MSP430FR2111: MSP430FR2111 IO support Capacitive Touch ?

SeaFesse

Part Number: MSP430FR2111

Hello TI employee,

In FR2111 ‘s datasheet , it seems FR2311 support Capacitive Touch, however, when I go throuht the PORT schematic for details ,I see no oscillation circuit like G2303.

so I need your confirm, Thanks a lot.

FR2111 functional Block.

Hi,

The MSP430FR2111 supports capacitive touch. The FR2111 uses a different technology than the G2303 called CapTIvate and is why you don't see the same internal circuitry. You can learn more about it here: CapTIvate Technology

Hello Caleb,

As I know, Only MSP430FR26x2 、MSP430FR25x2 support CapTivate. MSP430FR2111 don't have CapTIvate Touch Module.

Hi,

I apologize, I got a little ahead of myself. You're correct the MSP430FR2111 does not have CapTIvate. However, I can confirm that all GPIO can be configured as capacitive touch IO as described in the devices datasheet. If you have any further questions let me know.
