I was able to successfully install and launch CubeMX. However, I cannot download the packages. In my case I need the STM32CubeG0 firmware packages. When I download it manually and select "From Local" I get "Failed to create temporary directory". In ~...

I have a problem with a hardfault in my system that I cannot resolve. The problem occurred while operating the display. When I change the transparency value, hardfaults suddenly occur (BSP_LCD_SetTransparency). But elsewhere in the program.Now I have...

I'm experimenting with the LCD library on the STM32F746G-DISCO board. I wanted to display an image from a BMP file on the display. Unfortunately this never worked. I looked at several examples, and finally noticed that the function LL_ConvertLineToAR...

I am using a STM32 Discovery Board with external SD Ram. I used the memory in RAM so far by creating a Ponter in the SD-Ram address area.But now my program is getting more and more complex and I could use a memory manager. Can I use the Malloc, Callo...

I have a 32F746GDISCOVERY and would like to test the dsp functionalities with a correlation.I have the following code:#include "arm_math.h" extern void arm_correlate_fast_q31(q31_t * pSrcA, uint32_t srcALen, q31_t * pSrcB, uint32_t srcBLen, q31_t * p...

Thank you so much for this short version. In fact, she helped me, although I still don't know exactly where the problem lies. Definitely but on the display. As soon as I deactivate the display, everything works. Unfortunately I don't have the time to...

Thanks for your answer. So you think it's a problem of decoding? I don't suppose the problem is there. I tried to do the same with images from examples online as well as with self-generated ones. The result was always the same. I didn't see anything....

There's a lot that's new to me. I use the GCC. I was looking for "syscalls" or "_sbrk" in my project. I only found a few files from the µOS++ distribution which are not used. How do I get on with the problem? What do I have to search for?

I thought if PLLN=400 is a multiplier that generates the 216MHz, then 380 => 216/400*380 = 205 MHz should be generated. A bit closer at 200MHz might be more precise expressed. At least it's working now. Even if I don't understand exactly what I chang...

As in many examples I found online the clocks are configured with a function void SystemClock_Config(void). To make the display work, I copied the function from an example. It caused the error in the SD-Ram write process. As I read from the comments,...
