Hi All,
I'm have a question on AD7991.
How should we interpret the data? Is it big endian? little endian? or something other format?
Understand that 3 bytes is rather uncommon format.
Can anyone give me some advise on this?

For AD7991, Vref can use 5V?
With Vref=5V, can i supply Vdd= 5V and how about the I2C signal?
您好,我在使用ad7991时遇到一些问题
Hi Daryl, thank you for your response. I could make it works now. The problem I had using fast speed wasn’t the code, it was the pull up resistor I used in SDA signal and because of that, I had a delay in the rissing edge of SDA. That delay doesn’t affect…
Hi,
I am using the ad7991 adc with the Raspberry Pi2.
Reading single values from the \iio:device0\in_voltage0_raw works fine, but when trying to stream the data with osc, I am getting errors "Error while reading data: Resource temporarily unavailable…
这个芯片在使用时,有一些配置寄存器,用于配置芯片的工作方式。这个寄存器,配置完断电后,还需要再次配置吗?
这个芯片有两个型号—0和—1,配置时,地址不一样。在芯片上没看有标识,怎么判断是哪个型号的?
Hi,
I am a pretty newbie to developing linux embedded systems and working on the Jetson nano 2gb dev kit, which is Ubuntu 18.04.
What I want to do is to use an i2c device(ad7991) to read analog feedback and control two motors.
So far what I have…
有 AD7991的示例代码,AD7991 与 AD7992 功能类似,可以参考一下
