MSP430FR2633: MSP430FR2633

Hi Shivam,

Use the CAPTIVATE-BSWP project included with the MSP-CAPT-FR2633 design files. Or expand the OneButton project's ButtonGroup to include the other 7 buttons (self capacitive, RX00 through RX07 on CAP0.0, 1.0, 2.0, 3.0, 01., 1.1, 2.1, and 3.1, respectively)

Hi Ryan
I am using this program to control 1st button of BSWP to ON/OFF LED2. what changes should I make in this to use say Button 2 of BSWP to control LED1. please help me with this as soon as possible

Hi Shivam,

First, I used the CodeSizeOptimized_OneButton-Demo CCS project but copied/pasted the captivate_config folder of the CAPTIVATE-BSWP-Demo project so that all 7 button elements were defined.  Here is a quick demonstration of how to perform the functionality you are asking for:

hey Ryan

Thank you man, it was very Helpful.
