Re: help with ade7753
Hi,
Thanks.
I am trying to read IRMS and VRMS registers. I am getting large hex values. datasheet says that it should be converted into amps/LSB constant. But I don't have any idea how to do that. I have gone through the calibrating pdf. Please help me.
ade7753 & waveform
Hi,
Thanks for explaining me.
AENERGY register is signed by two's complement method. How should I read the value from register? If I am reading using unsigned variable, how to convert it so that I can get the right value.
ade7753 irms register
Hi,
In table 6 of datasheet on page 16 it is said that LSB size is 1.61mV/LSB. What does this exactly mean? and somewhere it is also said that 2.2ms/LSB. what does this mean?
Thanks.
ade7753 atmega32 source
hi,
Thanks for all your help. Its working.
I don't have current transformer and voltage transformer. Do you have any idea how can I test whether whole circuit is working or not.
Thanks in advance.
ade7753 code for spi atmega32
Hi,
Thanks. Its working now.
One more doubt is that some of the registers in ade7753 are signed and some are unsigned.
My functions are declared as unsigned.
Can you please tell me how to handle signed numbers.
Thanks.
calibrating the ade7753
Thanks very much.
I thought every thing is fine. That simple statement mistake was not noticable.Now I will correct it and run the program when go to lab and let u know.
And you said that address should not have +0x80.
The reason to add 0x80 is that in command...
ade7753 vrms calculation
Thanks for your reply.
Actually I am using sck as f/16. I forgot to change the comments there.
If every thing is fine, I don't know where am I going wrong.
Can you please tell me if not in the code where I am going wrong probably.
Hi,
Thankyou very much.
Please if you don't mind, I had posted another doubt in the Microcontrollers forum under the topic "help with ade7753",here is the link
#1053020
My spi communication module is not working. Can you please check that and correct me.
Thanks in advance.
Hi,
I am doing a project using ade7753 and atmega32.
I am not able to establish communication between two.
Can someone please help me.
This is spi code.
int main(void)
{
// initialize our libraries
// initialize the UART (serial port)
uartInit();
// set the baud rate of the UART for our...
Hi,
Thanks for helping me.
Thats not my projblem. Once I receive two or three bytes after transmitting dummy values, how can I append them to get one value which is needed.
Thank You.
manipuler 24 bits spi
Hi,
I am communicating atmega32 with ade7753 through spi. atmega32 as master and ade7753 as slave. I need to read 16/24 bit registers from ade7753. But only 8 bits are transmitted once.
How should I read 16/24 bits through spi.
Please someone help me regarding this...
