Hi all,

Ive got a small problem with a DS1820 setup.
Iam using a 16F819 with its internal osc at 8mhz.
I have modified the onewire.bas so as to send the data serially.
My display simply reads 85.0 C constantly. It doesnt alter when temperature is applied either.
Occasionally it will read 26.89 C but only briefly and only just after power up.

My question is, is timing accuracy critical on these?, What am I missing?

Iam currently unable to put an LCD module direct to the PIC.

Iam running a serial LCD module.

Hope someone can ppoint me in the right direction.

Regards

Darryl
