help re pbp3 and picket 2 with 12f675

[musturdi]

hi,

i am a beginner and use cannot get any program to run

i have compiled this and it complies fine, when i load the Hex file into mpelab it programs the chip but it does not run on my breadboard help

hi sorry i should have added what config bits do i set to get this to work ? i am confused with these

regards judd

[Acetronics2]

Hi, Judd

May be you could

1) add

DEFINE OSCCAL_1K 1

@ the top of the code

2) Giving the link could have helped so much ...

http://www.rc-float-flying.rchomepag...w%20Driver.htm

shows the config is missing for GP3/MCLR ... used as an input

so, also add @ Top for PBP3

#CONFIG
 __config _INTRC_OSC_NOCLKOUT & _WDT_ON & _PWRTE_ON & _MCLRE_OFF & _CP_OFF & _BODEN_ON
#ENDCONFIG

Alain,

Many thanks for this i wil try later and sorry for not including the link new at this as well
regards judd

[musturdi]

hi

see the ask below this complies and the hex file will program to chip, but it just will not run any suggestions?

If you added the LED back in, you would be able to trouble shoot it better.

What happens if you just load the straight hex from the code example that Acetronics links to:

[Acetronics2]

Hi,

movlw 0Ch ; Set GP<3:2> as inputs

It works so much better with Port2 set as an output ....

Alain

[ScaleRobotics]

I think the original author of the code is confusing pins with port names. His drawing shows glow coming out pin 2, (GPIO5), but his code shows it coming out pin 5, GPIO2).



GLOW VAR GPIO.2 ;Output to MOSFET driving glow driver - Pin 5
RADIO VAR GPIO.3 ;Input from receiver - Pin 4

[Acetronics2]

+1 !!!

Works fine using GP2 ... as the output.

BTW, this design is carbon14 dated ...

Alain

[musturdi]

hi all,

thank you all for comments and help

i have followed Alains kind advise, and if i leave out the osscal 1k 1, it works, think the pics i am using have lost the oscal setting!!, Ordered some new ones

Alain adding the config statement got it working thank you very much.

what does carbon 14 dated mean?. Do you have a better bit of code to do this? i would be grateful for any help i am a complete beginner at this, thank you in advance

i did try to load the hex file but that did not run either.

but i have finally got this working?

thank you all it is very much appreciated

regards

[mister_e]

In this case, Carbon 14 dated mean it's been made several thousands of years ago

[musturdi]

Alain,

thank you old but does the job.

a bit like me

regards
