MSP430FR2633: Captivate Development Kit - Use 32 pins instead of 16 CAP pins only

Part Number: MSP430FR2633

Hello everyone, 

I built a touchpad with 8X8 rows and columns for mutual capacitance measurement.

I was wondering if is it possible to use the same development kit but with 32 pins (first and second pin rows, see image). It would be great to build a 16X16 capacitive grid.

Regards,

Gilberto Loureiro

    Hi Gilberto,

    The MSP430FR2633 has 16 CapTIvate IO so the most you can achieve is an 8X8 mutual capacitance setup (64 buttons). To achieve a 16X16 array you would need 32 CapTIvate IO and TI doesn't currently offer anything this large.

    Best regards,
