LED Matrix Horizontally
LED s provide a befitting way to electronically display information. whereas the seven-segment LED brandish, organized in the pattern of the digit 8, is common, it does not permit the brandish of some alphanumeric individual features. A 5×7 commanded matrix permits the display of all ASCII individual features, as well as graphics shapes. The circuit in this conceive concept displays an unconventional way to use a 5×7 LED matrix.You can use a conceive encompassing a set of 5×7 commanded flats without altering any thing in the circuitry, except for the arrangement of the commanded units. Using one 5×7 LED matrix, or N units, horizontally instead of vertically allows the display of two characters, or 2×N characters. The minimum pattern for lowercase and uppercase letters requires only a 3×5 LED configuration, except for the letters M and m, which require at least a 5×5 LED configuration and need a dedicated subroutine. The circuit in Figure 1 uses an 8-bit, 18-pin PIC mic...
