I am stuck with my project. I have to measure the frequency characteristics of an unknown impedance valued sensor.
How to do that ?
How to interface Arduino Uno board with Evaluation board EVAL AD5933EBZ ?
I cannot see any connections on the EVAL AD5933EBZ to be interfaced with other devices.
How to interface other devices with EVAL…
Apologies for the delay. I have overlooked your follow-up question.
The board should always be calibrated for a change in any of the following parameters:
The documentation is indeed confusing, it is stemming apparently from the differences between the AD5933 datasheet and the evaluation board documentation, where the bits and pieces of the text and schematics…
Do you have the AD5933 evaluation board (EVAL-AD5933EBZ) with you?
The AD5933 evaluation board is a test system designed to simplify the evaluation of the AD5933.
Or are you going to design your own custom board?
Yes, I have EVAL-AD5933EBZ board with me.
Is EVAL-AD5933EBZ and AD5933 both are different ?
I cannot interface AD5933 chip with other devices using EVAL-AD5933EBZ board.
What do you mean by custom board ?
EVAL-AD5933EBZ is the evaluation board of AD5933, while AD5933 is the chip itself.
You can interface other external devices to the EVAL-AD5933EBZ board using the available test points/nodes at the board. What other device(s) are you thinking of using together with AD5933?
A custom board is your own designed board.
For your question on test points for the serial programming (I2C) using Arduino board, that is right, there are no available test points. I think this has been responded on this thread: About SDA and SCL pins on AD5933 to interface with other hardware
As you requested, here are snapshots for your reference where to tap for SCL and SDA lines:
You can tap at R15 and R16 for the 2 lines.
How to interface other devices with EVAL AD5933EBZ is my main question. Can you please explain that with the help of Pictures ?
