Hi everyone,
I'm trying to use the TEMPMON peripheral on my NXP microcontroller and could use some help. I'm not sure if TEMPMON is the internal sensor of the microcontroller. Can anyone explain how to set it up and read the temperature? Is there a sample code? I am writing in C and bare metal.
The nxp document link is now obsolete. I could not find the example codes.
https://www.nxp.com/docs/en/application-note/AN5215.pdf
I'm looking for:
- How to initialize TEMPMON.
- How to start a temperature measurement.
- How to read the temperature value.
A simple code example would be awesome!
Thanks!
The registers I found in the documentation file is :
#define TEMPMON_TEMPSENSE0_POWER_DOWN_MASK (0x1U)
#define TEMPMON_TEMPSENSE0_POWER_DOWN_SHIFT (0U)
#define TEMPMON_TEMPSENSE0_POWER_DOWN(x) (((uint32_t)(((uint32_t)(x)) << TEMPMON_TEMPSENSE0_POWER_DOWN_SHIFT)) & TEMPMON_TEMPSENSE0_POWER_DOWN_MASK)
#define TEMPMON_TEMPSENSE0_MEASURE_TEMP_MASK (0x2U)
#define TEMPMON_TEMPSENSE0_MEASURE_TEMP_SHIFT (1U)
#define TEMPMON_TEMPSENSE0_MEASURE_TEMP(x) (((uint32_t)(((uint32_t)(x)) << TEMPMON_TEMPSENSE0_MEASURE_TEMP_SHIFT)) & TEMPMON_TEMPSENSE0_MEASURE_TEMP_MASK)
#define TEMPMON_TEMPSENSE0_FINISHED_MASK (0x4U)
#define TEMPMON_TEMPSENSE0_FINISHED_SHIFT (2U)
#define TEMPMON_TEMPSENSE0_FINISHED(x) (((uint32_t)(((uint32_t)(x)) << TEMPMON_TEMPSENSE0_FINISHED_SHIFT)) & TEMPMON_TEMPSENSE0_FINISHED_MASK)
#define TEMPMON_TEMPSENSE0_TEMP_CNT_MASK (0xFFF00U)
#define TEMPMON_TEMPSENSE0_TEMP_CNT_SHIFT (8U)
#define TEMPMON_TEMPSENSE0_TEMP_CNT(x) (((uint32_t)(((uint32_t)(x)) << TEMPMON_TEMPSENSE0_TEMP_CNT_SHIFT)) & TEMPMON_TEMPSENSE0_TEMP_CNT_MASK)
#define TEMPMON_TEMPSENSE0_ALARM_VALUE_MASK (0xFFF00000U)
#define TEMPMON_TEMPSENSE0_ALARM_VALUE_SHIFT (20U)
#define TEMPMON_TEMPSENSE0_ALARM_VALUE(x) (((uint32_t)(((uint32_t)(x)) << TEMPMON_TEMPSENSE0_ALARM_VALUE_SHIFT)) & TEMPMON_TEMPSENSE0_ALARM_VALUE_MASK)
