I posted recently about getting set up with the demo for the GUI application, and got great help from @SRomeo. I've now moved on to the SingleAccess Chain demo, and could use some more help if you don't mind?
I am using the C4ML1T, ISOSPI1, and 2 BMS63EN boards each connected to a BMSHOLD cell holder. The first device has 8 cells connected to it, the second has 4. In both cases, there are cells occupying slots 1, 2, 13, and 14.
In AutoDevKitStudio, the AEK-POW-BMS63ENCHAIN component is set up with a single chain, with two devices. I have connected the ISOSPI1 board to the C4ML1T as per the allocated pins visible on the board view, below.
Once the code is compiled and generated, and the board is flashed, I get periodic LED illumination, and zero values for all data printed to the serial terminal. See video below for hardware behaviour, including how the frequency of the LEDs changes with a reset.
I suppose my first question is am I interpreting the board view pin designations correctly? NSLAVE isn't mentioned, and so I have left it disconnected (assuming there's internal pull-down resistors or something), and BNE/TxAmp are shown with an "X" which I have also taken to mean leave disconnected.
My ultimate goal with this is to be able to output voltage values for all cells across all devices to a terminal. Toward this aim, I have included a for-loop in the AEK_POW_BMS63CHAIN_app_serialStep function to iterate over devices as well as cells, as below. I will only ever have a single chain and so I don't need to iterate over that.
