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

HSR 8498HB in Serial Mode... help!

2010-02-17T12:15:48+01:00

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:: // 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?
