Hi,I know that DMA can save CPU time by transfering data from memory to peripheral (and from peripheral to memory) but it not clear how this works for I2C since the I2Cx_EV_HANDLER is still called when I changeI2C from IT configuration to DMA configu...
#include "main.h" #define ADC_BUF_LEN 9000 uint8_t adc_buf[ADC_BUF_LEN]; uint8_t ch = 0; ADC_HandleTypeDef hadc; DMA_HandleTypeDef hdma_adc; TIM_HandleTypeDef htim2; void SystemClock_Config(void); static void MX_GPIO_Init(void); static void MX_...
Dear ST/reader,I’m currently implementing a uart receive interrupt function for use with the STM32H743 specifically using HAL_UART_Receive_IT(). This is straightforward when the receive length (number of bytes to receive) is just 1 in which case it e...
Hello, I am trying to perform a flash bank swap from bank1 to bank2. Executing the following code: FLASH_OBProgramInitTypeDef OBInit; /* Unlock tha User Flash area */ HAL_FLASH_Unlock(); HAL_FLASH_OB_Unlock(); /* Get the Dual boot configura...
Hi,I am working on a project where I need to add an info bar above multiple screens containing a digital clock.The digital clock is sourced by the rtc of the mcu. For one screen I read the current time and date with HAL_RTC_GetTime/HAL_RTC_GetDate in...
Hello, I would love to add a USB storage device (USB stick) to my terrific new STM32G4 application.But I am frightened, with the STM32G4 USB device interface this is impossible?(or this there some way to come around this?)(or is there any possibility...
Hi, I have started working with MPU and I can see from the examples the potential of this caracteristic. I am developing a safety app in which there are two parts in the program: Safety and no-safety application. Meanwhile the part of the ADC is safe...
Hello,I have just "finished" the ethernet interface for a STM32F7, now we think about also using the USB high speed interface (yes, it needs an external high speed USB PHY), that would be for data streaming, as an alternative for using ethernet, as m...
Hello community,now that STM32F767 + lwIP / TCP is working well, I found that sometimes it takes too long for streaming that the other side gets the data (some other network traffic, or delayed ACKs, or whatever Windows does), and the STM32's interna...
I am planning to use STM32H735 controller in my product.I've a requirement to have 8x virtual COM ports over USB and having a parallel communication without interfering with each other.I would like to know if it is possible and will it create an issu...
