TSS Settings

[东升王]

Hi

I implement a keypad (15 keys) that uses 8 electrodes (3 columns, 5 rows) in KL05 with KDS3.0. Now I have a problem. When I pressed one key, did not release it, then I pressed another key that in the same row or column, that means the two keys shared one electrode, the TSS library can not report the second key. How can I config the PE to implement this feature.

Thanks

Hi Dongsheng

you can check the TSS samples for the TWR board

C:\Freescale\Freescale_TSS_3_1\examples\TWRKXX_DEMO\build\cw10

please check the section for the keypad2,

I use the k60 and it can detect two number (like 4 and 1) that share one electrode touched at the same time.

Also you can use freemaster to check the delta variation on each electrode, with this variation you can detect the two diferent keys that share the same electrode

Have a great day,
Vicente
