Posted on March 24, 2017 at 19:00STM32F437I am using TIM4 channel 1 and would like to have the timer output handled by DMA instead of my timer ISR but my DMA attempt is not working. So I am fishing for timer/dma example code hopefully that uses DMA ...

DMA2D Rotation

Posted on March 24, 2017 at 20:03Hi,The DMA2D peripheral is great, and I'm using with no issues.  I was wondering if it's possible to rotate an image 90 degrees using this peripheral.  Has anyone done this?Thanks!Bobby

Resolved! STM32F446 DMA Indexing

Posted on March 22, 2017 at 22:54I ultimately need 'instant on' ADC conversions.  For instance, when a timing gate goes high, I need to start taking ADC values immediately (the signal is only 100us wide),  The problem I'm running into is the lag: fi...
