X-CUBE-PARAL-COM：Parallel Synchronous Transmission using GPIO and DMA software expansion for STM32Cube (AN4666)
The STM32 microcontrollers are able to emulate parallel synchronous communication through GPIOs using the embedded DMA IP.
The X-CUBE-PARAL-COM software solution developed on STM32Cube offers an implementation of such parallel synchronous interface on STM32L476G and STM32F429I discovery boards. It can easily be ported on other platforms.
