I programmed a program to control LED flashing at regular intervals. Run, verify OK. as follows:
#include reg52.h #define uint unsigned int;uint timer_inc;sbit led1=P0^1;void inittimer( ) {TMOD=0x01;T...
I bought the development board one year ago. At that time, I wanted to switch from MCU to ARM. Later, I used FPGA in my work until now. So, after I bought the development board, I tested it and put it...
