Fuses Again

[jcleaver]

as it seems i have to go beyond pbp to get certain programs to work

damm fuses again

i am trying something very simple to start the training

chip 16f627a
assembler mpasm

trying to set chip for external osc because most people say this is required to run serial communications

tried the following statements
@ device xt_osc

@device pic16f627a,xt_osc

@_config_xt_osc

_config_xt_osc

all commands generate error messages in a simple 4 line program which assembles fine without the commands

wish pbp would include these setups as part of the compileing

Have a look to the following. Everything should be covered.

mister e
thats where i went to get started seemed simple enough
however all the commands shown see above
generate a error

[mister_e]

errors or warning.. that's the question!

tell me

1. the error number your program return e.g. Error[118]c:\... Overwriting previous address content (2007)
2. MPASM version
3. PBP version
4. your config line
5. the modified .INC file in your PBP folder.

Here, PBP 2.47, MPASM 5.06

        @ __CONFIG  _INTRC_OSC_NOCLKOUT & _MCLRE_ON  &  _LVP_OFF & _WDT_OFF & _PWRTE_ON  & _BODEN_ON

and the 16F627A.INC file

Computers are stupid, PICs are stupid, they are not however, sloppy. So when they want some piece of code they will not accept a peace of kode, because they are stupid.
Now look at mister_e's code, the word config is preceded by __ not _ , that's two little Hyphen slash thingies, not one.
I hope this helps.

pbp 2.46 mpsam 5.


errors 113 and 118 are listed when i try the first line above


this is warning with the second part above

post your whole code... and make sure your MPASM PATH is right and MPASM is checked in the Compile and Program Option> assembler tab of MicroCode Studio.

only getting overwriteing previous address error now is that ok


also your first line did not give xt-osc which is all i really am trying to start with

attached file

mpsam is working perfectly expect when i try fuses

[mister_e]

sorry, i misread your first post. Anyways, you'll need this one

@ __CONFIG  _XT_OSC & _MCLRE_ON  &  _LVP_OFF & _WDT_OFF & _PWRTE_ON  & _BODEN_ON

[jcleaver]

thanks that seems to work except for the overwrite error
is that a problem??

Hi Jack,
Look at post #4 in this thread. Mr E. explained what to do to eliminate the last error of which you speak. The compiler sees the config default settings in the INC file and then sees the config setting in your code, and guess what it does?
It ignores the setting in your code and goes with the default. So just add a semicolon ahead of the two statements he showed you and the compiler will forevermore do what you tell it for this chip. You will have to edit each individual inc file as needed. So why is that statement even in there? Did you ever compile a program without setting the configs? Did it work? Yes it probably did if you used a 4mhz chrystal, because of the default configs.

[keithdoxey]

Just a thought....


...now that we mostly work with Flash devices rather than OTP, shouldnt we be referring to "Configuration Circuit Breakers" rather than "Configuration Fuses" because we can reset them.

[jcleaver]

joe thanks for the info i guess what you are saying is i need to find the
inc file for this chip and rem out the config statement so it writes it according to my programs

the problem, which i had earlier and never really found a answer is i am not sure where it is looking for these files as i have many inc files for this chip
got installed with some programmers and mpsam so really dont know which file to use.
if i try the first part besides getting the error of overwriteing it will not go out to the programmer

also if i try to use the second part of posting #4 i get huge errrors see my later listing
so basically niether statement works for me
must be a simpler way

thanks

jack

We talk about commenting the PBP default ones. THE .INC file is located in the PBP folder.

What I am really saying is despite my inability to spell crystal properly, follow mister_e's instructions and you will be right 99.9999999062 % of the time, He will never intentionaly lead you astray! Same with most all of the other " BIG GUNS" in this forum same applies to BIG 'UNS too . I wish he was an investment counselor !

might want to take a look at mikroelekronika there assembler and programer
make duck soup out of working with fuses just check off like a list
looks very simple
