HI team,
I want to measure the sensor controller power consumption, but I am experiencing the following issues :
Question 1: The sensor controller of CC1312 can be debugged with the software Sensor Controller Studio, how to permanently download the code into the 1312?
Question 2: How to test the power consumption of the sensor controller via an ammeter, how do I know?
Question 3:How to turn the peripheral on/off
Thanks & Best regards
Yolande
Hi Yolande,
1: Please refer to our SimpleLink Academy on that topic: https://dev.ti.com/tirex/nodeContent?node=A__AddniPdrlDWP1siaPICBSw__com.ti.SIMPLELINK_ACADEMY_CC13XX_CC26XX_SDK__AfkT0vQ__LATEST
2: You can use our EnergyTrace tool (https://www.ti.com/lit/an/swra478d/swra478d.pdf), and compare the results with the numbers from our datasheet, or the Sensor Controller Studio help page.
3: You can use the scifInit() and scifUnit methods from the scif framework present in the files generated by SensorController studio.

Hi Arthur,
Is there no configuration related to the Sensor Controller in SysConfig? For example, tdc, compa, compb, isrc, etc.
Thanks & Best regards

Hi Yolande,
Indeed, there is no such configuration in SysConfig.

Hi Arthur,
1.Call sleep() in the program to let the main CPU sleep, so that the power consumption mainly reflects the power consumption of the sensor controller, how to do this? How do I write to operate the SensorController on a bare metal, is there a tutorial?
How to make the main system sleep in the project?
3.ISRC, TDC The power consumption of this peripheral is where to look?
Thanks & Best regards
Yolande
Hi Yolande,
The tutorial is in the SimpleLink Academy link that I have linked previously.
Is there information missing?

Hi Arthur,
How to measure the sensor controller power consumption of the C1312 separately, can an ammeter be used?
Thanks & Best regards
Yolande
Hi Yolande,
You cannot measure the sensor controller power consumption separately.
What you can do is load your sensor controller firmware on top of the "empty" project from the SDK, disconnect the LEDs, and watch the power consumption using the EnergyTrace tool, for instance.
With the sensor controller active, you should see a current consumption of around 900 uA:
