ARM, RISC-V контроллеры

Ага, вот к например SGPIO: Serial GPIO (SGPIO) = GPIO + Timer/Shift Register: – Used to create or captures multiple real time serial data streams. – No more having to write code loops to manipulate GPIO in real time. – Say goodbye to CPU intensive big banging! SGPIO = Proprietary Serial Interface SGPIO can be used to emulate proprietary serial interfaces • Problem: Lots of peripherals on the market use non-standard serial interfaces (LCD drivers, audio codec etc). • Standard Microcontroller Solution (no SGPIO): • Application designer has to write CPU intensive loops to create required bit streams – painful bit banging! • CPU is 100% occupied while waveform(s) are generated. • LPC4300 based Solution: • Configure SGPIO to generate desired waveform(s) with just a few register writes. • Interrupt generated when data is clocked out – CPU is not blocked.
