CAPSENSE™ & MagSense Forum Discussions

Hi,

I had read somewhere that the configuration has to be saved in flash in MBR Device. Can you tell me how to do this?

Regards D

Good morning everyone, I have a system with Psoc4100S-Plus, VDDA at 5V and VDDD at 3.3V.
The CapSense block is powered by VDDA.
Why is the Tx signal for CSX mode 3.3V?
Can it be set to 5V of VDDA?

Hi,

I was was researching input methods/switches for desktop use and I stumbled across this device https://www.native-instruments.com/en/products/maschine/production-systems/maschine-plus/ . I was able to interact with this device and what caught my interest the most were the (presumably) capacitive pads (the 4x4 grid with big rectangular buttons). They felt super responsive and I wanted to try and make a keyboard using similar type of input. I am confused, however, as to what components I would need for that project. The ones i'm unsure about are the buttons (I had a look at the MBR3 evaluation kit but I can't tell how the buttons are construted) that would sit behind the block of plastic (or other appropriate material similar to the one on the maschine device - I do want these to protrude out similar to keys on a keyboard), the touch microcontrollers, and then microcontrollers that are collecting the output from these. Eventually I want to go up to a tkl design which uses 108 keys. I also care about latency and reliability so a 1kHz polling would be expected (although I would consider designs up to 10kHz).

I am completely green when it comes to pcb design so I'd appreciate any help

We have experience tuning PSoC1 and PSoC4 non-MAX ICs to sense through thick gloves or even 5mm+ of cover glass. However, we are still learning about the CapSENSE 5  capabilities found in the PSoC4 MAX. Using the Pioneer kit, I've been able to overlay about 4mm of cover glass on the touchpad found on the expansion board and still get good response, but haven't experimented further. Has anyone out there explored the limits of what's possible for sensing distance using the PSoC4 MAX? Anyone hit 10mm? Obviously, this will be dependent on sensor design/construction.
