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...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hi guys,When setting option bytes to boot device from internal flash (at 0x0800_0000), the entire Flash memory region is aliased to start at address 0x0000_0000. But the mapping address of ITCM is starting from 0x0000_0000 to 0x0000_FFFF, so I wanna...
Hey everyone!Some context:We are developing a medical device using STM32H7ZIT6 MCU. We succesfully developed a working prototype, using UART connection protocol. Couple of consistency problems (i.e. the device works flawlessly at times, sometimes we...
I have reviewed the many posts from others that have not been able to jump from a bootloader the application code and nothing that I tried worked.My MCU has its 128kB of flash in two banks, one at 0x08000000 and the other at 0x08040000. When the MCU...
Hi All, I'm using an STM32F1 with a 240x240 LCD screen that comunicates with the micro by SPI (with DMA). The screen uses the ST7789 driver (I supose it is not important). I'm working with RGB565 color format.The problem that I have is, for example, ...
Hi, I observed a limitation in the STM32H7 reference manual saying that "The current version of the SDMMC supports only one SD/SDIO/e•MMC card at any onetime and a stack of e•MMC."So my application requires to control two SDIO slaves from both SDIO i...
I read in the doc for the G431:"The Flash main memory programming sequence in standard mode is as follows:1. Perform a mass erase. If not, PGSERR is set."So i can not do a single page erase??
Hello,I'm trying to implement an I3C target device which sends inband interrupts when I push the blue Nucleo button.But I also want it to be ready to receive data via a private message.To do this I call `HAL_I3C_Tgt_Receive_IT` after receiving a dyna...
I want to use IWDG with stm32f103rct6 chip with ll library. such samples code as below:```static int iwdg_init (unsigned short int expired_ms){/* 开启 LSI, IWDG */ __HAL_RCC_LSI_ENABLE(); LL_RCC_LSI_Enable(); while (!LL_RCC_LSI_IsReady()); LL_IWDG_Enab...
Hi everyone,I am using the NUCLEO STM32-F401RE V dev board and trying to communicate with an MAX31856 temperature amplifier. I am using SPI2 peripheral. I am able to write values on the SPI line. I have printed them out to the UART and have verified ...
Hi guys,I am read the example "STM32Cube_FW_F1_V1.8.4\Projects\STM32F103RB-Nucleo\Examples\FLASH\FLASH_WriteProtection", and want to rewrite it on my board.my code is as follows: HAL_FLASH_Unlock(); HAL_FLASH_OB_Unlock(); HAL_FLASHEx_OBGetCo...
