Hi Qin,

Unfortunately we do not have any Linux drivers for PCMD3140 at the moment. You could start with TLV320ADC5140 Linux drivers, which has a very similar register map.

Best,

Zak

HI ZAK

Hi Qin,

We don't have a linux driver for 4-channel PDM yet, but given the register map similarity between TLV320ADC5140 (PCMD3180) and TLV320ADC5120 (PCMD3140) families, the ADC5140 linux driver would still be a decent starting point.

Best,

Zak
