Please share your code. It seems you did not initiate properly the object to match your device.

I use the example Demos from your Library.

sosandroid commented 5 years ago

Thanks for your help.

Obviously, the chip you used does not match to product IDs of the Cypress datasheet.

As consequence, the library is considering the chip not found. This is a normal behaviour.

You should try to switch to manual mode as the lib allows you to do so.

Sorry for that. Just try to address it in manual mode. Maybe fake but working

If same issue than #18 please try manual mode by setting density manually
