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 26, 2015 at 14:44We have a solution, which reading audio file from SDCard and playing by I2S. It works ok when the CPU Clock Speed is >= 84Mhz. To reducing the Power Consumption, we have to reducing the CPU Clock Speed to 24MHz, then t...
Posted on May 28, 2015 at 12:13Using STM32CubeMX to generate code for STM32F427ZITx processor. When changing the clock source from HSI to HSE the generated code updates the PLL fields but still maintains the source of the clock as HSI as shown below...
Posted on May 28, 2015 at 11:08Hello,I would like to modify my brownout reset configuration but I do not know how to do it. I generated my code using stm32cubemx software. I am using IAR embedded workbench and jlink for programming the microcontroll...
Posted on May 26, 2015 at 21:23Hi, all. I have an STM32F401Discovery Kit using an STM32F401VCT6. I have wired an external SD card connector and have successfully implemented Elm-Chan's FATFs using the SDIO SD card interface. All works well, I can mo...
Posted on May 23, 2015 at 11:34I have a board with a 32 bit SRAM and have used CubeMX to configure a 32 bit data bus, a 10 bit Address bus with a Chip select of NE1. Briefly, Cube has produced the MX_FMC_Init(); file with settings as follows:- hsram...
Posted on May 28, 2015 at 07:23i brought STEVAL-IEG001V2 from mouser with bulk id Z4T21418E002. but as mentioned in user manual i did not received any Firmware (code for microcontroller). kindly provide any link for firmware. Thanks
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...
