Hi Charles, Thank you for your query. I won't be able to help you with Raspberry Pi and Qt. However, I am putting down the generic setting in any SPI driver, You can configure this and get started with some example code: 1. SPI Mode: 01 2. CS Polarity: ACTIVE LOW 3. Speed: Any allowed value less than 30MHz 4. Word/packet size: 16 bits 5. CS type: Per Packet Noe that this is an exhaustive list. Many drivers may not have exposed all of them. So, just configure the necessary ones and send the data as mentioned in the datasheet of the DAC. Hope that answers your question. Regards, Uttam Sahu Applications Engineer, Precision DACs
