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 nrf52840 sdl15.0 and peripheral define a nordic card. A

    nd i want to synchronize the timer  of several  peripheral card sorry for my english 

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

    Then how are you communicating between the devices?

    thank's to ble role ( Unless I don't understand how roles work. )

    i want to synchronize just with ble protocol, without radio protocol? if it's practicable

    if I use this tutorial will the transmission be affected?

    The blog post describes how to use the SoftDevice with the Timeslot API in order to use a propriatary 2.4GHz protocol to synchronize nordic devices, whilst being able to service BLE connections. We do not have a solution for time synchronization over BLE yet, but we will with future versions of the BLE spec.
