STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Hi,I see an alias, using DFSDM (sinc3) and a PDM mic at 16kHz, while a speaker produces 1...24kHz.The spectrogram is attached.As I understand, the DFSDM filter has a notch at 16kHz rather than at 8kHz, and attenuates 8kHz for 12dB only.Is it possible...
I am trying to figure out SPI communication between two microcontrollers: I have an STM32H755 Nucleo and a Nucleo G47RE. I tested basic communication by shorting MOSI and MISO on both boards separately, and it works in full duplex master mode. Both c...
Hi, I want to generate a 1 microsecond (1 µs) timer interrupt on the STM32G0B1RCT6 microcontroller using its internal clock(16MHz). I am currently using a 16-bit timer to achieve a 5 microsecond delay, but I cannot achieve a 1 microsecond delay. My q...
HiI am using STM32L476ZG MCU development board. I created a new project without adding any interrupts. I noticed that FLASH->SR = 0xC0 at reset and when I try to clear it, it comes back after the next command I execute.I'll add screen shots to clarif...
I am using STM32H503CBT6 with a frequency of 250MHz, but my program is not running. I have a counter variable in a while loop, but it is not incrementing. When I lower the frequency to 100MHz, the program works. Please help me!
In the Cortex-M7 (AT610) and Cortex-M7 with FPU (AT611) - Software Developer Errata Notice published by Arm on May 28, 2024, document version 11.0, at the end, is listed a new bug affecting debug sessions:3092511 - Cortex-M7 can halt in an incorrect ...
Hi, I am trying to communicate via FDCAN with a board equipped with a STM32G0 by using this library https://github.com/owennewo/SimpleCAN I already tested it successfully with both STM32H743 and STM32H723 but I am having troubles with the G0 When I ...
Hi, I'm using a STM32F407VGTx, trying to use MQTT on this microcontroller.I first made a test program on a NUCLEO dev kit (also a F4 controller) and it worked.Now I get an error and it doesn't want to connect to my PC which is the broker. I have trie...
I used thisBSP_OSPI_NOR_Write(uint8_t* pData, uint32_t WriteAddr, uint32_t Size) fromhttps://github.com/STMicroelectronics/stm32-external-loader/blob/main/STM32L4x_boards/MX25LM51245G_STM32L4P5G-DK/Sources/Library/stm32l4p5g_discovery_ospi_nor.c but ...
Hope all is going well. I'm trying to ping STM32H743ZI NUCLEO 144 using LWIP middle-ware. Code generated by CubeMX. Configurations: Set the HCLK to 400 MHzEnabled the CPU ICache and DCache (under Cortex_M7 Configuration)Enabled MPU (Region0, Region1 ...
