Titel:  Re: P1 poort uitlezen (hardware)

Ik heb toevallig dit weekend mijn slimme meter aangesloten op mijn Nodo. Ik heb gewoon het schema gebruikt wat op de WIKI bij plugin 24 staat.

Dus uit mijn hoofd de Wired-out 1 (pin 30 op de Mega?) aansluiten op de RTS van de P1 poort. Dit zelfde ook op de voeding van je inverter (7414 chipje bijvoorbeeld).
De Ground van de Arduino sluit je aan op de GND van je inverter en op de ground van je P1 poort.
Het enige dat je dan nog hoeft te doen is de data uit je P1 poort verbinden met de ingang van één van de inverters die in de 7414 zit en de uitgang van die zelfde inverter naar de RX pin van je Arduino verbinden.

Eigenlijk precies zoals het in het schema staat :-)

Het enige dat mij in verwarring bracht is de kleuren in een telefoonsnoertje. Bij mij was het rode draadje de Ground en het zwarte draadje de RTS. Even verwarrend, maar het klopte wel. Je kunt gewoon de pinnetjes tellen en wederom het schema van de WIKI gebruiken. Ik heb niets met LEDjes gedaan.

Kun je iets specifieker zijn in wat je niet begrijpt aan dat schema?

Hallo Sjoerdp,

Bedankt voor je reactie.
Ik ga de onderdelen bestellen en er mee stoeien.

Ik ben er uit en ga een Mini Pro gebruiken voor het uitlezen van mijn Energie meter.
deze zal eerst via !2C met mijn master (mega nodo) gaan communiceren.
Later zal dat met NRF gaan gebeuren. (de chinees is helaas niet zo snel deze keer)

Ik zit alleen nog met het aansluiten op de Mini Pro
Ik heb nu het volgende bedacht

Klopt dit of moet ik de TXO en RXI omdraaien?
