I am using a 10F222 6-pin device to simply generate a tone when trigger input is high. The tone is adjustable by using an analog input simply tied to a 10k POT between 5V and ground. The 10F222, being a simple device does not have any PWM so I am limited to using the sound command to generate the tones. The tone range is good, but the sound is very choppy because the sound command requires a start/stop time limit. I need a smooth constant tone for the entire duration of trigger being high. I would like to use a 10F322 because I would be able to take advantage of the built in PWM output to generate the tone, however PicBasic does not support this device. I am looking for someone who could help me convert this simple PicBasic code for the 10F222 to 10F322 MPLab C code using the PWM register to generate the tone. I have tried to figure out MP Lab, but I am not getting anywhere with it.

Code:
@  __CONFIG _MCLRE_OFF & _CP_OFF & _WDT_ON & _IOFSCS_8MHZ
 
DEFINE OSC 8 

GPIO = %0000
TRISIO = %00111101
ADCON0   = %01000001	' GPIO 0 = Analog, ADC Enabled

SPK      VAR  GPIO.1    ' GPIO1/ANA1/PCLK
Trigger  VAR  GPIO.2    ' GPIO2/T0CKI
'        VAR  GPIO.4    ' GPIO3/MCLR/VPP 
  
Tone     VAR  byte 
GO_DONE  VAR  ADCON0.1	' Alias to GO/DONE bit for ADC
  
Main: 
   GO_DONE = 1		    ' Start the conversion
   IF Trigger THEN       
      Sound SPK,[Tone / 4 + 50, 1] 
   ENDIF
   WHILE GO_DONE : WEND	' If trigger isn't 'on' wait for the ADC.
   Tone = ADRES
Goto Main
