Clock Question - New to PicBasic

[paul borgmeier]

The 819 has the ability to be run at several different clock speeds when using the internal oscillator option. Did you set up the OSCCON register? If not, take a look at the 16F819 data sheet, section 4 for details. Post back if you need more information.

Paul,

I got some time to look around following your advice, searched to forums for OSCCOM. Quikly found out that it was a non-PicBasic command.

A hour searching the 16F819 data sheet got me the command, the address and the register description.

The command POKE $8F, %01100000 got me 4MHz and a correct blink rate.

I guess I'm going to have to learn some assembly whether I want to or not.

Thanks for the lead.

I'm hoping that I'll have better luck with PicBasic (ie using it as a high level language, rather having to hunt around for register addresses). If I end up doing too much assembly level crap, it will kind of defeat the purpose of using PicBasic. We shall see.....

Alan,

Nice work! - With PBC, you need to find and deal with register addresses like you did. With PBP, you do not (as much). Again, good job.
