I am working on making a copy of the axis-64. It is based on cherry MX switches, I am using a different method to achieve the velocity sensing. See the attached diagram:
So far I have used din_velocity_unmuxed_v1c.zip for software and have achieved good results, but this project is limited to 64 keys. I have seen the fast scan project for the 32 bit core, but even that project is limited to 128 keys. Does anyone have ideas for achieving 192 keys (384 inputs) or is this not feasible for a single core?
