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...
Posted on May 18, 2016 at 22:44Hello, We want to use HAL_SPI_Transmit function to load the data from 16 bit Array. The function parameters are (SPI_Handle TypeDef *hspi, uint8_t * pdata, uint16_t Size, uint32_t Timeout). Our data buffer is defined ...
Posted on May 25, 2016 at 04:47Hello. Please tell me how to use Flexible static memory controller and the hard disk 40 Gb ATA4 80pin example for any IC and software. I'm not much I do not understand how to use FSMC and HDD can be a NAND Flash / PC C...
Posted on May 24, 2016 at 17:57Hi,I'm using a stm32f429ZIT discovery with the tft.I'm trying to configure the tft. I have a conflict between the usart2_CTS and LTCD_G7.I don't have any usart free, then I need to change the LTCD_G7 to another pin. Th...
Posted on May 24, 2016 at 16:03I'm use STM32CubeMX to configure TIM2 CH1 to compare output, and it works well. Now I want to change it to PWM output when the programm running. Then which HAL library function to call to clear the registers previous s...
