Raspberry Pi Forums

Hi together,

I'm a real newbie in program bare metal Code on a armv8 CPU in assembler. At the moment I want write a "nearly" real time program on the Raspberry Pi 3 and I need for this intend a list with the GPIO address from this Chip. Now I can't find the a documentation with this Information, thats the reason why i would ask you i've somebody knows where I can find a GPIO documentation?

Thanks for your answers!

There is a sticky with all the links which always remains the second post down on this forum.

Anyhow

The errata (AKA typo and errors on the sheet)

The physicals of the port

Word of warning just because you are talking about "real time" the peripheral IO speed is restricted to 68Mhz on a Pi3, 48Mhz on a Pi2 and 22Mhz on a Pi1 by the slow peripheral exchange bus. If you expect speeds up near the CPU speed it isn't going to happen.

Ohh... sorry i used just the searching Method to find the information in the Forum - sometimes is the solution more near than we think

Thanks you for the information and the support
