INA219 module and ...

I was looking for something that could read current and voltage, and came across this module. Wondering if anybody has used this with, maybe a Propeller, using C code.

It seems like there is example code and a wiring diagram for a Raspberry Pi, but I wonder if this could be workable with the new P2, and of course the P1.

Thanks

Ray

    It should work with P1 and P2. I have used 3 of them with P1 to monitor a 3 output power supply, and am planning to use it with P2 when my P2D2 board arrives.

    I used that device in a commercial product (laser-tag controller). My code is, of course, Spin. That said, it's very simple and you should have no trouble converting it to C.

    Here is a thread about the device in BS-2 from a few years ago.

    I passed on this module and instead went with INA260 which seems to be better at measuring current and voltage.

    I used the one from Adafruit.

    Wrote C code to drive it nicely.

    iseries mentioned the INA260 module, which I think will be more useful for my purposes. Still have not decided how I will code the program. And, at a minimal I will probably need, to start with, at least four of theses modules, which brings up the question of, how do I make the modules available on the I2C buss.

    I also looked at Jon's jm_ina219.spin program, I wonder how that would work with the flexGUI IDE. The last time I used the spintoc part of flexGUI, to convert some Spin code to PropGCC, I was not able to make the PropGCC code work correctly.

    I will probably be collecting the INA260 data, continuously, and feeding it to an SQLite database, for further analysis. These are just a few things that I have in mind.

    Both device types have A0 and A1 (address) inputs which allow up to for devices on the bus.

    My object will work if you write your code in Spin or in FlexC.

    I've attached a demo program that uses four of my Spin objects without modification/conversion -- one that launches a PASM cog (serial io). Interesting, the C binary image was a little bigger than the identical program written in Spin; this may have to do with overhead dealing with Spin objects in C. Still it works, so I can write C code without walking away from all of my existing objects. Spin is my favorite Propeller language, but it's nice to have C as an option.

    yes, the multi-language feature of fastspin is a wonderful thing.

    https://forums.parallax.com/discussion/169141 has several examples of mixing FastSpin's languages and even one using FastSpin compiled cog PASM output in OpenWrt which turned out to be purely straight forward.
    What I don't see how to do so far: Including/using bytecode Spin in FastSpin LMM code and the other way round. But I dont expect much demand for this. :-)

    I put my INA260 driver in the OBEX if you are interested in a C version of the driver.

    Thanks Jon, for the excellent examples. I will look into the code to see how your Spin objects work within a C or flexBASIC confine.

    Thanks iseries, for a pointer to your libina260 driver. I will also take a closer look at your SimpleIDE implementation for using the INA260.

    Now, I have to get a better understanding of the code that has been presented so far before I make a decision as to what I will be using. Will it be SimpleIDE, flexC, flexBASIC, micropython, or, …

    Another choice P2 Eval or FLiP module or ...
