I need to make a four phase signal, I would like to be able to do this with a PIC like the 16F690.
Frequency is app 40kHz. Duty cycle and frequency is important, I need the PIC to perform other tasks as well so i need the PWM block, I dont have bandwidth in the processor to bitbang this pattern.
It is difficult to see if this operation is possible with this processor. If not any sugestions for a similar processor with this capabillity ?
The four phases have 25% duty cycle, and should be 90dgr seperated,
