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 23, 2016 at 12:15Hello, i have an application that should restart from time to time (bootloader). Currently I do NVIC_SystemReset(). But it seems that only the CortexCore and not the internal peripherals are reset. Some of the CubeMx F...
Posted on May 02, 2016 at 08:23While programming the flash memory cannot provide instructions to the processor for execution. So you can only run programs from cache (which you processor doesn't have) or RAM. I expect that your code writes a group o...
Posted on May 21, 2016 at 03:46 Hi, I am trying to configure timer 1 channel 3 to output a varying signal in output compare toggle mode and driving the CCR with DMA1 channel 5. Thus far I can get the DMA transfer triggering using the TIM_DMA_...
Posted on May 23, 2016 at 08:35How can I use the SPI to write to SD_Card (with HAL lib.) because CubeMx forces me to use SDIO which I have no access to it.is there is an HAL example using SPI to drive the SD card?
Posted on May 23, 2016 at 01:07I have a 5 liner 'c' code to copy a module into ccmram which I put into the .init section which works fine. However, immediately after this function, libc_array_init() is called which results in a hard fault. I think t...
Posted on October 24, 2015 at 20:23I designed the following circuit to interface an STM32F070 Micro for a project I'm working on. I was hoping to get some feedback if I was doing everything the right way/will it work , before I order the PCB and BOM...
Posted on May 21, 2016 at 12:11I would read and write about 10kB of 64kB SRAM internal with STM32F103ZE.This micro have the SRAM at start address 0x20000000.How can I use and save the area of RAM, sure this area isn't changed in real time during the...

Posted on May 19, 2016 at 23:09In linux STM32CubeMX v4.14.0 doesn't allow NVIC priority changing. Under the Configuration tab / NVIC Settings after enabling an interrupt the Priority and Sub Priority fields are still read-only and fixed at 0,0 so al...
