DMA，全称Direct Memory Access，即直接存储器访问。 DMA传输将数据从一个地址空间复制到另一个地址空间，提供在外设和存储器之间或者存储器和存储器之间的高速数据传输。 我们知道CPU有转移数据、计算、控制程序转移等很多功能，系统运作的核心就是CPU， CPU无 ...

STMicroelectronics has put plenty of analogue features and DMA (direct memory access) into its latest 8bit 8pin microcontroller. Dubbed STM8L050, alongside two comparators, it has four-channel 12bit ...

Analog 8-bit microcontrollers are common, but their number approaches zero as the sample rate and resolution grow. Silicon Laboratories' C8051F064 sits at the top of the heap with an 8051-based MCU ...

While regular Hackaday readers already know how to blink a LED with a microcontroller and have moved onto slightly more challenging projects such as solving the Navier-Stokes equations in 6502 ...
