Hello everyone,I am currently using the STM32F207ZG in my project, but I am considering replacing it with STM32F407ZG due to speed.After reviewing the two MCUs, I found that the cores and memories of the two MCUs are different, but the peripherals ar...
How to set the clock source for TIM3 We are trying to use TIM3. We also want to use an external CLK as the clock source for TIM3, but we don't know how to set it. .ioc file - Where should I change the TIM3 clock source settings?
i have MCU circuit with stm32g474met3 as the processor, designed such that it controls the main board charging circuit and it keeps burning randomly at random times could be 5 hours or 20 minuts or even few days I cant figure out why, it burns whethe...
Hello,The STM32L476 MCU is not booting, and it seems to be stuck at address 0x08000228, as shown in the attached image. It used to boot and work correctly before.At some point, it stopped booting and no longer functions as expected. What could be the...
Hi all,I am pretty new to ST so bear with me.The controller is reading in voltage values into the ADC and sending to PC over serial withCDC_Transmit_FS((uint8_t*), buffer, buffer_length)I'm getting the data stream, but the values as read in python fo...
Posted on October 02, 2012 at 10:50Hi! I am trying to use the CS43L22 in a very simple way: only to amplify an analog signal created with the internal DACs of the STM32F4. On the Discovery board the output of DAC1 is routed to AINxx. So I create a 0...
We have a device with corrupted SRAM2 content that is failing in the field. Is clearing the SRAM2 when booting the unit using its ROM bootloader possible? I tried to read SRAM2 content by the serial port when it boots by the ROM bootloader, but it fa...
HelloI am testing new MCU's. I have a ST-Link V2 and using a STM32F401CCU6.At the start I had a simple LED flasher application however after I could not run it I started stripping everything out.This is when I saw that I can actually not even run an ...
Hi, I would like to identify the source of the interrupt that caused the MCU to wake up from Standby mode. To do this, I check the RTC_FLAG_WUTF and RTC_FLAG_ALRAF/RTC_FLAG_ALRBF flags after the system wakes up to determine the wake-up source. Howeve...
Dear ST Community member,I hope you all are doing well.We are using STM32G473VET6 and IMP34DT05TR for Audio acquisition. The PDM Microphone needs a 2 MHz clock signal to operate properly. However, we are getting an error after configuring PLLQ at 2 M...
