Read the newbee threads, 16F877A no go.

[BobbyA]

Hi Melanie,

As I said I'm a newbee to PBP, and it's still not clear to me the purpose of the c:\PBP\INC\M16F87xA.INC vs. the C:\PBP\16F877A.INC file.

I do know the suggested fix was to edit the xt_osc to be hs_osc in light of the clock speed used, and to check the Special Features section of the datasheet. While in the PIC datasheet I noticed there were other configuration bit options that didn't have entries in that file.
So I stand by the statement, "the datasheet calls out many configuration bit switches that are not addressed in the c:\pbp\16F877A.INC file, when using PM."

Maybe they don't need to be there, I'm not well versed yet on the effect each configuration bit has on PIC performance. I have to assume if they were not included in this file they are not critical for simple functioning, same with an initial set or cleared condition. This may yet lead me to grief.

BR,
Bobby

Going through the forum posts, I encountered the same problem as in Post#21 above.

Here is the simple code trying to write to DS1307.

Start:

I2CREAD PORTA.3,PORTA.2,$D0,0,[0,0,0,0,0,0,0]

GOTO Start


END

I get;
ERROR Line 16: Expected '['. (Untitled8.pbp)
ERROR Line 16: Expected ']'. (Untitled8.pbp)

No variable or alias; just direct values...

What is the cause of this issue?
me?


Thanks.

Aw c'mon Sayzer, that's a no-brainer...

Too much wine, women and song this festive period...

You're trying to READ from a device, and then attempting to store that data into a series of CONSTANTS??? Maybe that's where CONSTANTinople comes from...

I prescribe a large mug of Turkish coffee and a code revision to something like...

	dA var BYTE
	dB var BYTE
	dC var BYTE
	dD var BYTE
	dE var BYTE
	dF var BYTE
	dG var BYTE
	
Start:

	I2CREAD PORTA.3,PORTA.2,$D0,0,[dA,dB,dC,dD,dE,dF,dG]

	GOTO Start

	END

Alternativelty swap IC2READ with I2CWRITE if you are really intending to WRITE.

Happy Holidays everyone!

What can I say?

I wanna cry :'(
