I need a clock signal for the LT8500 pwm chips and it would be nice to use the clock output on the beaglebone rather than an external oscillator. My guess is that it runs at the 24Mhz clock on the beaglebone which will work for the LT8500s but I don't really care what frequency it is for my application. I'm driving DC motors so a few kHz is all I need really. The LT8500s divides the clock frequency to create the PWM frequency. For example, an input of 25Mhz gives a 6kHz PWM signal on all 48 outputs. Just out of curiosity,
1) Is the clock frequency configurable? 2) Can any of the GPIO pins be configured to produce a clock signal? 3) If so, what frequency ranges? 4) I read somewhere about timers. How do those work? I quickly searched the Technical Reference Manual but I didn't see anything about the clkout2 pin or the timers. Is there another reference I should look at?
