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,I have an question concerning the VBUS Pin which is connected to the STM32L476G Discovery (PIN PC11) directly. Why isn't 5V an problem for the PC11 pin? I thougt 5V would cause overvoltage?
Dear community,I am using the Nucleo-L4R5ZI board with STM32L4R5ZI chip embedded to experiment UART.Unfortunately, I am facing an issue when using interrupts.I looked up through the BSP (STM32Cube_FW_L4_V1.15.1) provided by ST if examples were using ...
I set up DMA for a USART transmit operation with an ST32L412. Settings are 115200 baud, 8 data bits, no parity. I thought everything was working until I noticed the third character in all my outbound data not showing up. It turns out the default BY...
Hi,i designed myself a PCB with a STM32F030 with breakout pin (SWDIO, SWCLK, NRST, GND, UART1_TX, UART1_RX). When I try to debug it with VS Code, it doesn't work. I tried it with stutil, openocd (on st-link v2) as well as bmp (on BMP Bumpy). Nothing ...
Hi everyone,I'm relatively new to STM, i'm making my diploma thesis with it. It's going to be a mini, portable oscilloscope, but at this point I'm totally stuck. I started using ADC with DMA, but soon I realised this might be not the perfect option, ...
we have a STM32L07CBT6 and we want to disable the VREFINT with following HAL functionsHAL_PWREx_EnableUltraLowPower()HAL_PWREx_EnableFastWakeUp()but still want to use the BOR. Therefore I checked the section of VREFINT (6.2.4) and BOR (6.2.2) in the ...
Hi everyone, i'm quite new with the stm. Currently im using the stm32f411 discoveryboard and trying to get the pulse width in order to measure range, i did try to search for solution and find out about input capture method but the code is on sw4stm32...
Hi,I have a custom board with an STM32H745 which doesn't boot / I can't connect to.I've noticed that three of the gnd pins are not connected K15, L15, M15, would this cause the problem?The design is using an external 1.2V supply which is fine. 3.3V i...
I am developing a device that simultaneously logs two CAN lines using the STM32H743.I saw "Wrong data may be read from Message RAM by the CPU when using two FDCANs" in STM32H743 Errata document.I need a detailed explanation of the above Errata.I am t...
