DMA (Direct Memory Access) frees the CPU from these menial tasks. With DMA, peripheral devices do not have to ask the CPU to fetch some data for them, but can do it themselves. Unfortunately ...

Direct memory access (DMA) is a means of having a peripheral device control a processor’s memory bus directly. DMA permits the peripheral, such as a UART, to transfer data directly to or from memory ...

Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, has a built-in led – the green one on the left in the photo. And it has a pair of yellow leds – called TX ...

Each such chip includes a processor, memory and supporting components that allow it to perform simple computing tasks without external assistance. Arduino’s chips are used by hobbyists to build ...

Last time, in Part 1, we introduced somebasics behind Direct Memory Access (DMA) -why it's needed, and how it's structured and controlled. This time,we'll focus on the classifications of DMA transfers ...
