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 24, 2016 at 19:34 Hello, I would like programming SPI communication betwen master and slave. With STM32CubeMX generated code for Keil with config for my board. In Cube activated SPI1 and HalfDuplex mode, other leave default....
Posted on May 25, 2016 at 18:20Hi, I'm setting RTC for wakeup interrupt using HAL as below but the interrupt not happen. Please give me your advice. Thanks. P/s: - These codes are based on CubeMX. - Other settings required for system running is ...

Posted on April 29, 2016 at 17:30 I would change uart in CDC standalone example for STM3210E_EVAL by uart1 to uart2. I changed the code in this mode: /* Definition for USARTx clock resources */ #define USARTx USART2 #define USARTx_CLK_...
Posted on May 24, 2016 at 23:31I am using an STM32F4 for a project that undergoes in-field upgrade. The upgrade involves a soft reset, but I would like to back-up some critical data that will ‘persist’ through the upgrade. Since the data that needs ...
Posted on May 25, 2016 at 13:23Hi All,I'm using a STM32F7 Discovery board. I am using the example application (unmodified) from Cube for being a USB MSC device.When I run the code with the debugger connected (using ST Link) everything works as expec...
Posted on May 11, 2016 at 12:22 Hi, the latest CubeF4 HAL (but I suspect that this nasty bug affects ALL HALs), doesn't properly handle the global UART state when working in DMA mode. For example, if the HAL_UART_TransmitDMA() is used, this set...
Posted on May 24, 2016 at 12:55Hello Everyone, I am using STM32F411RC. Here i want to store a variable as static. We can say that if we power off the MCU then also it will have same variable. how can i do that. I want to Read and write in SRAM or Fl...
Posted on April 26, 2016 at 08:50Hi, As per UM1749 User Manual (Description of STM32L0 HAL and Low-layer drivers) the Low Level API should be found in: ''The Low Layer files are located in the same HAL drivers folder'' Figure 8: Low Layer driver fo...
Posted on May 24, 2016 at 12:23Hi I am having problems getting the external crystal oscillator to run correctly. It has a dc offset of approx. 1.5V but a peak to peak of only 380mV. The circuit is based on the STM32F429 Discovery board which produce...
