Hello everyone,
I am new to MCUs. I am developing an
application where I need to pulse width modulate (PWM) a square wave of
120 KHz fundamental frequency. The duty cycle increases/decreases in
steps of (1/256) (8-bit precision). For this, the master clock driving, 120 KHz square
wave has frequency 120*256 = 30.72 MHz. I have gone through TMS320x2833x enhanced PWM datasheet (SPRUG04A). If I use TMS320F2823x, I have CPU system clock up to 150 MHz. The document (SPRUG04A) gives me an impression that I can do PWM at 120 KHz (with 8-bit precision) using TMS320F2823x. Am I correct to say this?
If not, is there any MCU/DSC
(16-bit or 32-bit) by which I can do this?
I guess I posted my query in a well understandable way. It would be a great help if anyone can provide pointers on this.
Thanks
Abhishek
