could achieve a hazy three-dimensional effect and texture that could not be achieved by dyeing the white base. It had no pollution during use and could control the color difference to the greatest extent. In terms of yarn-dyed fabric, yarn-dyed fabric was a fabric woven from dyed yarn (including fabric woven by shuttle looms and knitted fabric). It had a unique style compared to printed fabrics, but it was more expensive. The total loss of dyeing, weaving and finishing was relatively large, and the production of Taiwan was not as high as the production of white cloth, so the cost increased. In terms of the production of the finished product, the color processing of the dyed fabric was relatively easy to operate if there were not many colors. For example, it was feasible for the machine to pass through the shaft to arrange the color. If there were too many colors, it was necessary to manually pass through the shaft to arrange the color. In contrast, the production process of one-color fabric was easy, and it could be dyed in batches, but it was easy to have problems such as left, middle, right, or head and tail color difference, striations, and shadows. The novel "Dream of Silk Fate" is equally exciting. Everyone is welcome to click and read it!
