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 January 03, 2016 at 23:37Hello all,While using USB as a mass storage (STM32L MSC, FS_Device_Lib_4.0), can MCU read PC system time and update RTC date/time accordingly?Any idea how to do that or any sample code? USB MSC configuration for ST...
Posted on January 03, 2016 at 21:20I want to output the max 48MHz clock signal on STM32F030 to drive another subcircuit. The problem is the chip STM32030F4P6 (TSSOP-20 package) I prefer to use doesn't have the MCO pin (PA8). So I have 2 questions: 1...
Posted on May 12, 2014 at 09:29Dear all, i am using STM32F405 with internal osc. clock. I connected a 3V lithium battery as VBAT, and would like to use the RTC to keep time when power is off. I read some samples here and there and implemented some R...
Posted on June 10, 2015 at 23:34Hi,We want to add a cell battery to keep time and date. but in the schemaitcs, Pin 1 and Pin 6 in STM32F429iDisco for VBAT alredy connect to +3V.What we can do?Thanks a lot
Posted on December 31, 2015 at 21:31Hi guys!Is it possible to use only assembler startup code without any libraries to create project for STM32F7? When I'm trying to include SystemInit() function in stm32f7xx.c file, I must include core_cm7.h header...
Posted on December 31, 2015 at 19:15Dear Friends and Colleagues!I'm interested to move from NXP chips to ST ones, so I've got a pair of devices and am currently trying to work with their bootloader via UART. The devices areSTMF030F4 (TSSOP-20)STMF03...
Posted on December 31, 2014 at 19:02hi every one i am a new elementary user of stm32f4xx(in particular stm32f4 discovery board) when i need to learn some new peripheral and that's application and functions, i Encounter a lot of Terms that i can not ...
Posted on December 31, 2014 at 17:20 Hi, I have a problem with proper main clock configuration in STM32F030K6T6. I've connected an external crystal 16 MHz with 2x15 pF caps, but the HSE is not starting. Variable HSEStatus remains 0, so the PL...
Posted on December 31, 2014 at 16:02 hi every one is there any special function for this purpose ? i am currently read characters byte by byte and compare them with desire character but i dont know why it does not work some time my way ...
Posted on December 30, 2014 at 04:46I goofed, big time. I'm new to the STM32F and I didn't follow the STM32F4 discovery schematic. I built a board that I wanted to power up from flash, and while I remembered the BOOT0 setting (GND), I left nRST floa...
