Re: AD8347 Vcom Pin.
Hi, Youhei, The VCMO input sets the output common-mode level for the baseband outputs, as described in Table 3 on p. 6 of the AD8347 datasheet. The input range when operating under 5V supply is...

Hi, What exactly do you mean by execution stops? iio_device_create_buffer() never returns? Is it possible that you accidentally disconnected some of the signals in the design, e.g interrupts or clocks?...
View ArticleRe: AD7414 - Seemingly Inaccurate Temperature Readings
Hi, I'm not sure I followed 100% your code, but basically when reading negative temperatures you need to take the 10-bit word, eliminate DB9, and then substract 512 (200h) and divide by 4. Are you...

Re: ADXL362 REGISTER DETAILS
Hi Honkawad, Eg: if you want to make the part work @ 2g, 100Hz ODR, enable SELF_TEST, you need to write FILTER_CTL and SELF_TEST registers. If the part is in measurement mode already, after writing...
