Hello,
I'm trying to translate what the engineer has just experienced.
He tried to let ADC081S101 and raspberry pi 3 communicate with each other but failed. What should the communication protocol in this? Or How can have them communicate with each other
Hello,
This device communicates through SPI, it only uses 3 digital lines to communicate.
The CS, SDATA, and SCLK pins are needed to successfully communicate with the device.
A falling edge on CS begins the conversion, SDATA is the digital output, here you will see the conversion result.
Each bit of the output will be clocked out by SCLK.
I would suggest looking at page 6 of the datasheet, as the timing requirements of the device are outlines here, the most common issue with communication is timing errors. one way to debug this is visually, using scope shots of the digital lines to confirm what you are expecting is in fact what is happenning.
