Drive the port set to sbit pul_0=P2 ^ 0;//level motor pulse input
Sbit dir_0=P2 ^ 1;//level of motor control end
Sbit ena_0=P2 ^ 2;//motor so that can end
Communication protocol is a moving target barycentric coordinates (X, Y) will continuously through the serial port output, program output 5 bytes, as shown in the following table, the opening of the first byte 0 x80, second, three bytes of barycentric coordinates X and Y respectively (in pixels), the fourth byte marked, 0 (the two cameras captured targets at the same time, 2 for moving targets beyond the view area, at the end of bytes for the final value of 0 xee, start bit and end value set to better ensure the effective transmission of data,
Data output description
0 x80 X Y FLAG 0 xee
Want to ask you, the c + + program how to write?
CodePudding user response:
Ask factory to sample code, faster,CodePudding user response:
No one,,,,,,,,CodePudding user response:
Buy another example code, faster.CodePudding user response:
There is a problem with this agreement, if the X and Y in 0 x80 and 0 xee?
