about PPI

[lmouelo]

I studied the ppi register but I have some questions?

Can we synchronize more than 2 peripherals?
Fork registers can trigger a second task from a task simultaneously? and if so
can this second stain be applied to another peripheral?

thank's

You can connect any peripherals EVENTs to any peripheral's TASK with the exception of the radio where it will break the SoftDevice if its running. This means that you can create whole state machines with just peripherals and PPI.

Have fun exploring what you can do with it and tell us if you figure out something cool :P

it's really possible to do this with ppi register ?

I believe this is what you want:

i want this but can i synchronyze the diferent timer, of the diferents nordic card, without using the RADIO role.

Then how are you communicating between the devices?
