Digital tube delay dynamic scanning function
1, program instructions:
This routine demonstrates the connection in the P0 port and P2 port on the eight bit digital tube
Dynamic scanning experiment, through the way of delay.
2, experimental operation
The dial switch SMG S10 end of the ON to the side, indicating that the end is connected.
At the same time, the other end of the dial switch is in a disconnected state, that is, the switch is not transferred to the ON terminal.
Otherwise, it will affect the experimental results.
The program is downloaded to the development board can be observed after the operation of eight digital tube display 12345678 .
