Re: 16F886 & 18F2620

Hi ron, i think all you have to do to get your internal 8mhz is to just use the configuration data as is shown in the post. I cannot test how much data you need to copy from that post yet, as i have not got the chip myself yet. The reason for the PLL part is because i wanted 32mhz and sean added the...

Re: Forum Suggestion: Need Categories

It's a good idea, but I'd personally be reluctant to do this because someone (i.e. Ben, Sean or me) would have to sort out the messages and put them into the correct place. Our time should be taken up with developing/updating products and answering posts, rather than administering the forum. Hi guy...

I don't think the changes will be too seriou...
