Hi,
Can anyone possibly tell me how to check if my AD7887 is working or not?
I'm using an AD7887 (Vdd +5V) to read a 2 axis accelerometer. I'm following the datasheet, ma I can't read valid data.This is what I'm doing:
1) CS to low
2) delay 5us
3) on first clock cycle I give an HIGH state on DIN pin (DONTC…
Hi, I am trying to interface AD7887 with Atmega32, and I am stuck with how to read Spi for continuous 16 clock cycles. Also, I came across this code for AD7887_Read16Bits(), where one needs to pass 2 control bytes. What are these control bytes?
Now I set all unused pins to "-1". When kernel start I see this message:
...
setting trigger mode 2 for irq 54 failed
ad7887: probe of spi1.0 failed with error -22
To date I see "ad7887" in the"/sys/bus/spi/drivers/", and don't see…
可以参考一下AD7888的示例代码，AD7888与AD7887结构类似

I am using the AD7887 in an electrically noisy environment. I want to filter the chip select and clock signals. What range of rise and fall times can these inputs tolerate? Also, is there any hysteresis on these inputs. The timing specifications table…
We currently do not have a IIO driver for the AD7321. But there is a driver for the AD7887 which has a similar interface, the main difference is the placement of the bits in configuration register. You should be able to adopt it to work with the…
I created a driver for the ad7888 a while ago, unfortunately never had the chance to properly test it, but I think it should work. I've pushed the driver to the iio-ad7888 branch on the ADI linux repository. You can find the patch that adds support…
