The HCMS-29xx/HCMS-39xx alphanumeric displays have a single data line that accepts data inputs serially. Each character is formed out of a 5 x 7 pixel array by shifting bits into each pixel position (1 = on, 0 = off). The eighth row does not consist of LEDs, but is a pixel position and must be considered a data position when encoding a character to be displayed. Thus, each character’s information content can be stored and accessed as five bytes (40 bits) of information, with each byte representing a column of data. To properly implement the character coding given here, input the most significant bit first (i.e. least significant bit last). The most significant bit of each byte is a “don’t care” since there are no LEDs in the eighth row. The symbol codes in Table 1 represent the ASCII characters shown there and in Table 3. The symbol codes in Table 2 represent the characters shown in Table 4, the Katakana character set. The column and row values for each symbol are shown in the appropriate character set (columns D4 - D7, rows D0 - D3). Ignore the user defined section of each character set (relates to Avago Technologies smart displays that have an internal ASCII decoder). Columns 0, 1, 6, and 7 of the Katakana character set are encoded in the ASCII character set.
