#90574 - Sorry, after testing, still have problem Responding to: ???'s previous message |
I still have problem printing data in the printer.
First of all, i don't know why the motor rotate in a wrong direction, i have tried to reverse the sequence of the ouput signal of KA3100D with P_SIN_1 is the input of IN1 of KA3100D P_SIN_2 is the input of IN2 of KA3100D clr P_SIN_1 ;step 3 clr P_SIN_2 call DELAY_M setb P_SIN_1 ;step 2 clr P_SIN_2 call DELAY_M setb P_SIN_1 ;step 1 setb P_SIN_2 call DELAY_M clr P_SIN_1 ;step 4 setb P_SIN_2 call DELAY_M for 3->2->1->4 or 4->1->2->3, the rotation is also wrong. And i dont understand the relationship between the motor and the printer head's LATCH and STROBE pins. I dont know which one should be fired first. if a dot line need 2 steps of the motor. then i should moved 2 steps and stop the motor, then fire Latch, clock in the data and then STROBs, then clear the STROBs, and next 2 steps? Thanks |
