I am trying to measure the current supplied to a standard LED. I have the INA219 wired properly and I am getting results that seem to be working properly. However, I want to increase my resolution. As it is an LED, and I am controlling the voltage and amperage, it's never going to be anywhere near the 32 AMP limit. So, in the product lit it says the board is capable of this:
With the internal gain set at the minimum of div8, the max current is ±400mA and the resolution is 0.1mA.
This sounds much better than the 0.8mA jumps I am getting now. However, when I looked at the library, it seems like I can get much better resolution... but I am not an electrical engineer or a mathematician. I don't have the faintest idea what I need to do to achieve the best resolution for measuring the current going to my LED.
