Hi, I'm developing a product using the STM32G030C8T6. I set the I2C using the STM32CubeMX (settings attached) and used the functions supplied by the LL library. The I2C is set as Master and I only have one Master and one Slave on the bus. I manage to...
I am trying to use the DAC feature of Nucleo-H503.Pinned the cube MX and wrote the code.However, the program does not work after entering the MX_DAC1_Init() function, created by Cube MX.I checked in debug mode and found an error in the syntax below./...
Hello all,I am trying to scroll an image in the STM32F746G Discovery Board, using the Scrollable Container widget that is available in the Examples of Touch GFX Designer through STM32CubeIDE. But unfortunately the image is not scrolling and displayin...
Hello.I am considering a project to exchange a small amount of text data using only an STM32G0 microcontroller and a USB memory stick.As a candidate, I found the following microcontroller which supports USB2.0 FS device and host controller.STM32G0B0V...
I have stm32f407vgt6 from devebox. At first, I wanted to do led blink and it worked fine when I supplied it with external power via 5V pins. Then, when I tried to use UART pin (PA_9, PA_10) to print something to USB to TTL module, it did nothing. UAR...
Greetings,I'm struggling to get GPIO configuration to work without hitting the HardFault_Handler. If I configure a single GPIO, like this:__HAL_RCC_GPIOB_CLK_ENABLE();GPIO_InitStruct.Pin = GPIO_PIN_7;GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;GPIO_I...
Hi, I am having trouble getting the Timer to trigger a DMA -> SPI operation. Namely, I want to set the timer up to run,. Then, get every overflow event to trigger the DMA to move a byte into the SPI. The SPI should auto-send. Then, the cycle rep...
Hi all,I use STM32CubeIDE version 1.12.0 and STM32CubeMX Version: 6.8.0-RC4.The MCU used is STM32U585When i start my software in debug mode, some times a HardFault is detected on SysTick_Handler function.If i use the IWDG (with compilation option nam...
I've been writing apps using the STM HAL drivers for a while. I'd like to move to the low level drivers in order to have a better understanding of what's happening in my app. Comms over a UART with DMA is a critical part of most of my apps so I'm s...
Dumb question, can the DMA perform separate, parallel operations with the different channels? For example, could I use the DMA to transmit with the UART and the SPI devices at the same time without one interrupting the other? I'm unclear from readin...
