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...
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 19, 2015 at 12:01I'm using the DALI library STSW-DALI001 but it doesn't memorize the DALI data in flash. The only data memorized is the assigned address from master module but all other, as SCENE or GROUP assignement are always reset t...
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...
