When flashing the program, CubeIDE shows "Successful", but functions are not realized. We have checked the connection between PC, STM32, DAC(AD5791) and power supply is correct, but the LDAC pin of DAC keeps showing "high" and the pin on STM32, D1, w...
Why is the high level range 0.7VDD~VDD and the low level range 0.3VDD~VSS in Table 21 of STM32F103xC, STM32F103xD, STM32F103xE (DS5792 Rev 13), while the rise time in Figure 19 ranges from 10% to 90%?
We have been using the STM32H735G-DK eval board for a while with no issues with the STM OCTOSPI interface which is connected to a S70KL1281DABHI023When switching to our target we had to change to using a S27KS0642GABHI020 HyperBus RAM device.We have ...
Hello, STM32 community,I’m currently working with the STM32U5 and using the DCMI (Digital Camera Interface) to interface with a ADC Module which has a pixel clock and outputs 14-bit parallel data. While I understand that the DCMI supports extended da...
This code doesn't write anything:*(__IO uint16_t*) 0xD0000000 = (uint16_t) 0x01;However, this code does write:*(__IO uint16_t*) 0xD0000002 = (uint16_t) 0x01;As you can see, the only difference is the 2 vs 0 at the end. The 0xD0000000 address is defin...
Hello,I have my STM32U575 set to wake-up from standby-mode by the reset button of the Nucleo-U575ZI-Q. Furthermore I want the MCU to wake-up periodically triggered by the RTC. The sample code below just makes the reset button work but the RTC doesn't...
While older MCU needed an EXTI line enabled to allow RTC alarm to wake up the CPU from Stop, for STM32U5 both RCC->APB3SMENR (11.8.44) and RCC->SRDAMR (11.8.45) mention a requirement to allow the RTC lto wake up from Stop modes. No further explanat...
I've taken over this project that is using the STM32h755 CPU. The software is not currently using the Cortex-M4 processor inside the chip. I'm reworking the software so that it will be able to use it sometime in the future. But, until then, I was hop...
I am currently using STM32CubeIDE and want to input an external sine wave. The signal has a voltage of 2.6V and a frequency of 10kHz, and I am using DMA + TIM + ADC. The following is the screenshot of my settings. Currently, I can only capture the pe...
HI, i use CC2 on TIM1 set as input capture measuring pulse period and store in array /* USER CODE BEGIN TIM1_Init 1 */ LL_DMA_SetPeriphAddress(DMA1, LL_DMA_CHANNEL_3, (uint32_t)&TIM1->CCR2); LL_DMA_SetMemoryAddress(DMA1, LL_DMA_CHANNEL_3, (uint...
