Overview
|
|
========
|
|
The TEMPMON project is a simple demonstration program of the SDK TEMPMON driver.The
|
|
temperatue monitor (TEMPMON) module features alarm functions that can raise independent
|
|
interrupt signals if the temperature is above two high-temperature thresholds and below
|
|
a low temperature threshold, the system can then use this module to monitor the on-die
|
|
temperature and take appropriate actions such as throttling back the core frequency when
|
|
a the high temperature interrupt is set.
|
|
|
|
Toolchain supported
|
|
===================
|
|
- IAR embedded Workbench 9.30.1
|
|
- Keil MDK 5.37
|
|
- GCC ARM Embedded 10.3.1
|
|
- MCUXpresso 11.6.0
|
|
|
|
Board settings
|
|
==============
|
|
|
|
Prepare the Demo
|
|
================
|
|
1. Connect a USB cable between the PC host and the OpenSDA USB port on the board.
|
|
2. Open a serial terminal with these settings:
|
|
- 115200 baud rate
|
|
- 8 data bits
|
|
- No parity
|
|
- One stop bit
|
|
- No flow control
|
|
3. Download the program to the target board.
|
|
4. Either press the reset button on your board or launch the debugger in your IDE to begin running the example.
|
|
|
|
Running the demo
|
|
================
|
|
When the example runs successfully, the following message is displayed in the terminal:
|
|
~~~~~~~~~~~~~~~~~~~~~~~~
|
|
TEMPMON driver example.
|
|
The chip initial temperature is 40.8 ℃.
|
|
The chip temperature has reached high temperature that is 42.7 ℃.
|
|
The chip throttling back core frequency to waiting a desired cool down temperature .
|
|
The chip core frequency is 62500000 Hz.
|
|
The chip temperature has reached low temperature that is 39.5 ℃.
|
|
The chip will return to the normal process .
|
|
The chip core frequency is 500000000 Hz.

Note:
|
|
To debug in qspiflash, following steps are needed:
|
|
1. Select the flash target and compile.
|
|
2. Set the SW8: 1 off 2 off 3 on 4 off, then power on the board and connect USB cable to J23.
|
|
3. Start debugging in IDE.
|
|
- Keil: Click "Download (F8)" to program the image to qspiflash first then clicking "Start/Stop Debug Session (Ctrl+F5)" to start debugging.
