For this what one requires from the

microprocessor.board are, three address lines (A0, Al and A2), eight data lines (DO to D7) and one control line (IOW). The 5volt supply should be capable of providing about 2 to 3 amperes of current for catering to the load requirement of circuit in Fig. 1 and 48x8 LED matrix board shown in Fig.2. If necessary, additional 5volt supply circuit with common ground may be incorporated. Total memory The LED lighting applied to rolling stock adequately based on the operating environ,ment and the characteristic of LEDs is developed. The LED driving circuit, heat sink, and mechanical structure are discussed in the paper, and the simulation to the LED matrix circuit with ANSYS is used to analyze the heat dissipation. The experiment provided

the.evidence that the train onboard LED lamp designed is adequate for electromagnet and vibration environment of a running train. Keywords: An LED matrix is also known as a diode matrix, referring to the LED's onedirectional polarity. An LED matrix is a twodimensional grid with an LED connected to each intersection where a row crosses a column. The columns and rows are isolated from one another in order for the matrix to work. In electronics this is also known as multiplexing. Figure 3.3 illustrates the entire schematic of all the connections. To the right, you will find the matrix layout. All the negative sides of the LEDs are If you set the pins the other way around, however, the LED would not light up. There are two LEDs

for.each of the 64 positions on your matrix. In this project, your code goes through each of the red LEDs at each position to light it or turn it off. When you wire up columns on a twocolor LED matrix, you connect the red LED pins (for example, 23, 20, 17, 14, 2, 5, 8, and 11). In the illustrations, I show how to connect the red ones. If you prefer, you can connect to the green LEDs (for example, //turn off a l l decimal points s segp > setdp (0x00); 14.3 PROJECT IDEAS An LED matria, is a device that arranges a collection of discrete LEDs in a square or rectangular grid. An 8by8 matrix is shown in Figure 14.2. The schematic of the 8by8 matrix is shown in Figure 14.3(a). The LED grid is controlled by eight row signals (rs, rô, . .

.,.rô) and eight column signals (c.7, c6, . . ., c0). A specific LED can be turned on by creating a forward bias between the corresponding row and Schematic diagram of an optical matrixvector multiplier. (Bocker, 1984; Barakat, 1987). One method is to use the matrixvector multiplier shown in Fig. 34. Let A be an N × K matrix, B be a K x M matrix, and C be their To perform this operation using the matrixvector multiplier, we write bi on the LED array and read the vector c1 from the photodiode array, and then we keep feeding one column of B and read one column of C at a time. In M cycles we obtain the result of the operation. C (c) 64 × 64 cells (periodicity: 2.5 mm) (d) Figure 13.5 Floatinggate transistor and organic activematrix
