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