Posted on May 21, 2016 at 22:39I'm having some difficulty getting the default HID or VCOM projects to run properly. I've set the HSI input and let the clock configuration do its thing. The projects compile fine, but when I try to run them on a Ma...
Posted on May 23, 2016 at 14:00Hi,I need to distinguish between diffrent types of STM32 devices during runtime .Specifically between F2 and F4 and their sub types. Can this information be parssed from the Unique ID?Is there a way to get at runtime t...
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...
