Plenty of analogue, and DMA, in 8pin 8bit STM8 MCU

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 ...

DMA controller

Like just about everyone we know, [Luis] decided a gigantic RGB LED matrix would be a cool thing to build. Gigantic LED matrices are very hard to build, though: not only do you have to deal with large ...

Microcontroller interfaces ARM7 core with FPGA

Atmel’s ARM7-based AT91CAP7E microcontroller includes an FPGA interface, a six-layer AHB (advanced high-speed bus), a peripheral-DMA controller, and 160 kbytes of on-chip SRAM. The FPGA interface ...

DMA Lets 8051 MCU Handle Dual 16-Bit, 1-Msample ADCs

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 ...
