STM32C071 Do we need Vref for the internal temperature computation
A new question moved from this thread. In many examples they use the Vref int for the calculation of the temperature. Do I need it for the C0 also or can it be done without?

Hi STM32 community.I'm working on an embedded system which uses a RK3399 CPU (running Linux, functions as a USB host) and a STM32F302CC (Runing FreeRTOS, functions as a USB device). This runs on a custom motherboard. They communicate with each other ...
Hello everyone,I am currently working on a project using the STM32H755 microcontroller, and I am facing an issue with the program getting stuck in the `Reset_Handler` during debugging. Specifically, the code halts at the instruction `ldr sp, =_estack...
Hi, I'm stuck on a problem with setting PWR_CR_VOS on NUCLEO-32 STM32L031K6- I want to select HSI16-PLL as clock source- VDD is 3.3V- FLASH latency is set to 1WSBut I can only set PWR_CR_VOS to RANGE 2 and RANGE 3.RANGE 1 cannot be selected, so I can...
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
Hi. I have a newly purchased NUCLEO-U575ZI-Q. I followed the instructions here to install the toolchain on Windows 11:https://www.st.com/en/evaluation-tools/nucleo-u575zi-q.html#documentationhttps://wiki.st.com/stm32mcu/wiki/STM32StepByStep:Step1_T...
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...
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...
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...
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 ...
