Posted on May 07, 2016 at 16:00 Reference manual RM0383, ''STM32F411xC/E advanced ARM®-based 32-bit MCUs'', says: 6.7 I2C Status register 2 (I2C_SR2) Note: Reading I2C_SR2 after reading I2C_SR1 clears the ADDR flag, even if...
Posted on May 21, 2016 at 18:17 Hi, I m using STM32F103 Nucleo board and keil compiler. I m using HAL_CAN stack. I configured filter in mask mode and set to receive all messages. Mode : Loopback mode speed : 250 kbps ID : stand...
Posted on May 17, 2016 at 22:02 Hi all, I have recently run into an issue trying to use the HAL_UART_Receieve() function which comes with the HAL library. I am using the Nucle-F303RE board, which uses the STM32F303RE microcontroller. I wa...
Posted on May 20, 2016 at 23:00I'm using the wakeup interrupt from the RTC, but I don't want it active until certain conditions are present.But I have no choice, either I disable it in Cube and get no stubs for interrupts and no definition, or I ena...

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_...
