no matching function for call to 'ATM90E36::ATM90E36(int)'

Hi,
Nice Work. Appreciate it. Just wondering about how to fetch DFT and THD from this chip.
Thanks

Hello,

In SPI/ Normal mode (DMA -> Low / PM0,PM1 -> High), I am getting all 1's from all the registers.
I tried it with a couple of different ATM90E36A boards.
Please guide me, what may have gone wrong.

Thank You in Advance!

Here is the snap from Serial Monitor for a better understanding of the problem.

S0:0xffff
S1:0xffff
E0:0xffff
E1:0xffff
VA:655.35V
VB:655.35V
VC:655.35V
IA:65.54A
IB:65.54A
IC:65.54A
f655.35Hz

I'm using a CT 100A/50ma, but in the real world with my tests it doesn't exceed 65.5A.
Would you be able to help me?

Hii Dhar,

I am working on interfacing of ATM90E36 with ESP32. As per the your library, interfacing was successfully carried out. However, while reading the data (only three phase voltage and frequency), some of data getting missed and showed zero.

and its repeating as cycle but most of time we are able to get the value but only some time it is missing.
Could you help me out to rectify this issue?

Thanks in Advance!

Hi,
I am using ATM90E36A Development Kit with Nodemcu and tried your Code with following connections
D5-SCK
D6-MISO
D7-MOSI
D3-SS
(I didn't have adafruit board so tried with above connections on NodeMCU)

and the Output is something like

I am not able to trace these random value.

I also pulled high PM0,PM1, but results are same.

Is it because I didn't calibrated device?
Is there any video or document to calibrate device?

Hello Sir

I am currently working on a project of computing energy in a 3 phase system. For this, I am using ATM90E36 IC along with ESP32.

Your .ino code has been really helpful in computing most of the essential parameters and I'd like to thank you for sharing the code on Git.

However, I am facing an issue with 2 functions, eic.GetImportEnergy() and eic.GetExportEnergy(), for which the output is showing as 0(zero).

Can you please guide me why this is happening and what changes should I make in code to get real-time energy readings? I am attaching .ino file and screenshot of the output for your reference. I am only using one phase for time being to test my hardware and software.

Another thing, I have to multiply current by a factor of 6.83 to get the actual value. I came up with 6.83 factor by comparing it with a calibrated meter. So my 2nd query is whether there is a provision to compute the actual current without the need to tweak it by multiplying with 6.83?

I am using 120A-40mA Split Core Current Transformer to sense current. The hardware circuit that I've used on CT side is same as mentioned in the ATM90E36 Application note. I am attaching PDF of the circuit layout I've used for your reference.

I would really appreciate if you could help me solve the issues I am facing. Let me know if you need any more information from my end

atmel_current_application_note.pdf
arduino_code.txt

When calculation the HIGH WORD of the Checksums 0 - 3 only the last 7 digits are considered. It should be the last 8 digits!

E.g. in Sheet "Measurement Calibration" the formular in cell G39 should end with ... )));8)

Thanks for all your effort whatnick and igorgassv!

Hi,
I am trying to use YHDC SCT 013-100 CTs with ATM90E36 but having no succes caliberating it. The output is 50mA with turn ratio 2000:1. Previously I have used these clamp CTs and have caliberated them, these are working fine. I am using the same method as suggested by the datasheet. However, the value of register that I get upon my calculation increases way beyond 65000. What am I doing wrong?
Can anyone please help me with this?
Thanks.
