For an STM32H747i-DISCO board (800x480 lcd), I have used TouchGFX Designer v4.22.1 to create a very simple project with a box and static graph. The white box was maximized to the full screen. The static graph was untouched.I imported this project int...

I'm using an STM32H747i-DISCO board with CubeIDE v1.13.2.My first clue that the ARM DSP library wasn't loaded was when the #include "arm_math.h" file wasn't found. It is not in any of this project's folders. I did manually copy the file into the proj...

I have created several projects in TouchGFX Designer v4.22.1 - each with a unique 'Application Name'. I'm using the STM32H747i-DISCO boards (dual-core MCU). When I import any of these into CubeIDE v1.13.2, they always show up with this type of struct...

It was difficult to learn how clone an existing project for a dual-core STM32H747i-DISCO board. Here are the steps that I used (after much researching and trials and errors):1) Copy the existing project folder called 'OLD' into a new folder called 'N...

When transmitting with a UART on this H747 board, a sent string will only get through two characters before HAL_UART_Transmit() hangs. No matter how I format the string (e.g., with or without snprintf() ), this same behavior occurs for UART8 and UART...

EDIT -- It turns out that TouchGFX Designer allow for the "Number of Data Points" to be arbitrarily changed at design time. There's no need for the 8 graphs described below. I just completely missed this when I was adding the original graph.- - - - -...

@JTP1 , that's the answer. I didn't occur to me that there was simply a limit in the number of data points that could be added.My project is for an audio spectrum analyzer that has an array of 1024 frequency bins. There are only 800 horizontal pixels...

@JTP1 , I added segmentCounter=0 before the loop starts. I also made it so the data is added to the graph only once, and I verified this by moving the led toggle to inside the loop (it now only turns on and never turns off). Neither of these changes ...

I was able to add the 'libarm_cortexM7lfsp_math.a' library per this post:Configuring DSP libraries on STM32CubeIDE - STMicroelectronics CommunityIt would be nice if CubeIDE would allow for adding the FFT and other DSP functions easily. I'm surprised ...

Yes, @Piranha. I agree with you - especially when it's broken. It's nice to have the source code. Hopefully it's not broken, too. Thanks.
