Where is the shift?

A project log for Samsung NP540U4E to BLE keyboard conversion

I always wanted to have a wireless keyboard with touchpad. Preferably with Bluetooth. So I have started to build one.

I have successfully mapped my layout, but only two keys are missing:

the left and right shift.


The keymap looks fishy: the column 0 is unused.

- All rows are functioning

- MCU output checked

- MCU to connector checked

- I have peeled off the adhesive glue from the keyboard connector, and was able to verify the connector -> keymatrix connection.
