“…Partial result is used in the system characters including "0" to "9", "" and "J" a total of 12 characters, display, will send shaped table the first address tab1 DPTR, to display the number into a register, each character dot matrix information difference address numbers into register B (16), through a multiplied by B to display the number of dot matrix information first address, and scan the rows sum as an offset to the address and by MOVC instruction removed corresponding character dot matrix information. Second, establish a buffer D5958 ~D595F, dot matrix information for memory scores in a total of 8 bytes, each buffer content corresponds to a 74ls595, display, through the cycle in turn will buffer content into the accumulator a, a by displacement of the carry bit shift register into the 74ls595 [15]. When a row of data shift after the completion of, set a RCK pulse to realize the data into the data storage register and keep, for strobe signal gating, to achieve the display.…”
