#13844 - LED display program |
hi,
this is my question. write a program to read 4bit input from port0.0~p0.3 as a hexdecimal number and output ot the LED port P1. P1 drives an 8bit OC invertor (ULN2803A) connected to a common anode LED. For example, P1.0~P1.7 go to L1~L8 => LED segment A~G and Dp. (use the 8051 assembly language) |
