Hi Team,
I am trying to communicate with my bms using raspberry pi.
I am using 8 cells in series connected to AEK-POW-BMSCCTX from C0 to C8 (from cell taps-P1 connecter). From the P4 side VIO-3V, Vdd- 5v, GND. I have also connected the MISO,MOSI,CS and CLK of the pi with corresponding pins in bms. Also TXEN-high, DIS-low, BNE-low.
Using this run a sample Spi code and there is no correct reply. I just need to know is this connections correct? any extra connections do i have to do?
Also after connections, D9,D8 and D2 leds of my bms is light up. When spi is activated D7 led should blink but not in my setup. I hope i get this problem solved
Thank You.
