Hi Bill, I made a small mistake in the default IIC address 🙁. I fixed that.
Some other remarks. I saw in a video that the Arduino Library you mentioned is not correct. I saw in your update that you corrected that. I saw the same fix in an Arduino Library from Adafruit. I also saw you added a function to read the register values which is handy. I added the changes to the attached library but I also added a timeout function. When the IIC communication is not working this function will return TRUE after you called it (after which it will be reset). I changed the call to the IIC routines so that it keep track of any timeout. I updated the samle program. Next to that I changed the array with shunt resistor values by floats and set them by defaul to 0.1 Ohm which seems to be the commonly used value and I saw that was also the case in your update. I think I will extend the library further and I am thinking of ordering a module to test. The library needs functions to change for example the shunt resistor value, etc. So see if you still get non-changing values and check the timeout and if so, change the IIC address.

The current shows 1.6447997E1 with and without current. The voltage shows 8.223999E0 with and without voltage. So, nothing changes. I looked at the datasheet and the library and made some adjustments, also without success. I also tried reading the config, ID, and manufacturer registers, all of which returned 4040h. But I’m not sure if I dit that right. Here is my version with a litle typo.

I only implemented the functions you called. I might add more functions later. You find the libary and a sample program for a PIC16F1825 so you may need to swich to a PIC that you normally use. I only compiled it since I could not test it. Can you give it a try. Thanks.

I'll try again. Hi Rob, thank you for your quick response. Currently I have 1 INA3221 board left so I can still test. I now use the library of Rob Tillaart "INA3221_RT" #include "INA3221.h" INA3221 INA(0x40); And the commands for initialization and default setup. INA.begin(); ch = 0 to 2 U = INA.getBusVoltage(ch); I = INA.getCurrent_mA(ch); I hope this is enough info, Thank you very much for the effort. kind regards, Bill.

I do not have such a device so I cannot test it so if I have something you become the tester 🙂. Can you tell me which Arduino functions you use from this library?

By the way, I only use the Volt and Amp functions. So far I use an Arduino Nano and the INA3221 in a triple output power supply . But I like JAL much more.

I had a quick look at the Arduino library and it seems to be a number of small but readable functions and 'only' about 500 lines of source code so it seems douable to make a JAL library out of it. How far did you get porting it?

I've been looking at the arduino lib to convert it to a JAL lib, but it's a bit too complicated for me.
