I’m trying to read an impedance value with ADPD4000 connected to stm32L4, but I have two problems with the reading of the fifo buffer and the execution of the code.

• About the fifo, I don’t why it does not fill or it fills up with no sense value…

Good afternoon,

I need information about the Firmware or source code of this product?? Can any one help me with that.

Regards,

Is "multibyte burst read" available on the I2C interface on the ADPD4001?

   - To read FIFO_DATA (ADDR 0x002F).

   - I wants to read FIFO_DATA 75 bytes (3 bytes X 25 data) using a "multibyte burst read."

"Internally Generated ADC Voltage Reference. Buffer this pin with a 1 μF capacitor to AGND." in datasheet.

Capacitor value is fixed or need tuning by user?

I want using GPIO0 as interrupt X.

So I controlled registers as below. Is this the right control?

   - ADDR 0x0006(FIFO_TH) => FIFO_TH[7:0] = FIFO bytes size – 1

   - ADDR 0x0014(INT_ENABLE_XD) => INTX_EN_FIFO_TH = 0x1 (enable)

   - ADDR 0x0023…

We are working on a real-time wearable PPG solution. We understand that either ADPD4001 or ADPD1081 can be used.

Q1) I am wondering if you could comment on the accuracy and power consumption of those two ICs. Which one is recommended by you for a wearable…

你最关注的领域是什么？ADC/DAC？Power？RF？.....
