max frequency on pwm channel 16f88

[rmteo]

What is the max frequency output on a 16F88 MCU on PB3 (ccp1), the PWM output? Tell me I can go to 38000Hz.

Very simple, just check the data sheet Table 9-3.

Hi,

In the PBP3.0 manual there's a table that shows max frequencies for given oscillator frequencies. For 8Mhz oscillator, this is 489 Hz. Is this true?

No, the table in the manual lists the lowest possible frequency obtainable using the HPWM command at the given oscillator frequency.

/Henrik.

Thank you all! I can't believe I've been misreading the PBP3.0 manual wrong all this time regarding the LOWEST usable frequency. It is NOT highest. And there in the spec sheet, in table 9-3 which I've not seen before (because I was just letting the HPWM command take of stuff), is a table of frequencies.

I'm on a roll.

Thanks again guys.

BTW, the numbers in table 9-3 are not the highest PWM frequency that the PIC can attain. It can reach much higher frequencies than those stated - depending on the resolution you want.
