Hi, I am using dsPIC30f4011 microcontroller. I am trying to determine the internal clock of my microcontroller by using TIMERs.
(I am using XT PLL x4 with 7.37 MHz as my external clock)
Basically, I am just trying to output a PWM signal that SHOULD correspond to the internal clock of my microcontroller. From computations, I should have an internal clock (Fcy) of 7.37MHz through using the PLL 4x. But when I check the frequency of the signal using a oscilloscope, I am only getting ~82kHz. Please tell me if I'm doing/assuming something wrong with my procedure. Thank you very much!
