60Hz Static graph rendering

[PJD]

Hi, I'm trying to render a 60Hz waveform using a static or dynamic graph widget. The use-case is to render all 480 points at a 60Hz rate, e.g., a noisy sin wave... My graph is size 240x480 pixels using 480 data points. I'm trying to demo this on 2 Eval boards, STM32U5G9J-DK2 and STM32H747I-DISCO. I cannot achieve the required 60Hz refresh using 240x480 graph size, however, using a much small graph I'm able to get 60Hz refresh.

My Question: is it possible to achieve the 240x480 draw at 60Hz using the above gpu hardware or is there a more capable STM32 hardware solution or software solution. Thanks...

Hello @PJD,

Unfortunately, graphs are computationally expensive widgets. As you mentioned, reducing the size of the graph or the number of data points can help increasing the computation. 

Also, you can try developing on STM32H7S7 which contains a powerful MCU. 

If you need more help or specific support, I can direct you to an individual supporter.
