Posted on May 25, 2015 at 03:50 Hi, I'm running some tests on an STM32F072 to verify my understanding of the docs. Apparently I'm missing an important point regarding the NVIC and pending interrupts... I'm single-stepping through the code ...
Posted on May 27, 2015 at 20:24HelloCan DMA access SRAM at the same time the CPU is accessing it or vice versa?Thanks.
Posted on May 22, 2015 at 16:18Estimated colleagues, following I explain the strange behavior: I am working the STM32F407 ARM processor, compiling with the GNU Tools ARM (4_9-2014q4) , use the HAL provided by STM32CubeF4 v1.5.0, using...
Posted on May 21, 2015 at 12:39Hi, I want to execute my code from SRAM of STM32F100. I basically want to copy a program from flash to SRAM and execute the program from SRAMPlease help me understand how this can be addressed.Regards Tejas #flash #...
Posted on May 27, 2015 at 15:33Hi, I have discover there is one extra ghost byte is sent in SPI. I have monitor the memory area of DMA TX buffer, the data there is correct, but I will receive one extra byte in the beginning.Here is my code/* Buffers...
Posted on May 27, 2015 at 09:51Hello there,I've noticed that the in my application the start-up time, i.e. the time from power-up to the first instruction in main() is about 7 to 8 ms. This seems very long to me.I'm using a STM32F103RC and the IAR c...
Posted on May 27, 2015 at 03:29Hi, I'm writing a bootloader, and need to determine the device density and flash size. I can read the flash size OK, from memory address 0x1FFFF7E0 However I can't seem to read the ''MCU device ID code'' , which is des...
Posted on May 27, 2015 at 09:56 Hi, I'm using spi to read and write from an spi flash part, which is working the vast majority of the time. Occasionally I get an incorrect value. Looking at the signals on a logic analyzer the spi clock s...
Posted on May 20, 2015 at 11:35 Hi, I would make a loopback with my board STM3210C using USART2. I use the code /public/STe2ecommunities/mcu/Lists/cortex_mx_stm32/Flat.aspx?RootFolder=https://my.st.com/public/STe2ecommunities/mcu/List...
Posted on May 23, 2015 at 07:33 Hello again, Im decided to switch my first project stm32 from the HAL driver library to the SPL. I was able to get a blinky program working using the STCubeMX software and Kei1 with the HAL drives, but i wa...
