- 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 with a controller board.
- Power the BMS carrier board with 12 V.
- Set the CS pin of the BMS carrier board low, set the MOSI MISO pin of current sense low, set the MOSI MISO pin of current sense high, set the CS pin high. The same signals should be 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 MISO signals.
- Turn the power supply off.
