TSW1400EVM: Cannot read from ADC3221EVM, if configure to use one-wire mode.

Yuan Dao

Part Number: TSW1400EVM

Default ADC3221EVM setting works with TSW1400, however, when I change ADC3221 to use 1-wire mode, this "frame clock error" pops up.

Is only default setting supported by TSW1400?

Hi Yuan,

I set this up in the lab and saw the same error. I am checking with our design team and I will get back to you soon.

Hi Yuan,

To provide you an update, we are still checking into this. We are suspecting it is an issue with the firmware, so we are checking into that.

I will provide you an update either tomorrow or early next week. Thank you for your patience.

Hi Yuan,

Please try the following .ini file. I tested it out and I saw a good capture in 1w mode.

Additionally, ensure that you set register 0x05 to 0x01 to configure the part in 1w mode.
