Arduino Kode hjælp (nRF24l01)

[Danni-Hansen]

Hej DEF.

Har fået leget lidt med Earnst her på det sidste, og det er på tide at udvide hans 'funktioner'

Jeg arbejder lidt på at min Afstands sensor skal fortælle ham hvad han skal gøre det næste stykke tid.

Her under ser i modtager koden til Earnst som det ser ud nu (Med hjælp fra Gerd)

Jeg ville så gerne have både min sender og modtager (på Earnst) til at modtage strings via nRF24l01 signalet.

Så fandt disse 2 koder:

Den her til at sende strings:
https://gist.githubusercontent.com/shnae/8642916/raw/nrf24l01_send_string

De her til at modtage strings:
https://gist.githubusercontent.com/shnae/8642903/raw/nrf24l01_receive_string

Problemet er mest at jeg aner faktisk ikke hvordan jeg umidelbart skal sætte modtager ind i min nuværende kode.

Det er jo min pc der skal tage beslutningerne, udfra hvad afstanden er, så det eneste Earnst egentligt skal, er at tage imod det han får afvide, også levere en afstand i cm. (Push/Pull)

Nogen der kan hjælpe?

Mvh. Danni.

Har bikset den her kode sammen (Til Earnst):
