12F675 cant serout to PC

[ruijc]

I have tryed that but if i use that line it does not work ( doesnt send data nor the led in gpio.2 blinks )

.

what happen if you change MCLR_ON to MCLR_OFF?

Are you sure it's a 4MHZ crystal?

Can you measure it with a scope?

I'm not using any Max232

About the MCLR, when on i hooked it to vdd, also tryed off and result is the same.

The caps for the xtal are both 22pF

I'm using the Serin program to get the data from serial

.

i can try using the internal osc...but will have to use MCLR on or i will lock my pic :S

IC-Prog has 2 choices...

INTOSC GP4

and

INTOSC CLKOUT

which one may i use ?

AH CRAP, i really need new glasses... so just change your SEROUT2 baud constant to use inverted mode... and it will work

baud	Serout2
----	-------
9600 	16488
4800 	16572
2400 	16780

with 1-10K resistor in serie, this have to work.

I would suggest you to use DEBUG, it use less code space and may work on higher baudrate with slower crystal speed.

The SEROUT2 baud constant table did not worked as well...

but...

using DEBUG worked 5*****

I guess it's because the low speed xtal

Thanks once again Mister-e
