To connect the AMO ASMOP1BO0N21 UWB SR150 Module to a host device, you will need to use the SPI interface. The SPI interface supports synchronous, serial, full-duplex communication between the module and the host device. Here are the steps to connect the module to the host device:
1. Identify the SPI pins on the module: The SPI pins on the module are labeled as Host_1, Host_2, Host_3, and Host_4.
2. Connect the SPI pins to the corresponding pins on the host device: Make the following connections between the module and the host device:
- Connect the Host_1 pin on the module to the SCK (Serial input Clock) pin on the host device.
- Connect the Host_2 pin on the module to the NSS (Not Slave Select) pin on the host device.
- Connect the Host_3 pin on the module to the MOSI (Master Out Slave In) pin on the host device.
- Connect the Host_4 pin on the module to the MISO (Master In Slave Out) pin on the host device.
3. Connect the other necessary pins: In addition to the SPI pins, you may also need to connect other pins depending on your application. For example, you may need to connect the GPIO05_SENSORINT pin for IRQ communication between the module and the host device, or the CHIP_EN pin for enabling or disabling the chip.
4. Configure the SPI interface: During production, the SPI-bus interface settings are programmed into the module. The SPI-bus IP supports four operating modes, which can be selected using the SPInCfg register. Refer to Table 5 in the user guide for the different operating modes and their configurations.
5. Ensure proper power supply: The module requires a supply voltage (VDD) between 1.71V and 1.98V. Make sure to provide the appropriate power supply to the module.
By following these steps and referring to the module's user guide for more detailed information, you should be able to successfully connect the AMO ASMOP1BO0N21 UWB SR150 Module to your host device using the SPI interface.
