STM32C071 internal temperature measurtement
HI, how do I read the temperature value of a STM32C071 ADC and convert it into °C using DMA? I cant find any formula in the datasheet. BR Matthias

RTC LSE not working with VBAT on poweroff
I am working on an STM32 device with TrustZone enabled, and I am using the RTC with backup domain powered by VBAT. My RTC is initially configured while VDD is present, and after power-off, the time is supposed to be retained using VBAT.When I use the...
Resolved! DBP bit couldn't be set to 1
I want to use stm32f103rct6 inner RTC, I write some code as below to active RTC, But I found I couldn't set DBP bit of PWR_CR reg to 1, __HAL_RCC_PWR_CLK_ENABLE(); __HAL_RCC_BKP_CLK_ENABLE(); LL_PWR_EnableBkUpAccess();when I debug the re...
STM32U3 Workshop - NFC
Hello STM Community - This post is in reference to the recent STM32U3 workshop webinar. I worked through the rather involved / complicated setup associated with the NFC example. Once the code was generated, 23 errors were returned during compilation....
Prevent manual power cycle after updating with RDP level 1
Hi,I am currently trying to update my STM32L433 on my custom board and I am having some issues with the RDP level 1.When receiving the blank boards (not programmed yet), I use a RPI with OpenOCD and a JTag to update the chip. When I set the RDP level...
Does enabling MSBFIRST change the position of the parity bit in the USART frame?
Hi everyone,I’m working with an STM32L5 USART and trying to clarify a point about parity vs. MSB-first transmission.From the reference manual (USART parity control / frame formats), when parity is enabled the frame formats are shown as:M=00, PCE=1: S...
SGONAK does not trigger global OUT NAK status in RxFIFO or GONAKEFF interrupt
I have a situation where a USB endpoint stops working due to a control packet being NAKed in the handshake phase. I've traced the problem down to the STM USB stack setting DCTL.SGONAK = 1 in response to an INCOMPISOOUT event, yet in the case when it ...
Resolved! STM32F030 datasheet: Misleading VDDA vs VDD sequencing description?
Split from: Power Supply for STM32F030 Cortex TSSOP20 VDDA and VDD pin; specifically this post.@TDK wrote:that satisfies the condition. But only the "VDDA >= VDD" condition - it doesn't satisfy the "VDDA must be first" condition. As noted, I suspect ...
