In desparation I tried a second MCU, +but had the same problems. It turns out that the ribbon cable connections can get worn. Shave a +half millimeter off the end of the ribbon cable & the errors go away. + +My method for discovering the matrix was to set up a LAYOUT macro that included all pins. +See MATRIX_TESTING_LAYOUT if you need it. Then set up a keymap that has all printable symbols +in the first 4 rows. test each key & record output. Then switch the printable symbols to the +bottom 4 rows & repeat.
