Can mutual capacitance detects "multiple button touches " in a 64x64 matrix? i.e: in a design like that: TIDM-CAPTIVATE-64-BUTTON 64-Button Capacitive Touch Panel With TI Microcontroller With CapTIvate Technology Reference…
Hi Bart,
Unfortunately, it may be difficult to achieve reasonable results with only the 4 Captivate pins. You are probably already familiar with TIDM-1021, Liquid Tolerant Capacitive Touch Keypad Reference Design , (I'll share the link for other readers…

Part Number: TIDM-1021 Hello,
Can we make more than 15 buttons with driven shield for water proof ?
Captivate supports up to 64 buttons with mutual capacitance method, but when driven shield is applied like TIDM-1021,we can make up to 15 buttons(TX:15…

my goal is to develop a waterproof capacitive touch-sensor.
In many sources on the internet, it is said that…
Hi Dennis,
Thank you for your reply.
When looking at TIDM-1021, RX traces is hidden behind the board and just above the front seems to be hatched with TX.
My idea's concern is that the RX trace will be exposed on the touch surface and will falsely detect…
Hi U-SK,
Making the LED holes larger will impact the sensitivity of the button. The less copper sensor area there is to interact with a person's finger, the more you will have to increase the sensor's sensitivity to compensate for this. One solution…
Hi Kz777,
Kz777 said: Is it able to use "MSP430FRAM series " as host MCU ?
It's possible but it is not currently supported. You may want to take a look a this TID MSP430 + CC2640 SPPBLE http://www.ti.com/tool/TIDM-CAPTIVATE-REMOTECONTROL It…
Part Number: MSP430FR2633 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…
Hi Cash,
I am using TIDM-CAPTIVATE-64-BUTTON Software -> Basic Demo code that i get from the Ti sites there have a UART Interface but I'm not getting proper data from uart. Even without touch of keypad (CAPTIVATE-64-BUTTON) it continuously sends…
