Help on PIC16F767

[Acetronics2]

Hi, Rony ...

Could you, please, provide your program header ??? ( ALL configs + pins assigned )

i think it is not stoping, but it is going very very very slow.....

[Rony]

i forget to say:

i changed the Oscillator, i tried with a resonator, i put a 100nF on the + and - very near to the PIC, i tried with 8MHz ... without sucess

[Rony]

i am using the following:

@ device pic16F767, hs_osc, wdt_off, pwrt_on, protect_on, mclr_off

lvp_off is not applicable with this PIC

=> same problem

[gadelhas]

i am using the following:

lvp_off is not applicable with this PIC

=> same problem

You're right, confused with 16F876.

[Rony]

Finally i found it,

"gadelhas" remark lets me think about the configuration ... thank you

there is a check box called "FCMEM" in the WinPIC800 programmer, when turning it OFF, it works, and all the rest will not affect this problem.

anyone knows what is this "FCMEM" that it must be off ??

thank you for all.

Well Done!.....

HI;


Try put this on the header, before the oscilator Define, and them test!
@ __config _HS_OSC & _LVP_OFF
