Actually my project involved Beaglebone B and I have completed other
features on it. BTW, I need to control 4 BLDC motors
Thanks vern!
Got your point. Any PWM controller IC that can deliver frequency in the
range 8 khz to 20 khz will fulfill my requirement. If I get that IC, my
problem is solved for PWM channels. Also, I don't wanted to go costlier by
using motor controller ICs unless no choice.

If you want to control a BLDC motor, then the PWM frequency should normally
be in the range of about 8 KHz to 20 KHz, fixed frequency. The TLC59116 is
not for controlling BLDC motors. The important features when selecting the
controller are Voltage and Current. Small motors may operate at 12V /

Hi jmelson !
I am making my own cape.
I have found one PWM controller (TLC59116) from
TI http://www.ti.com/lit/ds/symlink/tlc59116.pdf
but it says individual channels are adjustable but with a fixed frequency
of 97 khz. Would that be enough or adjustable frequency is a must feature

All ICs I found, have fixed frequency with variable duty cycle. I think
programmable frequency with variable duty cycle is must to drive BLDC
motor. Is that right?
Can you please suggest one IC.

Mr David,
Thank you for the valuable comment.
I was looking whether I could make use of the available GPIO pins. If not
I will have to go on with your idea of the separate PWM ICs and interface
with the processor. I will have to look for more info in the internet.

Thanks TJF.
Presently I am using am335x_pru_package library. I will see whether it has
example programs regarding accessing ADC pins.
