Hello, I'm trying read core temperature. I use NUCLEO-U575ZI-Q board. I wrote code: RCC->AHB3ENR |= RCC_AHB3ENR_PWREN; PWR->SVMCR |= PWR_SVMCR_ASV; RCC->AHB2ENR1 |= RCC_AHB2ENR1_ADC12EN; ADC12_COMMON->CCR |= ADC_CCR_VSENSEEN; ADC1->CR ...
Hello ST Community Team, We are currently working with the STM32N657X0H3Q1 device and using an external DRAM – S80KS5123GABHB020 (512 Mbit) connected via the XSPI interface. We have successfully configured XSPI and external memory initialization (usi...
Hello,I was trying to implement extended calibration for ADC1 on my STM32U575 according to RM0456 Rev 5. I have a revision ID 0x3001 chip which should support extended calibration. The chip would hang very badly (can no longer connect with debug pr...
Why is it that when I set the clock frequency of the STM32 to a high frequency (180 MHz), the code will crash, but when I set it to a low frequency (72 MHz), the code can run normally?
Hello,we are seeing a systematic offset when using the internal temperature sensor of the STM32G031G8U6.Over the years we have tested ~50 SoCs (different production batches), and all devices show a very consistent temperature reading that is about 2–...
Hi everyone,I’m experiencing unexpected behavior while testing 9-bit SPI on an STM32, observed with a logic analyzer. The issue only occurs when the MOSI line is physically connected to the slave.Observations::keycap_1: MOSI not connectedCS and SCLK ...
Hello, rm0456 in chapter 33.4.8. talks about "Software procedure to calibrate the ADC" and "Extended calibration mode" on some products. It is not clear, if "Software procedure to calibrate the ADC" is enough for products with "Extended calibration m...
Bonjour à tous,Je rencontre un comportement anormal lors de tests SPI 9 bits sur un STM32, observé avec un logic analyzer. Le problème se produit uniquement lorsque la ligne MOSI est physiquement connectée à l’esclave.Observations ::keycap_1: MOSI no...
Im trying to run SYSCLK from LSI on a STM32C011. But it appears as if the MCU is not running. I cant see anything in the datasheet that says the clock cant be used and it can be routed fine in the clock configurator. Am I missing something in the dat...
Hello all,We are testing LPUART wake-up from Stop 2 mode using the STM32CubeU0 LL example:STM32Cube_FW_U0_V1.2.0/Projects/NUCLEOU083RC/Examples_LL/LPUART/LPUART_WakeUpFromStop2_InitWe made a minimal modification to the example:Replaced LPUART1 with L...
