temperature_measurement_1#
Overview#
The temperature measurement demo is used to measure the temperature within the tempsensor, note that this case just support i.mx95 platform at present.
Supported Boards#
IMX95LPD5EVK-19
Hardware requirements
Micro USB cable
IMX95LPD5-EVK board
J-Link Debug Probe
12V~20V power supply
Personal Computer
Board settings
No special settings are required.
Note
Cannot get temperature from sensor temp_a55. It’s an expected behaviour.
Prepare the Demo
Connect 12V~20V power supply and J-Link Debug Probe to the board, switch SW4 to power on the board.
Connect a micro USB cable between the host PC and the J31 USB port on the target board.
Open a serial terminal with the following settings:
115200 baud rate
8 data bits
No parity
One stop bit
No flow control
Download the program to the target board.
Either re-power up your board or launch the debugger in your IDE to begin running the example.
Running the demo
The log below shows the output of the hello world demo in the terminal window:
Temperature measurement example.
desc[0].sensorId = 0x0
desc[0].name = temp_ana
desc[1].sensorId = 0x1
desc[1].name = temp_a55
desc[2].sensorId = 0x2
desc[2].name = temp_pf09
Pls input a number to choose sensor to get data:(valid input is 0-2)0
Sensor(desc index is 0) temp_ana is selected
Sensor is ready to read, press enter key to get the temperature.
Current temperature is 39 degrees Celsius
Pls input a number to choose sensor to get data:(valid input is 0-2)1
Sensor(desc index is 1) temp_a55 is selected
Sensor configuration failed!
Pls input a number to choose sensor to get data:(valid input is 0-2)2
Sensor(desc index is 2) temp_pf09 is selected
Sensor is ready to read, press enter key to get the temperature.
Current temperature is 105 degrees Celsius
Pls input a number to choose sensor to get data:(valid input is 0-2)
