I’ve read some previous posts here but none seem to address the particular setup I already have, so I’ll tell you what I have and perhaps someone can let me know if there is a way to do this, or if I need to use a different setup.
I have a RedBoard with a Qwicc port. Connected to that in series area two Qwicc Scale boards. Each board has a single TAS501 load cell connected to it. I also have a SerLCD (qwicc) as the last thing in the daisy chain.
Everything seems to work, except that I cannot see how to address each qwicc scale board independently. Using the sample programs, it is reading both qwicc scales simultaneously.
Do I need a board with separate serial busses, or two separate RedBoards, or is there a software / firmware way around this?
My intent is to display the independent values simultaneously on the LCD screen, as well as a calculated grand total in real time on the second line.
The NAU7802 on the Qwiic scale only has one fixed address, so you can only have one directly on a Quiic bus. If you need more than one, you can either use multiple I2C busses (if your processor supports that) or a Qwiic mux like https://www.sparkfun.com/products/16784
Thanks for turning me on to that device, that looks like exactly what I need. I downloaded the library and looked at the sample code for using two laser distance measuring devices, that looks to be similar to what I need to do. I’ll probably need more coding help going forward as I am new to the Arduino programming language and environment. I have some experience with PHP (getting rusty) so the syntax looks somewhat familiar but there’s a lot of device addressing that is a bit involved. I’ll get the mux unit on order and start poking around and come back with questions later.
Edit: It’s backordered! Hopefully for not too long…
