How do I create a microcontroller board (using the parts editor) that has more than 64 pins? Neither the generic ic or the mystery part allow more than that.
There is indeed currently a hard limit of 64 pins. For now you would have to find another part with more pins--for example one of the larger Arduinos or something in the Sparkfun library.
The Arduion Mega seems to have the most pins available, but the part I'm trying to make has 98 pins- 16 more than the Mega. Is it possible to add more to that, or would it be more advisable to wait until the new parts editor is completely release?
Your post requires multiple answers.
-- We will bump the allowable number of pins on mystery parts and generic ics to 128 in the next release, which is due out probably in the next week or two.
-- The next big revision of the parts editor is probably not in the cards until Q3 2013.
-- Though it is indeed is a convenient way to get started making a custom part, it is not necessary for you to wait for a 96 pin part to be available. It is "only" necessary that you create or modify three svg images (breadboard, schematic, pcb) containing structures (i.e. svg elements) which are used to make up connectors.
To be less abstract about it, in breadboard and schematic view, these structures are typically <rect> elements, and in pcb view these elements are typically <circle> elements. In the context of other forum posts I have seen that you are quite adept at using Illustrator, so this is where you would create these elements.
There is a complication, which is that the elements have to be grouped, and the group has to be given an specific ID (i.e. "breadboard" or "copper0"), but you are also already familiar with this.
So it's up to you whether to wait for the next release. If you choose to go forward immediately, I have the following suggestions:
Has the number of permissible pins been bumped up yet?
Never mind, thanks!
Yes, bumped to 128 pins in the latest release (available for download since yesterday).
