Hi All,
Need help in ADE 7754 accuracy and calibration issue.
I am using MSP430F5438 as MCU and ADE 7754 as ADC for three phase measurement. Communication and init were done. But the accuracy was very less in lower Amps like 1 or 0.5 A. So decided to calibrate the ADE 7754.
Hence connected the ADE through parallel port and accessed with ADE7754 Evaluation software. While reading LAENERGY register the software waits for IRQ signal. So tried the same with SPI shortcut without IRQ signal and read the LAENERGY register value but the value was very random and high.
Plssssss help me on the same ASAP.
Regards
Sundar
