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 everyone ; I dont know if this is the right place to write ; we are using stm32f429 in our products we use about 20K / year . we are doing the plan for the next year we are getting a long ..very long shippng dates like 80 weeks ! even now we...
I'm attempting to connect an adafruit SD card reader via SDIO to a Nucleo L476RG.I'm reading through the source code to do a test of the basic read/write functions.Initialization and getting card info is successful. if (HAL_SD_Init(&hsd1)!=HAL_OK){...
Hello,what is the difference between configuring GPIO pins from software and leave as default(no code). does it have an impact on other register settings that are not being set/clear in default configuration. because I am having a problem when I leav...
I'm trying to use memory-mapped QSPI with STM32H743XI, but it always crashes when reading the last few bytes (something like 96 bytes before the end address, but not entirely consistent). It crashes without a fault and just disconnects the debugger a...
According to the STM32H747xI/G datasheet, the STM32H747IG has a VCAPDSI pin, but no VDDDSI pin at all.I'm sure i get something wrong here, because without VDDDSI pin, the VCAPDSI pin would be a miraculous source of energy! But seriously: do i have to...
Hello everbody!Im new to the STM32 platfor, and i want to learn about it. For a personal project i want to make de device that tracks a crypto valuta. Just for fun.I have a ESP8266 with the AT firmware, and I could send commands via FTDI using putty....
On this site:https://www.st.com/content/st_com/en/arm-32-bit-microcontrollers/arm-cortex-m0-plus.htmlit says that STM32G0 have bit banding, other sites state that Cortex M0 and M0+ don't have bit banding, also I can't find a define of SRAM_BB_BASE an...
Dear all,I was trying to verify STM32F479 and STM32L476 microcontrollers compliance with SD memory card version 3.0. Both reference manuals state "Full compliance with SD Memory Card Specifications Version 2.0".Using HAL functions provided by ST I ha...
I am trying to set up a hal can receive interrupt. After thorough googling, I found that HAL_CAN_Receive_IT is deprecated and that I should now be using HAL_CAN_ActivateNotification with a callback function. Unfortunately no one describes how to do t...
Hi all,In the past, I've used HAL_UART_Transmit() with HAL_UART_Receive_IT() which freeze RX interrupt in case of RX interrupt while TX is still processing (see https://community.st.com/s/question/0D50X0000AhPrkRSQS/haluarttransmit-with-haluartreceiv...
