The description of DMA_CMARx (and also DMA_CPARx) register in single-port DMA (AN2548) says:This register must not be written when the channel is enabled.What wrong may happen if this register is written when the channel is enabled?This of course is ...
Hi,I'm trying to sample data inside an ISR, write it to a buffer, and then write the data in the buffer to an SD card. The SD interface uses the SDMMC devices.It seems that when the ISR interrupts the SDMMC performing a write, the SDMMC errors and re...
i am using NUCLEO-G474RE board, TIM1 to output PWM wave, it works fine ,i can see the pwm wave through scope, but when i use HAL_TIM_PWM_Stop(&htim1, TIM_CHANNEL_3);HAL_TIMEx_PWMN_Stop(&htim1, TIM_CHANNEL_3);to stop PWM , there is a attenuated wavefo...
Also Which is better option to use Single Bank mode or Dual Bank Mode?I want to upgrade my application via bootloader and at the time of upgrade it is not necessary to continue currently running operation.And In DBANK bit ,description is written as ,...
I have made combine hexfile of BOOTLOADER+Application and i want to load that hexfile using STVP utility. But can not find STM32G483 MCU in device selection of STVP tool.As before i were using STM32F030CC mcu which is available but can not find STM32...
Hi,I try to wakeup STM32G471 with RXD, but always failed. and there is so little materials. Would you please help share the complete demo source code?Thanksbr**** Bing
I'm trying to set up DMA to DAC waveform generation on the G474 using CubeMX for setup. I have the device configured as follows:TIM6 at 10KHz, Trigger Out on updateDAC1 OUT1, Trigger 6 Trigger Out eventDMA configured for DAC1_CH1, DMA1 Channel 5 circ...
As shown in below my kit screen is completely white, is not able to see any menu?I have searched to how to boot the kit from STM website, I found a video and an document I want to do the same process, during doing the same procedure I am getting the...
Hi all:I have a bare-metal firmware running on an STM32F407VGT6, and I am implementing a CAN bus interface. It is a very simple "slave" device that responds to short commands.Most basic CAN bus operations are working, but I still haven't finished the...
Hello,I am using STM32L011 MCU and STM32CubeIDE environment. After generating project with CubeMX and even deleting initializations in main function, 'Build analyzer' section shows that 76 % of RAM memory (of total 2KB) is used. What might consume so...
