Simulation experiments of 8086 and 8255 based on Proteus
(1) basic input and output experiments. Write a program, so that 8255 A port for the input, B port for the output, to complete the dial switch to the data lamp data transmission. As long as the switch is toggle, the display of the data lamp will change accordingly.
(2) water lamp display experiment. Programming, 8255 A and B ports are output, data lights D7-D0 from left to right, each time only one light, circular display, D15-D8 and D7-D0 are opposite, from right to left, each time only one light, circular display.
