hiii........everybody....i want to control motor with TI 6713 DSK.I think i can do it...with by configuring McBSP pins as i/p.is it possible n can i drive a 6v dc motor with it?? plz..help it's urgent

If you need to source 0-6VDC to control the speed, forget about it. The McBSP as GPIO only gives you 0 or 3.3V with some tiny amount of current. Now if you want to supply a switching waveform to a PWM motor driver, controlling sweed by duty cycle, the DSK might be able to do that. Here are some example circuits for 3.3V: http://www.picotech.com/applications/pwm_drivers/index.html John John

hi, i could not make out exactly what information you require, but do see google for "power high side switch". this is also called a latch sometimes. the technical name might not be either. an example is bsp742t. this would solve the problem that john had mentioned in the previous post.(3.3 v output to a 6 v motor). in case the input is logic high, it will switch on power to the load. but integrating it straightaway with your dsk would require some research. there might be surge/impedance problems. i think a simple microcontroller would be an easier solution than a 6713 dsp. aps>hiii........everybody....i want to control motor with TI 6713 DSK.I >think i can do it...with by configuring McBSP pins as i/p.is it >possible n can i drive a 6v dc motor with it?? >plz..help it's urgent >

Well designing/making a transistor amplifier circuit is surely difficult and i dont understand what you mean by motor drivers with transistors. i do not know more about motors but i think they require a lot of current when they start. the gpio anyways can give 3.3v and the power might not be sufficient to start/run the motor (might damage the dsp)
