HI,

 

  Iam working on BF526 EZkit with LCD Ezkit extender, I searched for AD7147 driver in uClinux, but I dint found the one, driver is not ther in SVN trunk also, so Iam planning to take AD7142 as the refrence driver and to bring up AD7147 drver, but in AD7142 driver we have code only for push button part, not for  scroll wheel part, we need scrool wheel part also in the driver for our project purpose, So do we have any scroll wheel refernce driver in linux or in VDSP to continue my work.

 

Thanks and Regards

 

Deepthi

Deepthi:

 

I think someone has a driver close to done - it is just not yet committed.

 

When do you need it?

Yes. AD7142 driver didn't support non-button event yet. And AD7147 is still under-developping.

 

For how to process non-button events, you can take

 

AN-925 Sensors for the AD7147 and AD7148 CapTouch Controllers

as refrence.

deepthi,

 

I have checked in the new ad7147 driver into trunk head of blackfin uclinux kernel project. The driver supports both button and non-button events. You can take it as a refrence.
