To connect the FRDMSTBI-NMH1000 shield board to a NXP Freedom MCU board for evaluation, follow these steps:
1. Make sure you have a FRDM-KE15Z MCU board, a PC, and the project demo software available from NXP.com.
2. Connect the FRDMSTBI-NMH1000 shield board to the FRDM-KE15Z MCU board using the Arduino headers. Ensure that the headers are properly aligned and securely connected.
3. Set the interface mode of the NMH1000 sensor by adjusting the jumpers on the FRDMSTBI-NMH1000 shield board. For I2C mode, set jumper J1 to position 1-2 and turn on jumpers J7 and J8. For standalone mode, set jumper J1 to position 2-3 and turn off jumpers J7 and J8.
4. Select the threshold and sample rate for the sensor in standalone mode by adjusting the jumpers J9 and J10 on the FRDMSTBI-NMH1000 shield board.
5. Connect the I2C interface between the FRDMSTBI-NMH1000 shield board and the FRDM-KE15Z MCU board. Use the SDA (Serial Data) and SCL (Serial Clock) pins on the J5 connector of the shield board.
6. Ensure that the VDD (power supply) and GND (ground) connections are properly made between the FRDMSTBI-NMH1000 shield board and the FRDM-KE15Z MCU board. These connections are typically supplied through the J6 connector on the shield board.
Once the hardware is properly configured and connected, you can proceed with the evaluation and software development using the FRDMSTBI-NMH1000 shield board and the NXP Freedom MCU board.
For more detailed information and illustrations, refer to Section 5 "Configuring the hardware" in the NXP UM11835 FRDMSTBI-NMH1000 Shield Board User Manual.
