FRDM-RW612: Hands On 3: ISP and Temperature Sensor

[#1]

This demo shows the temperature measured from the i2c temperature sensor integrated in the board. The information can be monitored in the UART terminal or in the IoT Toolbox app.

• Binary required for the lab: frdm_rw612_peripheral_ht_binary.zip

I'm seeing a fail with the temperature read using the supplied binary:

Both the SDK demo_apps/temperature_measurement and driver_examples/i2c/read_p3t1755_temp_value_transfer work correctly.

Hello,

Could you please let me know the Zephyr-SDK version. We know that connection maybe instable with Zephyr-SDK 0.16.8 

Could you please try with Zephyr-SDK 0.16.4, you can download from this link

https://github.com/zephyrproject-rtos/sdk-ng/releases/download/v0.16.4/zephyr-sdk-0.16.4_windows-x86...

Once it is download uncompress the file in same folder you have the other version by default is usually C:\users\*your_user*\ , This is to try that VS Code shows the new SDK automatically, but you can also import the SDK from the path you choose 

After the SDK is imported go to VSCode and do a right click on the project and select   Configure->Associate Zephyr SDK

A list will pop up in the top of the VSCode select the new SDK 0.16.4

now clean the project and compile again

Hope this helps

I was running the binary provided by the class, so I don't know where the source is.

I am able to build, run, and see the fake temps in IoT Toolbox for: https://github.com/zephyrproject-rtos/zephyr/tree/main/samples/bluetooth/peripheral_ht

 Where is the support for it to read the frdm_rw612 sensor in zephyr?
