HELP!! Interface 3 Stepper motors to work simultaneously?

[PRATYUSH RAJ]

How can we interface 3 stepper motors to work simultaneously alongwith a bluetooth module interfaced to 8051? Is it in capacity of 8051 to do this or is it not possible at all?

[Ashutosh Bhatt]

bluetooth module gives serial output

8051 has built in UART to get serial input

to get data from UART while motor is running is possible if you serially receive data in interrupt mode.

when data arrives interrupt generated. motor will miss hardly one pulse during this

My real concern is whether 3 stepper motors can run simultaneously through 8051? Consider each stepper motor to generate linear motion in each dimension..so my question is can 8051 be programmed to control the motors to cover each point (x,y,z) in its limit?

Good day.. actually i have no idea of the post i came here for help, i am a student of electronics and i just bought an 8051 programmer, i have very little idear about assemble language and little about C but not in embedded system.. please i need help on how to use C programming to programm 8051 microcontrollers.. thanks alot

I don’t think there would a problem, all you have to do is to select more output pin and write the required pattern of logic high and low for driving the steppers

[Ashutosh Bhatt]

not only 2 3 or 4 but you can drive maximum 8 stepper motors simulteneously using 8051. there is no problem

the stepper motors are having comparatively slower RPMs. so you can drive them with very small phase delay of 1-2 micro second. that is completely unnoticebal.
