Hi Liu, The Clock that I get on the FSR PIN is 2MHz and on Sync pin is 6.5KHz.
But there is no interrupt generated. Please let me know if Any extra settings are required for or the readings are incorrect. Thanks, Azam. 2009/3/5 Liu Yebo <[email protected]> > HI, > The clock(For Ex: 8KHZ) is present on FSR PIN not CLKR PIN of DM355. > > ----- Original Message ----- > *From:* Azam Ansari <[email protected]> > *To:* Liu Yebo <[email protected]> > *Cc:* [email protected] > *Sent:* Wednesday, March 04, 2009 5:15 PM > *Subject:* Re: DM355 daughter sound card problem > > Hi Liu, > > I am making driver for TechWell TW2835 chip.
