TMAG5273: Interrupt on Sleep and Wake Mode

TI-CSC

Part Number: TMAG5273

Hello E2E Experts,

Good day.

I can't make it work in sleep and wake mode to give me an interrupt when the sensor makes a new measure. Attached I send the sensor's configuration just before I write the DEVICE_CONFIG2 with the value of 0x13. Have in mind that I read the configuration from the sensor.

One more. When I give the command for Wake up and sleep (DEVICE_CONFIG_2 = 0x03) the device first sleeps or first measures? If first measures then there is no point to use this mode in order to save power.
Workflow
1. Put the sensor into Wake up and sleep
2. Device measure and exit mode since INT_CONFIG_1 = 0xA4
3. Read angle value
3 Put the sensor again in Wake up and sleep mode

This leads to a continuous mode.

Correct me if I am wrong

Thank you in advance for your support.

Regards,

CSC

Hi CSC,

Thank you for posting to the sensing forum.

Once the device enters W&S mode, the device will go to sleep and wake up periodically to take a reading based on what you have set the SLEEPTIME field in SENSOR_CONFIG_1 to.

What do you have the SLEEPTIME field in SENSOR_CONFIG_1 set to? It could be that you have the device waking up very frequently, thus giving the appearance on being in a continuous mode.

Best,

Hello Alicia,

Good day.

Below is the configuration file for your review.

Let us know your thoughts.

Hi CSC,

If RSLT_INT is set to 1, the device is only able to output interrupts on the SCL pin, and not the INT pin of the device. This can be accomplished by writing 0xAC to the INT_CONFIG_1 instead of 0xA4.
