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...
The STM32H7 series has come with the concept of DMAMUX which is different from the older series. it looks awesome and better than the dma request mapping table.But I wonder if it can route multiple dma requests to the same dma stream or not?To be mor...
I am using the CCMRAM to store some large array which should be zero-initialized.My definition for the arrays is similar to:__attribute__ ((section (".ccmram"))) uint32_t large_array[4096];Obviously, there is no constructor for these and there should...
Hello everyone,I want to add a device unique ID (a uint16_t progressive counter that identify my device as a whole, not only the mcu used) at programming time to a stm32f446 based product. Is there a standard known standard way to do this?Maybe it’s ...
stm32f407 read out IPR5 50d0d0d0, document says its Reset value: 0x0000 0000why i got d0
Hi community,I would like to toggle GPIO when operation flash (Erase and Programming)I have tried relocation vector table and code in the ramI have determined vector table and code in the ram，Keil Debug mode show their address in the ram after 0x2...
As the title suggests, im having a problem using HAL to make some USART echo.I tried the same approch on a nucleo-f031 and its working wonderfully.I can print the whole hyperterminal string, but i cant reach the receive interrupt. Even if i set the R...
The official release of STM32G4 was scheduled for the 20th week of 2019, but now we are in the 21st week and there is still nothing. Any problems?Andrea
I am using a STM32L476. I am using the counter mode on the low power timer to generate an interrupt after a given period. When I am in run mode, this interrupt works just fine. However, when I use the interrupt to try and wake the MCU from Stop2, I g...
Hello, I'm looking for the default EEPROM memory values of STM32L0 family microcontroller. I'm using STM32L010K8 with internal 256 bytes EEPROM. I couldn't find any information about the default EEPROM values. When reading EEPROM values using STM32Cu...
Posted on February 03, 2018 at 07:45I want to calculate CRC for large file, the large file have been added the CRC value in the end of the whole .bin file(Get this CRC data via IAR tool). I read the file and calculate CRC of it in part(HAL_CRC_Calcu...
