Three LEDs on the SCB board are used to indicate status:
- LED D5 is a green LED that is ON whenever the USB is connected to the SCB, which also powers the SCB and any connected TMAG3001 devices.
- LED D4 is a red LED that indicates the status of the INT pin of the connected TMAG3001 device. The SCB firmware polls the state of the TMAG3001 INT pin and turns on LED D4 when the TMAG3001 INT pin is asserted low.
- Note: This feature is only enabled when Collect Data has been pressed in the Rotate & Push tab inside the Results Data page.
- LED D1 is a green LED that indicates that the TMAG3001 EVM firmware is loaded on the board and the EVM is not in DFU mode. If the EVM enters DFU mode, whether through software or hardware, this LED is turned off while LED D5 remains on.
