WebDMA0 triggers DMA1 to transfer a value from an array of coefficients to OP2 which completes the Multiply-Accumulate. DMA0 is set to size=1. DMA1 is set to the length of the coefficient array, "x". When "x" values have been MAC'd, DMA1 causes an interrupt which stores the result, clears the MAC result registers, and the whole thing starts over.

WebJul 5, 2024 · Part 1: Play a Musical Note on an STM32F3. To start with, let’s go over the most common type of STM32 DMA peripheral and use it to send some simple audio data to the chip’s DAC peripheral. I’ll be using an STM32F303 core for these examples; something like a ‘ Nucleo-32 ‘ board or an ‘ F3 Discovery Kit ‘ should work. WebExample. In this example 2000 bytes will be transfered using DMA, Transmit Half Complete and Transmit Complete interrupts achieving the best performance. The first half of the transmit buffer is loaded with new data by the CPU in the Transmit Half Complete interrupt callback while the second half of the buffer is being transmitted by the DMA in the …

WebIn this tutorial, we’ll discuss the ARM cortex interrupts/exceptions, and how priority works. How interrupts are generated and how the CPU switches the context to the ISR and back to the main application. And everything you need in order to configure the NVIC & EXTI correctly and write efficient interrupt service routine handlers (ISR) code.
