Hey guys,

I used Capsense self-cap to made a force sensor (sandwich structure), on electrode pad as the self-cap pad, another one connected to the GND. It works very good, but now I wanna make a 5x5 sensor array, so I set 5 Buttons(0~4) in CSD (self-cap), and a MUX for other 5 GND Pins.

So I used this code:

But the problem is, I can not just use "uint16 Value0 = CapSense_dsRam.snsList.button0[0u].raw[0u];" to save the data now, cause I just have 0u, 1u, 2u, 3u, 4u, but I need read out 25 data.

If I use Mutual-Cap then I can set 5TX and 5RX, then I can get 0u to 24u. But what should I do with Self-Cap?

CapSense itself supports Matrix Button widgets, I suggest you to read the datasheet of the CapSense component first to get a general idea of CapSense usage, it will save you a lot of time later on. Right-click on the CapSense component and you can choose to open the component datasheet.
