I use a CY3280MBR3 to rate the CY8CMBR3116,
I use an arduino as a host.
my sketch is very simple, for every touch detected I send MIDI notes
I have a very bad times responses: 78 - 80 ms.
If a try my timing test before I2C communication, I have 77 ms between the trig sensor and the interrupt pin signal.
In the software the initial response times says 80 ms and the subsequent response time 60 ms.
there is a way to have more fast responses, the datasheet say 20 ms scanning times; why the interrupt pin signal arrive 77ms after the trig ?
You can try to set the debounce to 1, when debounce =3, a sensor won't be triggered until it is detected for 3 consecutive scan cycles.
