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...
I have STM32G070RBT6, a timer is set to give interrupt every 1 second, in interrupt i am incrementing a variable timer_var1 then in main file while loop i am dividing this by 10 and assigning this value to another variable TIMER_NOW. Now when timer_v...
Hi, I want to write into flash on an STM32WB15 mcu. I have this code, where i write two 32 bit variable into the flash. void Write_Flash_Data(uint32_t new_value1, uint32_t new_value2) { HAL_StatusTypeDef status; HAL_FLASH_Unlock(); // Unlo...
I have designed a custom board using STM32H573IIT3Q MCU. when I connected it with st link, the st link not recognize it. After I check the voltage on power pin, all the power pin is normal except the VCAP pin (not outputing voltage). According to the...
Posted on October 16, 2014 at 14:31Hi everybody!I'm going to use STM32f429 with external SDRAM (IS42S16400J 64MBit) in my project. I'm trying to make FFT for 32768 input buffer, my function calculate it in about 250ms.Functions in CMSIS LIB do it mu...
I need to declare a 'volatile const', meaning that the value is placed in FLASH and that it is re-read every time it is referenced (as the FLASH is written to elsewhere), but am finding it very difficult to accomplish this as the compiler either plac...
I am using stm32g030 RTC. for calibration I send RTC out frequency (512hz) on RTC output pin. when I see the signal on the oscilloscope, the output frequency is unstable. its pulse width are changing constantly and it is not showing me a pure 512hz. ...
I am designing a board based around the STM32F030RC, and noticed an apparent discrepancy on IRQ18 between materials.STM32CubeMX allows both TIM6 and TIM7 to generate interrupts, and the stm32f030xc.h file it generates defines TIM6 as IRQ17 and TIM7 a...
Hello,I was wondering if it is possible to use the FreeRTOS Middleware which is used on the STM32H7 and STM32F4 and which can be found at the following links ‘https://github.com/STMicroelectronics/STM32CubeH7/tree/master/Middlewares/Third_Party/FreeR...
Hi I have configured Octospi1 to Read / Write from my FPGA in memory mapped mode.The interface works well, but i have a problem that the CPU is not reading from the memory and just use last cached value.The Variables are set volatile. both the pointe...
Dear Community,I am currently facing this issue where my STM32 Black Pill F411CE suddenly went into hard fault during runtime. The MCU was permanently gone and was not able to be re-programmed, and four others that I connected to the same hardware we...
