rev1 schematic wrong crystal value #2

Open ObviousInRetrospect opened 4 years ago

ObviousInRetrospect commented 4 years ago

I Built a rev1 an discovered that the schematic shows a 8mhz crystal but the firmware is configured for a 16mhz crystal (which matches the jpeg). No source files in the repo so I can't easily send a pull request with the correction.

Attaching a patch to configure the mcu for an 8mhz crystal in case anyone else repeats my error (having fixed the problem in software I wasn't motivated to replace the crystal). 8mhz.txt

Would you consider adding at least the schematic and preferably the design files for rev3 to the repo? It's a nice keyboard. Given the components that lack silkscreen it would have been easier to assemble with access to the board files.

Sorry about this @ObviousInRetrospect ! I didn't have enough 8MHz crystals so I switched to 16 MHz crystals at some pint.

It's a very important call out so I'll leave the issue open for anybody else that follows your path.

also let me fix the missing schematics. another nice call out.

nicolai86 commented 3 years ago

the design files for rev3 are already checked in - if you refer to the gerber files. I can send you the eagle files separately if you like.
