Other Parts Discussed in Thread: CAPTIVATE-FR2633, TIDM-CAPTIVATE-64-BUTTON
Hi, I am designing capacitive touch keypad using MSP430FR2633.
I wanted to inquire if I have to connect resistors of 470k at processor side along capacitive channel as shown in pdf document CAPTIVATE-FR2633_REV_C_Schematic or will it do without resistors?
Also is it necessary to connect capacitors of 33pF at processor side along capacitive channel as shown in ALTIUM schematic file TIDM-CAPTIVATE-64-BUTTON?
I am confused if to connect capacitor or resistor as both document differ slightly.
Thank you.
