I'm using STM32l152 and use TIM5_Ch2 for generate pwm .My target frquency pwm is 2.85 KHz .I using these parameter:clock frequency = 32MHz htim5.Init.Prescaler = 6; htim5.Init.Period = 100; I measured pwm on oscilloscope and I measure 2.85KHz with 5...
Hello, I'm trying to understand the peripheral to peripheral transfers. I'm pretty sure my setup is correct but it's not working and I don't think I understand enough to know what to look for to troubleshoot. For my test I simply have uart1 rx connec...
HiI wish to use an external clock into PH0 from an oscillator module already present in my design.Does this mean PH1 becomes a spare pin?ThanksAndy.
Hi to all,I need to send on every TIM interrupt a packet stream to SPI1. I can't use the HAL_SPI_Transmit(...) because it is blocking....so I need to use the DMA but not in circular mode.I can not use the synchronization of DMA with lptim using DMAMU...
I have Run blinky code USART code with STMCUBEMx and atollic studio now I want to implement I2C communication between Nucleo boards. I searched And download stmcube MCU Package for STM32F1 series I have put it in the same workspace (same worksp...
My target is :my device when the main run is OFF = SLEEPThen its right this code ?When i pressed for a time > 300 mses button (OFF/on ) my device must wakeup , my button il connected to pin wakeup this is my code Which timer and i must use for t...
I am familiar with the STM32CubeIDE; I've done several of the examples and understand how it works on a basic level. What I need to do is create a user-interface (hence needing Python) that will allow a user to interact with the microcontroller. Ctyp...
Our STM32F7 no-OS system calls HAL_MMC_ReadBlocks_DMA() to read multiple blocks of data from eMMC storage.The STM HAL sets the MMC state machine SDMMC_DTIMER register at the start of the DMA.The DMA completes and our code receives the interrupt and h...
