Hi,Not a question, but a bug report.Setup:TouchGFX 4.21.1Simulation on VS2022It seems that the internal variable holding the histogram bar position is not updated when the bar width is changed at execution time.Example:1- The bar width is set to 100 ...

Hi,Scaling down an histogram graph to display only one bar triggers a "(min != max)" error.I need to display from 1 to 16 bars on my histogram.I use the setGraphRangeX(int min, int max) function for this.However, when I get down to 1 bar with setGrap...

Hi,I noticed that there is a touchgfx::memset implemented in Utils.hpp.Any reason to use touchgfx::memset over the one from string.h?Thanks.

Hi,I am migrating some code from an STM32F745 to an STM32H743.I came into some trouble while using the crypto library and the hardware CRC at the same time.The STM32H743 crypto library resets the CRC DR register every time AES_CBC_Decrypt_Append is c...

Hi @Yoann KLEIN ,I was building the small demo when I realized that the issue is not what I thought.It's not that there is a problem with the X position of the bar not being internally updated.The problem is that the function Graph.indexToScreenX() ...

Hi Junde,First of all, did you manage to display your red square?Your SDRAM is going to be accessed by both the LTDC and TouchGFx at the same time.The LTDC reads data from the SDRAM while TouchGFx writes data to it.If there are a lot of things changi...

I'll find some time to make a small demo and I'll share it here.Thanks.

Hi,I am using the same LCD controller.I think you made a mistake on your LTDC setting.Horizontal Synch Width: 1pxVertical Synch Height: 1 lineYour other LTDC settings are the same as mine.Just be aware that with a 1024x600 screen, you are at the limi...

Yes, nice trick!It does work using float parameters.I used setGraphRangeX(0.0f, 0.0001f + Range) instead of 0.5f + Range as the 0.5f adds some margin on the right when the range is set to the maximum.BTW, I think I found another where the bar positio...
