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...
Posted on August 08, 2016 at 19:20Hi all,Is the VUSB input required/recommended for self-powered STM32 USB device?From everything ive read, the VUSB input is required for connection/disconnect detection, but in practice, everything seems to work jus...
Hi,I am trying to use 3 ADCs on STM32F407 with 'Triple regular simultaneous model only'. This option is avaliable in CubeMX configuration, but I can not get it working in the code. I would like to sample 3 channels using the 3 ADCs at the same time. ...
When finish run my code ，those code of enable like __HAL_RCC_GPIOJ_CLK_ENABLE();__HAL_RCC_UART8_CLK_ENABLE();__HAL_RCC_I2C4_CLK_ENABLE();do not change color of purple like the picture still black, this mean i lost some file o no、
Hi,I am working on STM32G474CET mcu. I am trying to use VREFBUFF voltage for ADC channel referance voltage. My configuration looks like the following. When i run the code, it stuck in the HAL_SYSCFG_EnableVREFBUF function. Whenever i check the 'ticks...
Hello,I am new to this cpu and experimenting with RTC wakeup using 32kHz LSE. I am usingthis code for the wakeup: void HAL_RTCEx_WakeUpTimerEventCallback(RTC_HandleTypeDef *hrtc){SystemClock_Config();HAL_ResumeTick();...} // In while(1)HAL_RTCEx_SetW...
Hello there!I've been tinkering around with the STM32H5 and recently I've managed to setup the STM32H563 with SPI and DMA.I'm now trying to understand what is the limit of the burst (either source or destination). I'm using the DMA channel 4 (with a...
Hello, I looked at AN5419 and configured the stm32H725igk6 power supply circuit as shown in the following figure, but the external osc does not work and the st link is not connected to the MCU. Is this product a model that must be configured using S...
Hi !I'm trying to configure the ADC1 to 7 ranks conversion and a GPDMA1 channel (0) in "Standard Request Mode" to transfer the ADC data into the memory.First, I've configured the ADC without GPDMA channel, and it worked fine (Polling mode, no interru...
Hi there!I was trying to emulate eeprom using flash memory. I am using Nucleo-F030R8 board. I was able to program flash 2 times (0xF055 was the test value):however I cannot reproduce it anymore and whilst trying to program I get PGERR.Uploading my co...
