ade7754 interfacing

Hi Alls,

Can anybody send me read routine that is...how to performe read operation from ADE7754 with megga88 microcontroller using SPI lines......send me what ever the related code......that use SPI lines in AVR series.

hi
Did u start working on your project?
have you calibrated the ADE7754?
its not only you have to perform the read operations from the microcontroller...but calibration should me done thru the microcontroller as the end product may or maynot have PC.
reading the registers from ADE involves the interrupts..u need to check interrupt
before you read the data from the registers.
if you have done some work on this i can help you....

reading data from ade7754

We brought ADE7754 Evaluation board.
The supplier gave us ADE7754Evalr3pa and ADE7754Cal software, of which 1st one runs
smoothly but second one fails to recognize the
board software.
What is wrong any idea?

reading data from ade7754 spi

both are differnt softwares they have to be used for differnt purpose.
calibration software is to calibrate the meter just check out the procedure to calibrate the meter. the doument comes with the CD.

avr ade7754

unsigned char spi_read()
{
#asm("nop");
SPDR=0x00; // data register
while(SPSR.7==0); // wait up to read cycle to complete
return SPDR;
}

use this if u had inbuilt SPI lines
