I have connected a shunt resistor in series with my load and I connected the two wires to IAP and IAN through 1k resistors. The connection is given below. I used the AN-1118 as reference. Now I am facing a problem regarding the current value. I selected the current channel A gain as 16. Then I passed 10A through the shunt and calculated the multiplier factor by dividing the current value (10A) by the register value IRMSA. But when I change the current, the register value doesn't change and the LCD keeps on displaying the same current value. Is there any software calibration required for using shunt?
Thanks in advance
