Interesting solution temtronic - thanks.

Hope the weather isn't too bad where you are? It's just cold and wet in old Blighty where I am.

Hi Guys,

I've a project which requires the use of multiple PICs (18F46k22 and PIC16F688) on the same PCB. I need the PCB to be as small as possible, but don't want to have to provide a programming ...

The array you show in your example will use fully 3/4 of all the SRAM in an 18f4620 , whether it is used as shown or crammed into a single dimension of

Yeah sorry about that, I just typed some n ...

Hi,

Is there a reason to use a multidimensional array over a single other than just good readability of code? Are they stored differently in the PIC?

Also, I have read that when using a multidi ...

My old boss told me to never have IO pins going straight to connectors; always series with a protection resistor to prevent ESD problems etc.

Also, he never trusted tantalum caps as he knew about t ...

Also the reason this error will occur is if you haven't specified the correct UART Hardware pins!

Make sure you change these when porting code from one Pic to another!!

Hmmm... Reminds me why I've not tried it before! I think I will take a gander at the assembly listing like you suggested Ttelmah and try to glean information from it. I think I'll take the plunge at ...

This is a pretty fundamental question, but I've wondered for a while and although there examples of how to use it, and the pitfalls involved, I'd like to understand the usage of Global Interrupts a bi ...

For interest only, I've successfully long term tested up to 3mbps (3 megabaud), between two 18f4620 pics using their internal UARTs over 250metres of cable (using a proprietary driver system).

Thanks guys,

I do sometimes struggle to understand some of the microchip datasheets, so it's great to get a second opinion.

:-)
