- Connect the current sense board to a validated BMS carrier board.
- Connect a logic analyzer to the SPI testpoints and ISO GND of the current sense board.
- Power the BMS carrier board with 12 V.
- Set the CS pin of the BMS carrier board low, set the MOSI pin low, set the MOSI pin high, set the CS pin high. The same signals should be seen measured by the logic analyzer.
- Repeat the process above, but instead of switching MOSI, set MISO low, then high. The BMS carrier should receive the same signals.
- Turn the power supply off.
