ARM7TDMI - Obtain ARM Core Temperature

Pheonix Ashes
Note: This was originally posted on 9th June 2011 at http://forums.arm.com

Hi All,

I want to measure the temperature of LPC2129 ARM processor core.
The LPC2129 manual doesnt show if there is a temperature sensor in the ARM core.
Is there any other way to obtain the temperature using some tools or code?
Is is possible to code in some RTOS to get the temperature details?


Thanks & Regards,

    I don't know about what is in the lm_sensors software package, but it seems to ise i2C rather than SPI.
    So you will need software to control the I2C interface of your microcontroller, as well as code to wotk with the temperature sensor.
    You might be able to port the lm_sensors code across, but still need to have the suitable I2C interface control code to work with it.

    regards,
