HelloI trying to figure out what the maximum frequency is for the TRACECLK stm32u5A9.I found this post for the stm32h5https://community.st.com/t5/stm32-mcus-products/traceclk-freq-in-stm32h5/td-p/604127does the same apply for stm32u5 were can i in t...
Hello STM32N6 Tech supportI am writing with reference to power on sequence. My power sequence is as follow1. First VDDA1V8_AON, VBAT and VDD is applied. My VDDIO4 & VDDIO5 is also connected with VDD.2. VDDCORE is supplied from an external SMPS step-d...
Hi, Im using STM32g0b1 ADC in continous mode.I am continously converting channels 0,1 and 2. Everything works perfect when clocking the ADC with PCLK/2.SYSCLOCK is 64MHzPCLK is 64MHz so ADCCLOCK is 32MHz.I get End-of-Conversion Interrupts correctly a...
I work on the STM32U5G9J-DK2 and what I noticed, the RTC doesn't accepted properly hour value which is greater than 12. Than calendar doesn't work, don't actuallize and the hours going UP for example from 23 to 24 and from 24 to 25 and so on... It's ...
I have configured the comparator 2 PB6 on the STM32G071RB Nucleo board. It is configured for rising edge interrupt. As soon as HAL_COMP_Start is called on the COMP you can see the EXTI rising edge interrupt flag immediately go high. (well not immedi...
Learning on how to code 4x4 keypad with F411RE I came to need to learn timer in order to generate an interrupt (saying simply C function should be called lets say every 1 second) I created STM32 project CubeIDE+CubeMX selected TIM3 (in Timers) -> s...
We are using the STM32U5 MCU and its internal RTC in our project.We are facing an issue where the RTC time sometimes goes beyond 24 hours — for example, we observed a timestamp showing 37 hours. The RTC is configured in 24-hour format, and we have in...
As shown in the figure, when using one QSPI, the other becomes unselectable.
Good morning,I would like to measure the supply voltage on an STM32H573RI. To do this, I measure VREFINT and then want to calculate the supply voltage.My approach (simplified):sConfig.Channel = ADC_CHANNEL_VREFINT; sConfig.Rank = ADC_REG...
