I made a simple cubemx project for a stm32f722 uC, just configure the clock and nothing more.I enable PLL with HSI to get 200MHz of systemcoreclock. I debug the project running step by step. Inside the SystemClockConfig if (HAL_RCC_OscConfig(&RCC_Os...

I'm using follow code:volatile unsigned int *DWT_CYCCNT = (volatile unsigned int *)0xE0001004; //address of the register volatile unsigned int *DWT_CONTROL = (volatile unsigned int *)0xE0001000; //address of the register volatile unsigned int *DWT_L...

I've created a STM32CubeMX project for stm32f411re uC and try to add CMSIS DSP suppor. I go to "Aditional Software" -> ARM.CMSIS and check CORE 5.3.0 and DSP 1.7.0. Into DSP I chose Source. CubeMX download the CMSIS package into STM32Cube/Repository/...

I was usig stm32f4 hal version 1.11 and in that version there was this code:void I2S_DMATxCplt(DMA_HandleTypeDef *hdma) { I2S_HandleTypeDef* hi2s = (I2S_HandleTypeDef*)((DMA_HandleTypeDef*)hdma)->Parent; if((hdma->Instance->CR & DMA_SxCR_CIRC)...

becouse of this problem:https://community.st.com/s/question/0D50X0000AAIIetSQH/i2s-dma-complete-transfer-irq-on-circular-mode?t=1546553719139I need to use stm32f4 hal library version 1.11I cant generate a project with CubeMX 5 and using that library ...

This issue is not present on f7 v1.15 so the workaround is tu use last cubemx 6 and generate code using CubeF7 v1.15

BTW, this problem is not present on cubeF7 v1.12The problem on v1.16 is that RCC->CFGR is equal to 37898 instead of 0 as soon as the main function is running. This produce that __HAL_RCC_GET_SYSCLK_SOURCE() will be 8 instead of 0.I've notice some def...

it's a cubemx generated file, I didn't change anything.thank

Hi, it's a custom board, but as i use HSI + PLL I don't think that it is related to my board.I attache an ioc file, as you can see it just config the clock and nothing else. If I use the PLL (with HSI or HSE) the generated code fail. If I don't use t...

I'm very confused.I create a new empty project using SystemWorkbench IDE. I don't include HAL library, just startup file.Then create a main.c file and write:volatile unsigned int *DWT_CYCCNT = (volatile unsigned int *)0xE0001004; //address of the re...
