Using the PIC16F818/819

[mat janssen]

When using the PIC16F818 or PIC16F819 with internal rc clock.
You need to add a line extra for propper working of the device.

Here is an example:

@ DEVICE INTRC_OSC_NOCLKOUT,MCRR_OFF
DEFINE OSC 4
' and now the extra for propper working

OSCCON=$60
'70=8MHz, 60=4MHz, 50=2MHz, 40=1MHz, 30=500kHz, 20=250kHz, 10=125 kHz, 0=31,25 kHz.

When you forget this the divice is not working in PBP

The 819 chip will work without the define, but the Osc is in the slow speed mode... You just have to have a lot of patience for your chip to do its job.
