Hello, I am very new to STM32 MCUs and hoping someone can explain to me the HardFault_Handler and possible reasons why my code is jumping to here? If there is a good resource which discusses this, that would also be very useful but I haven't been abl...

Hello,I am trying to use the memcpy function to transfer data from the ADC data buffer to a separate data buffer, but when I call memcpy, only the first 1400 of 6000 samples gets copied, while the remainder of the buffer does not get updated. I notic...

Hello all,I need to store 6000 incoming samples from the ADC, analyze these 6000 samples and then store 6000 new samples in the same location and I need to do this repeatedly. I am using HAL_ADC_Start_DMA function to start the channel and I want to u...

Hello,I am working on a project where I have created several of my own files (.h and .cpp) but I am having issues with undefined reference to certain functions. I cannot solve this issue while having the files separated, but I was wondering if it is ...

Hello everyone,I am using the STM32F413 Nucleo-144 development board to generate 2 sinusoidal wave forms at 60Hz. To do this, I have DAC_OUT1 (PA4) and DAC_OUT2 (PA5) conversions running through DMA. The signal from PA5 appears as expected when I mea...

I solved the issue by having a closer look at the data in memory as it was mentioned as one of the possible reasons for entering the HardFault_Handler. I was writing data to an array of a set size however I did not have any constraint on how many sam...

For this specific project, I am analyzing 6000 samples on an ADC per second to complete further computations based on the received signal. I am using HAL libraries and custom code. I have implemented a buffer within the putchar function used by print...

I had not realized that I had the incorrect size in the memcpy function. I changed that and got the expected output, Thank you!

So when the array is full, the HAL_ADC_ConvCpltCallback function is immediately called? Can I then start the ADC again using the same array (once the previous samples have been analyzed) and it will not call this callback function until a new 6000 sa...

I know this concept and I have done this already, however I am trying to debug the undefined reference error.

STM32L4 HardFault_Handler?

Using memcpy to get data from ADC buffer to use elsewhere

Need to get specific number of samples from ADC, what flag to use to indicate when arraystoring samples is full?

Debugging in STM32CubeIDE

Using STM32F413 NUCLEO-144 development board and having issues with DAC on PA4 CH1.
