I'm trying to understand more about Ade 7953. I'm reading normally and without problem voltages and active power ( I'm using a load of 7.5 Kw, 220V for test).
I simply don't understand how to measure current consumption over time, so basically I would need to understand how accumulation work.
Can you please me advice on how to approach this ?
In order for you to do accumulation of energies, you should perform the following checklist:
1. Make sure you have your real value conversion fro codes to Watthr (or any parameter). This can be calculated based on your sensors selection and the headroom and the full scale codes of the ADE9153A., use the Datasheet for your guide.
2. Make sure you calibrate your meter.
3. In order to do the energy accumulation, configure the important registers, especially the ACCMODE regiter. Use the accumulation registers like xENERGYA register in measuring the value.
hi , thanks for your answer. one simple question ( I'm really newbie ) on how to write to register.
As per my understanding I would need ex. to put value -9.6593 in a register ( ex 0x388) for offsets settings.
As it is 32bit I would need to write 4 time 8 bit as per SPI spec. then how do I convert this number to the 4 8bit values?
EX: -9.6953 = =0xff 0xf1 0xc2 0x22 ( totally wrong number but to show example). could u advice me ?
