Here is a 5X7 table designed to use with a 5x7 array of leds. It is in the form of a DT table, values are in decimal. Each number is the sum of the hex bits coresponding to the nth vertical stripe in order from left to right, and with the bits from bottom to top, bit 7 not used. This will make it easy to scroll the display. If you ask nicely, i will even design more custom symbols, except for smiley face, if you want that you will have to do it yourself. alice table follows: radix dec ;ascii 7x5 side-feeding characters for led modules ;no you dont need to put them all in dt 0 , 0 , 0 , 0 , 0 ; blank 32 dt 0 , 0 , 61 , 0 , 0 ; ! 33 dt 0 , 48 , 0 , 48 , 0 ; " 34 dt 0 , 60 , 16 , 60 , 0 ; # 35 dt 8 , 18 , 51 , 18 , 4 ; $ 36 dt 25 , 2 , 12 , 16 , 38
