What is DMA2D? With the advancement of embedded graphics, microcontrollers are taking on increasingly complex graphic computation and display tasks. However, the CPU’s processing power may not suffice for handling high-resolution and vibrant-color graphics. Fortunately, starting from the STM32F429, an external peripheral akin to a GPU has been introduced into STM32 microcontrollers by ST, known
Programming and debugging with simulators can be a great way to get started with the SAMD21 microcontroller. It provides a great platform for those who are new to embedded systems and want to get a better understanding of how they work. By utilizing a variety of simulators, it is possible to develop projects and applications
