Parallel synchronous interface (AN4666)

Discussion created by Bertrand Denis Employee on Dec 23, 2016

Wanna connect your STM32 to a parallel interface like a camera but your part does not embed a camera interface ?

Or you want to connect to a FPGA for example or other device with a non standard parallel interface ?

 

Then you should have a look at AN4666.

It provides detailed implementation using DMA and Timers while minimizing core load.

You can handle a flux up to 10 MHz with a system frequency at 80 MHz on the STM32L4.

 

Examples available on STM32F4 and STM32L4.

 

A software Cube extension is available: X-CUBE-PARAL-COM.
