Hello everybody,

My question seems very simple but I would like a definitive answer :

Is it possible to group all ports of STM32F407xx and write one data for the new big port?

I explain me :

I would like to group all ports (A -> I) and write a data of 140 bits. The 16 first bits are written in the port A ... and the 12 last are written in the port I.

I don't want to write port by port because it's too long (around 300kHz). I want around 1 MHz and I think it is the only solution.

Thanks in advance for your answers or suggestions !

Florian
