Touch and Hold to register a touch about cap1298 HOT 6 OPEN

Afraid not! This library was only put together to test whether the CAP1298 was suitable for something I was working on - it wasn't. I didn't take it any further than I needed to, so most functionality is not implemented.

That said, you should be able to enable repeats with register CAP1298_RPTRATEENABLE (0x28), then fine tune the hold/repeat times in registers CAP1298_SENSINPUTCONFIG1 (0x22) and CAP1298_CONFIG2 (0x44). This is briefly described in section 4.9.2 of the datasheet.

I'd be happy to put together an example and modify the library to support touch and hold configuration - but it may have to wait a while!

Thank you for your fast response.
In the specs, there is mention of a ALERT pin.
So, for 'Touch and Hold', do we need to use Interrupt?

Very much appreciate if you update the library and samples. Many thanks!!

Yep, I'd believe you need to use interrupt.

Hi Chris

Here is what I am doing but I am not getting the ALERT interrupt:
Here are the config:
Register 0x2A value: 0x00 // CAP1298_MTCONFIG
Register 0x1F value: 0x5F // CAP1298_SENSITIVITY
Register 0x28 value: 0xFE // CAP1298_RPTRATEENABLE
Register 0x26 value: 0xFF // CAP1298_CALIBRATE
Register 0x23 value: 0x0F // CAP1298_SENSINPUTCONFIG2
Register 0x27 value: 0xFF // CAP1298_INTENABLE

Q1: Why am I not getting any interrupt?

Q2: If I receive the interrupt, do I check the status at 0x03 (CAP1298_SENSTATUS) ?

Hi LiveRock,

Unfortunately my CAP1298 is no longer responding, so I won't be able to further troubleshoot or adapt the existing code.

With regards to your questions:
Q1: I couldn't say without seeing your setup and code.
Q2: I haven't implemented any touch and hold/interrupt features, and cannot test, so I can only guess from reading the datasheet. Is the INT bit in 0x00 changing state at all?

Thank you Chris. Let me spend a bit of time to figure it out.
