HPWM fails...

[f_lez]

Well not fails, but seem to behave odd...

if i create a simple for-next with a byte variable and out it the channel 1 or 2, with led's connected, the leds raise in brightness 3 (yes three) times for the loop!

I am using USB with DT interrupts, and ADC on ra0/ra1, idea was the adc value of ra0/1 woul;d pwm the outputs on channel 0/1



Is there any defines I should be looking at etc or anything else i can post to help?

18f2550, at 4mhz, pll div 1 OSC 48 etc.

DEFINE HSER_RCSTA	90h
DEFINE HSER_TXSTA	20h    ; 24 is giving error
DEFINE HSER_BAUD	9600
' DEFINE HSER_SPBRG	25  ' let picbasic set it from the baud def above
DEFINE HSER_EVEN	1

DEFINE CHAR_PACING 1000   ' slow things a little

DEFINE HSER_CLOERR  1 ' automatic clear overrun error



DEFINE ADC_CLOCK 1
DEFINE ADC_BITS 8
DEFINE ADC_SAMPLEUS 10

ADCON1 = %10000011 ; not sure lol
CMCON = 7 ;  Disable Comparators

INTCON2.7 = 0 ; should enable portb pullups.


for tempx=0 to 255


HPWM 0,tempx,1000
hpwm 1,255-tempx,1000

portb=tempx

pause 125
next

maximu brightness is at 87 and 174, not 255....

any ideas what could be causing this looping?


edit: user error, time to RTFM...

freq too low for clock speed...
