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...
Posted on May 04, 2018 at 13:07i have a STM32F4-Disco configured SPI1 / SPI2 as slaves to observe the in- and output of an external SPI-device (done with CD4021/CD4094 shift registers) and output something on SPI1 (MISO PB4) . SCLK goes to PB13 (SPI...

Posted on January 31, 2018 at 15:53Hi, I am trying to implement variable message length UART reception using USART IDLE IT and the DMA on the STM32F072 as detailed in this very helpful https://community.st.com/0D50X00009XkW2nSAF. I have discovered t...
Posted on May 06, 2018 at 02:29Much frustration. Virtual COM driver works perfectly with CDC on Win10. Supplied DFUSE drivers apparently are not completely compatible. Anyone got a clue as to which USB driver and gotten from where will actually w...
Posted on April 23, 2018 at 18:55My STM32F405 widget uses the DFU bootloader to reflash: the user holds down several buttons in a super-secret pattern, and my firmware jumps to the bootloader..... at which time DeFUse software can a) reflash over ...
Posted on May 04, 2018 at 20:36When trying to set up RCC as the following using Cube, the microcontroller seems to crash. RCC_ClkInitStruct.AHBCLKDivider = RCC_SYSCLK_DIV8; I checked that the RCC_SYSCKL_DIV8 macros (and higher options) actuall...
Posted on May 04, 2018 at 14:50When using Analog or Digital In/Out on any of the available pins on the board, the LCD screen shows corruption and artifacts. In addition, there is unusually high noise when reading Digital or Analog level from any pin...
Posted on May 04, 2018 at 15:24We are using STM32-767ZI and copying a small array into a memory area which is mapped to an external FPGA.Looking for how to make the copy in a single bulk operation.The options are:1. with a loop: while(i < des...
Posted on January 12, 2018 at 12:46Hello,I am trying to implement a long 1D capacitive touch slide sensor or around 7 or more separate capacitive touch buttons using STM32F103. I read that the touch sense library is not available for F103. Is this c...
Posted on October 20, 2015 at 18:18Hello Community! I would like to know how, where, and on what conditions the DMA safety is ensured in STM32F7 HAL drivers and how DTCM is considered in them. I've generated a Cube-Project with freeRTOS for SystemsW...
