Hi All,

I am looking to generate a continuous 50Hz sine wave output using the FREQOUT command.
From the "good book", the command is FREQOUT, Pin, Onms, Frequency1, {Frequency2}
My initial idea was to set the Onms equal to zero to achieve continuous operation however this does not work (only operates for ~66 seconds).

Here is my trial code using PIC12F615:

Code:

    Freqout GPIO.0, 0, 50
	GPIO.0 = 0       ; Set pin low to capture rollout of command execution
	PAUSE 2000     ; Pause 2 seconds to accentuate rollout capture period
GOTO Main

END
Any suggestions how the FREQOUT command can be structured for continuous operation?
