RAK3172/STM32WLE5 Pin Assignments/RUI Capabilities

[kefecik (K)]

Hello, I was looking through the STM32WLE5 datasheet. I have some questions about what can and cant be accessed through the RUI

1. There is an onboard Temperature sensor on ADC channel 12. Is there any way of accessing that through the RUI?

2. Theres also a DAC on PA10. I couldnt find any mentions of a DAC in the 3172 datasheet. Could I just set up PA10 as analog out through the RUI?

3. Id like to test the available pins on the 3172 but the breakout board for it has limited amount of pins. However the SiP version breakout board has all of the pins that are available on 3172 non SiP and more. If I write some code using the RUI for the SiP version, could I run the same code on Non-SiP version as long as I only use the available Pins?
   Thank you

RUI3 doesn’t have functions for the internal temperature sensor and the DAC output.
You can check in the uhal/udrv functions in the RAK3172 BSP, but on a quick check I didn’t find anything related to that.

AnalogWrite in RUI3 is a PWM output, not a “real” analog voltage.
