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...
Hello to everyone,recently I've got STM32F769I-DISCO board with B-LCD40-DSI1 that contains 4" LCD and touch panel. But it hasn't been a single day that I knocked over the board and broke the touch panel so it doesn't work now. So now I'm searching fo...
Hello,I'm using the RTC Alarm to wakeup the MCU every 10min and after 10PM, sleep for 10 hrs. However, I noticed that the RTC just actually sleeps for 8:25 min and when it wakes up, the RTC time says 10minutes have passed. To illustrate:Current time ...
Dear ST Forum Members,I'm experimenting with STM32L011K4T6 Nucleo,with ADC_LowPower Example project, I saw this :uhADCxConvertedValue = HAL_ADC_GetValue(&AdcHandle);If I want to use two channels of ADC, what should I modify,I've done ://ADCx Channel...
Hi all,Using STM32L476.I had some issues with LSE (ready flag is never set), and so I experimented with different capacitors.During our experimentation I tried to intentionally cause the LSE to fail (never mind why) by touching its capacitors with my...
I think that this serves more as information than a question.On page 726, section 26 of RM0360, no mention is made of the memory locations and register descriptions for the unique signature. Nevertheless, stm32f0xx_ll_utils.h makes provision for acce...
Posted on May 01, 2014 at 23:28Hello there,I have an interesting problem. I am writing a hardware abstraction wrapper for UARTs on an STM32F427, and I want this particular implementation to use DMA for receiving data. I am not using DMA to transmit ...
Hi,I have NUCLEO-L053R8 board. I'm started to use Atollic TrueStudio 9.0. So, I would like to monitor the value of a variable, but it seems like it can't be done using on board ST-Link/v2 debugger. I've tried to figure out why... So far, I've got no ...
Posted on July 19, 2017 at 21:40I've used the HAL SD driver in various versions up to and including 1.6.0.Experimenting with the new 1.7.1 SD driver, it appears to get into situations where the DMA and the command response occurs out of order on a r...
Hi. I'm using these lines of codeResult= HAL_UART_Transmit(serial, BufferSerialWrite, BufferSize, HAL_MAX_DELAY);to send data but, after some hours, nothing exits from the uart. I have to reboot the mcu.How can I resolve this problem?The line of cose...
