Background:I am using the STM32H747I-DISCO board and the BSP SDMMC example from the ST Repository as my starting point. I can provide my code if necessary but wanted to keep post as short as possible. I have looked at AN4838, AN4839 and AN5200 ST M...
I want to extract data at high sampling frequency ~10KHz at STM32N6570-DK, Is it possible with USART for three channels or we have any other mode for this purpose. I want to continuously stream data at 10KHz sampling frequency.
Hello,Description: I am attempting to generate two simultaneous pulses of different lengths using a single timer (TIM4) and multiple channels.Current Implementation: I am currently using One-Pulse Mode (OPM). In my existing setup, the pulse starts at...
Environment: STM32L4 + 32.768K LSEFunction: Wake up and work once every hour, then enter stop2 mode. During the one-hour sleep, wake up every ten minutes to feed the external watchdog.Problem: The device resets directly when waking up every ten minut...
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...
Hi all,In my project I use several IOs, I2C, SPI, UART, ADC, DAC and most of them work as expected.However, I have 2 inputs from push buttons (pushing the button would set them to 0 volt), set with pull-ups (not set as EXTI) that sometimes stop worki...
The VENC peripheral on the N6 boasts a hardware handshake path with the DCMIPP peripheral, potentially allowing full compression of each frame to occur with very little active RAM. From what I can find, the DCMIPP capture starts, then the VENC is tol...
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...
