| lpc2103: PWM for Stepper Motor |
| (1/2) > >> |
| s.mosfet:
I should control 2 Stepper Motors with the LPC2103 microcontroller (ARM). It supplies: - 4 timers - each timer can produce 3 PWM signals. The problem is that i should produce 4 PWM signals to control the motor with 4 phases (see pic)... How to do this? |
| mikeselectricstuff:
You wouldn't use PWM mode as you want to control the position of both edges. The set/clear on match functions are probably useable for this if there are enough pins. |
| Alex:
Are you allowed to use external ICs or you must only use the NXP MCU? |
| JohnS_AZ:
You wouldn't use PWM unless you wanted to microstep the motors. Plain digital outputs into a driver transistor should do fine. |
| s.mosfet:
i would use only the MCU (and a driver IC..) .... Can i use the PWM outputs to make these types of signals? or i must create it with the code? |
