Compared to the Pololu Baby Orangutan B User’s Guide, pololu.com/docs/0J14, page 12, I realized the commands for driving the motor (look to drive side) clockwise or ccw (math-pos) and stopping different. Motor: 298:1 Micro Metal Gearmotor with Extended Motor Shaft, #2208.
MY Code:
// ============================================================================= =
void M12_for ( u8 pwm ) // Motor 12 forward
{ OCR0A = pwm; OCR0B = 0; } //
// ============================================================================= =
void M12_rev ( u8 pwm ) // Mot 12 backward
{ OCR0A = 0; OCR0B = pwm; } //
// ============================================================================= =
void M12_stp ( void ) // Beide Kanäle low ==> Aktiv bremsen
{ OCR0B = 0; OCR0A = 0; } // channels low, break
// ============================================================================= =
void M12_brms ( void ) // Beide Kanäle high <=> Ausrollen, stop
{ OCR0B = 255; OCR0A = 255; } // channels high, coast
// ============================================================================= =
You see my instuctions for running and stop the engine different (counter instructions) to the code in the users guide (page 12); similar to :
9. Motor Driver Truth Table (for TB6612FNG)
// Motor12 (0A/0B) Motor 34 Motor-
// PD5 PD6 PB3 PD3 M1A,M2A M1B,M2B effekt
// T0B-OC0B T0A_OC0A T2A-OC2A T2B-OC2B
// H H H H L L brake
// L H H L L H forward
// H L L H H L reverse
// L L L L OFF (high impedance) coast
Do you have any idea why ? I think its the effekt of the gearbox, is this right?
Thank you in advance for any help
