Hello:I am looking for a fast way to add an array of data to a static graph without adding them one point at a time using addDataPoint(). I also don't care about the x values. They are just sequential. I want to update the entire graph at once and th...

I am using a touch controller with TouchGFX on a custom board. It is using I2C1 on the MCU and is working fine with TouchGFX. However, when MX_TouchGFX_Init() runs it is reconfiguring pins on the MCU for I2C2 that I am using for other functions. I2C2...

Hello,I followed the STMicro YouTube tutorial for developing an external QSPI loader. I am using the W25Q128 attached to the NUCLEO-H7A3ZI-Q. The flash is working fine with my driver using the test program "main_test.c" provided with the tutorial, an...

I wanted to thank everyone for their help. It turned out to be a stupid mistake. I had the external flash address entered correctly in ST-Link Utility but was missing a zero in the address in STM32CubeProgrammer. Stupid mistake. It works fine with t...

I was wondering if there is a way to get a more detailed log file from STM32CubeProgrammer. Even at L3, I don't see any details about the external loader functions being called ( register preloads ) and the results or errors.Trial and error is not ge...

Hi Tesla,Thanks for the advice. I made sure that all addresses were masked to my external flash size. The Init and Verify functions place the OSPI into memory-mapped mode. Write, SectorErase, and MassErase, disable memory-mapped mode using HAL_OSPI_D...

Fast method to add data to a static graph

MX_TouchGFX_Init configuring wrong I2C touchscreen pins on MCU

External QSPI Loader data read failed message

I am unable to download the template for the STM32H7B3I-DK.

Are there plans to add audio playback support to the video widget in TouchGFX? All of the examples show audio being stripped off when generating the MJPEG AVI file with ffmpeg.
