current limiter and stepper motor ramp generator

[badai]

hello guys.

i am doing stepper motor control for position and velocity( ramp generator) .i am using 8051 as the microcontroller.

anyone know how to construct ramp generator for stepper motor?

how is the connection then? does it an external circuit to the motor or it has to be connected to my 8051?

a simple current could be use the, how the circuit is and how to connect it?

You actually have to add delays in between the data bits sent to a stepper as it is not able to work at speeds as fast as a computer or microprocessor is able to send data. So when you want to change the speed, you just change the amounts of delay in between the step bits.
