HSR 8498HB in Serial Mode... help!

[cezik]

Hi!

I try to get to the Serial Mode in HSR 8498HB. Unofortunately I can't... and I don't know why. I send the right package to the serwo, but the servo do not respond.

GCC Code is pretty simple, made on delays:

Code: Select all

// SET MOTOR SPEED AND READ POSITION//

      // HEADER //0x80// 1 1111 1110 00
      PORTC = 0xFF;
      _delay_us(8*52);
      PORTC = 0x00;
      _delay_us(3*52);
       
      // COMMAND // 0xE9 // 1 0110 1000 00
      PORTC = 0xFF;
      _delay_us(1*52);
      PORTC = 0x00;
      _delay_us(1*52);
      PORTC = 0xFF;
      _delay_us(2*52);
      PORTC = 0x00;
      _delay_us(1*52);
      PORTC = 0xFF;
      _delay_us(1*52);
      PORTC = 0x00;
      _delay_us(5*52);

      // DATA 1 = SERVO ID // 1 1111 1111 00

      PORTC = 0xFF;
      _delay_us(9*52);
      PORTC = 0x00;
      _delay_us(2*52);

      // DATA 2 = SPEED // 1 1111 1111 00

      PORTC = 0xFF;
      _delay_us(9*52);
      PORTC = 0x00;
      _delay_us(2*52);

      // CHECKSUM = 1 0110 1001 00

      PORTC = 0xFF;
      _delay_us(1*52);
      PORTC = 0x00;
      _delay_us(1*52);
      PORTC = 0xFF;
      _delay_us(2*52);
      PORTC = 0x00;
      _delay_us(1*52);
      PORTC = 0xFF;
      _delay_us(1*52);
      PORTC = 0x00;
      _delay_us(2*52);
      PORTC = 0xFF;
      _delay_us(1*52);
      PORTC = 0x00;
      _delay_us(2*52);

      // 00 // 1 1111 1111 00

      PORTC = 0xFF;
      _delay_us(9*52);
      PORTC = 0x00;
      DDRC = 0x00;
      _delay_us(2*52);
      DDRC = 0xFF;

      // 00 // 1 1111 1111 00

      PORTC = 0xFF;
      _delay_us(9*52);
      PORTC = 0x00;
      DDRC = 0x00;
      _delay_us(2*52);
      DDRC = 0xFF;


What is that I do wrong? Somebody?

Have you managed to talk to the servos using the serial interface ?
