Hello,I am using STM32H747 Discovery board in that I am using TFT display using LVGL in code my RAM is taking space upto 250 KB and my code is going in hardfault_handler(); Can anyone suggest me the solution
How to access the signal formation process when using DMA
A signal is generated by a DAC DMA used on the STM32F405. Using a buffer containing an array [100]. As shown in the picture, the point (circle on the line) represents the point to be detected. This is only for detection, not to start and stop the sig...
