Hi, I need a little explanation about what is wrong behind my reasoning..I am using STM32F411. reading, two inputs of ADC in scan mode over circular DMA triggered via TIM2 update event.TIM2 is triggering ADC at 100KHz, so I have 50Khz sample rate per...
The STM32H743XGH6 is specified to have 1 MB of Flash memory.However, it seems that the following 2 MB address ranges are writable:BANK1: 0x08000000 to 0x080FFFFFBANK2: 0x08100000 to 0x081FFFFFIf the device really has only 1 MB of Flash, I would expec...
I have strange DMA problem with a F303 application, in particular a STM32F303K8 (a STM32F303x6/8 variant).The concept is relatively straightforward.A configured ADC sequence is triggered by timer, the ADC in turn triggers DMA transfers of the convers...
Hi, For STM32F446RET6, I want to use the DAC function of it. But I have some question. 1. If I don't use the output buffer, what is the output range? From the datasheet I think it should be 0.5mV to 3.3V±1LSB？2. If I use the output buffer, what is th...
I am using STM32WB55 and entering STOP2 mode for low-power operation.RTC Wakeup timer is configured, and the interrupt works correctly in RUN mode,but the MCU does not wake up from STOP2 mode when the RTC wakeup interrupt is expected.Configuration:- ...
Hello dear ST forum.I need again you precious help.I am working on a data acquisition device, and need to get 14bit data from a parallel ADC connected on DCMI pins,at 48MHz, and move it to a 32MB SDRAM (W9825G6KH-6I) till almost full. The MCU is STM3...
Hello,I am in the process of designing a product which is based on the STM32-H753 and requires P/SRAM.However, I'm concerned the H753 might not support on PSRAM with QSPI, I need the PSRAM for write/read.I haven't found any application notes or examp...
hello when i use UART Idle interupt with DMA on STM32H743XIH6 chip,i found ,the interupt function will run imediatly when HAL_UARTEx_ReceiveToIdle_DMA(&huart2, (uint8_t *)Uart2RxBuffer, 50)run,and this is my core code MPU_Config(); // SCB_EnableICa...
Post spread from STM32H745: No device found on target on a custom board Hi, and thank you for your previous answer and for pointing me to RM0399 / figure 22. I am quite new to the STM32H7 power configuration, so I may have misunderstood the datasheet...
Hello, I am trying to make a write into flash driver but I am having some issues.I know that the only way to write a 1 to the memory is by clearing the whole page, but I am having issues writing 0s.By reading the manual I encountered: Bit 2 PGERR: Pr...
