Is there a template or a sample application that one can use to develop fast running waveform display feature in TouchGFX? (such as that of a oscilloscope waveform display and not a static or slow speed 1-dim graph display)if not any suggestions? ..t...

Posted on January 23, 2014 at 18:40Hi, All EXTI-External interrupts on STM32Fxx and other STM32 devices implemented by STM are EDGE triggered interrupts. The ARM core however supports Level, Pulse and Edge triggered interrupts. STM32Fxx Tech.Ref.M...

may be the data register of the DFSDM filter should be the Source address :

Thanks for the update. Here's what I wanted to do :I want to use the DFSDM peripheral in multibufferDMA mode.Currently it works ok in circular buffer mode (based on the STM's example use) but it's not what I want.There are few HAL multibuffer driver ...

Appreciate your quick and always valuable answers and feedback.Descriptor based cyclic multibuffer use is quite a common scenario in high speed data captures be it audio, video etc. I use it all the time in many DSP and FPGA architectures (with ARM ...

Yes, that's the ultimate step to get things to work in the absence of tools support..but it requires long..many days if not weeks long..efforts..

I'm trying to use the MultibufferDMA mode of HAL driver for STM32F769 device. There's not a single example I could find which uses this mode in the list all the applications/demos/examples for STM32 devices. Here's an example call I use :

STM32CubeMX for F7 etc devices does not support Multibuffer DMA modes for DFSDM peripherals. This feature is needed for many applications. HAL driver has this but is not useful for DFSDM. Any one has ideas how to use this with DFSDM?

Is high speed waveform display feature possible in TouchGFX?
