// What does our keyboard matrix look like?
// If MATRIXCOLS*MATRIXROWS exceeds 255, you'll need to do some work on
// the types used in the scanning loops and probably change the uint8_t
// casts on these definitions to unsigned short int.

// Columns are those things which we strobe
// If this exceeds 256 things will break all over the place
#define MATRIXCOLS ((uint8_t)(16))

// Rows are those things we read the results from
// This needs to be the length of an integer of some sort, and you need
// to typedef a kbdrow_t to an unsigned type of the right length.
// If you have a funny number of rows round this up and just ignore
// those bits (set to 0 on kbdSampleRows, 0x00 entries in keymap.h
