Read Vrefint in STM32F105VCT7

SPeri.1 · ‎2024-03-17

I want to get an actual voltage reading at VDDA and I have configured the Vrefint adc channel. I saw in another questionnaire mentioning VDDA = 3.3*(VREFINT_CAL/VREFINT_DATA). But it seems like no macro exists as VREFINT_CAL. How can I read the VDDA value?
