PICBasic newbie problem

[ELCouz]

Yes, i have a printed pdf of this pic on my wall :P

I did read them before , the problem is ... how to write (declare) them in PICBasic this is my first attempt at picbasic , so don't bash me :P ?

It would be nice if i could write them (ex: FOSC = HS written in P18F4550.inc of MPASM ) instead of defining them with HEX stuff
Have a nice day!

Hi Laurent,

Welcome to the forum.
See if this previous series of posts from Melanie, mister_e and others, helps.

Thanks I've commented the Picbasic fuses in the include...

Fuses is ok but on compiling this code:

ASM
    CONFIG FOSC=HS    ; Use HS oscillator (20MHZ here)
    CONFIG BOR=OFF    ; Brown out reset ON  
    CONFIG WDT=ON    ; Watch dog timer ON
    CONFIG LVP=OFF   ; Low Voltage programming OFF
    CONFIG DEBUG=OFF ; Background debugger OFF
    ENDASM
led VAR PORTB.5
steps VAR WORD
cycles CON 2

' Change limits for steps to play around 0 or 100% brightness
' Change steps for different duration of ramps
' Works good even with high brightness LEDs, harder to control linearly


fade:

up:
For steps=0 TO 255
PWM led,steps,cycles
Next
High led

Pause 2500

down:
For steps=255 TO 1 STEP -1
PWM led,steps,cycles
Next
Low led

Pause 2500


GoTo fade

End

i receive many errors :


maybe it's the code that is faulty or it's something else ?

Could you show me a code that will ABSOLUTELY compile (and tested to work), ex: blink a led so i can start to debug the previous code , to see if its my compile that freaks out or it just a simple issue....


Many thanks!

Have a nice week!

Best Regards,

I just went through the same problems. See the thread below post#6 regarding editing the .inc file


http://www.picbasic.co.uk/forum/show...ighlight=fuses

[krohtech]

ASM
    CONFIG FOSC=HS    ; Use HS oscillator (20MHZ here)
    CONFIG BOR=OFF    ; Brown out reset ON  
    CONFIG WDT=ON    ; Watch dog timer ON
    CONFIG LVP=OFF   ; Low Voltage programming OFF
    CONFIG DEBUG=OFF ; Background debugger OFF
    ENDASM

I never did get this method to work. I use this method of setting the fuses on my 18F2410:

@       __CONFIG    _CONFIG1H, _OSC_INTIO67_1H
@       __CONFIG    _CONFIG2H, _WDT_ON_2H & _WDTPS_512_2H
@       __CONFIG    _CONFIG3H, _MCLRE_OFF_3H & _PBADEN_OFF_3H 
@       __CONFIG    _CONFIG4L, _LVP_OFF_4L & _XINST_OFF_4L

[Bruce]

Refer to post #20 in the above thread link. PBP still does not support the new style config directive without the double underscore.

You need to do it the old fashioned way as indicated in the above post by krohtech.

Thanks ! You fix all my problems !

However i have another question about this code and the function PWM...

How to have multiple pwms output ?

take a look to the following code

@       __CONFIG    _CONFIG1L, _PLLDIV_3_1L & _CPUDIV_OSC1_PLL2_1L
@       __CONFIG    _CONFIG1H, _FOSC_HSPLL_HS_1H
@       __CONFIG    _CONFIG2L, _VREGEN_OFF_2L
@       __CONFIG    _CONFIG2H, _WDT_OFF_2H 
@       __CONFIG    _CONFIG3H, _MCLRE_OFF_3H & _PBADEN_OFF_3H 
@       __CONFIG    _CONFIG4L, _LVP_OFF_4L & _XINST_OFF_4L & _DEBUG_OFF_4L
DEFINE OSC 48
led VAR PORTD
'changed WORD for BYTE ... using 32bit int for 8bit value is taking more cycle to do operation to it

step2 VAR byte
step3 VAR byte

step6 VAR byte
step7 VAR byte
cycles CON 2

' Change limits for steps to play around 0 or 100% brightness
' Change steps for different duration of ramps

fade:


For step0=0 TO 100
PWM led.0,step0,cycles
Next
For step1=0 TO 100
PWM led.1,step1,cycles
Next
For step2=0 TO 100
PWM led.2,step2,cycles
Next
For step3=0 TO 100
PWM led.3,step3,cycles
Next
For step4=0 TO 100

Next
For step7=100 TO 1 STEP -1

Next

GoTo fade

End

What i want is to fade ON all led each by each while keeping them ON
then after Turn them OFF (while fading) one by one

The code only do pwm on 1 led at time only :S

Any clues ?

oh btw, searching through the forum is PITA ... it doesn't take words like PWM , because it's too short ... hence rendering the search practically useless for "Multiple PWM"

Cheers,

How to have multiple pwms output ?

PWM is a blocking command. You can only do one PWM at any one time, PBP only has one 'hand' available to do PWM. You have to write good interrupt driven software to do multiple channels. Well, you don't HAVE to do anything. There are many ways to do multiple channel PWM, software based PWM...

Look in the FAQ's...

I use Darrel’s Multi SPWM code to get 8 ch of PWM at 100 Hz. Works GREAT (((thanks Darrel)))

Forgot about that one.
I've done it myself on an 18F8722 to the tune of 48 channels of LEDs at 40Mhz, refreshing at 7152.2Hz. Same principle, but relatively easily done. If you can do 2 channels, you can do 100.
