What are you trying to do? Make a cell phone out of a PIC? ![Laughing](images/smiles/icon_lol.gif) |

This works with Kyocera and Motorola. I haven't tried anything else. |

TDMA is Time Division Multiple Access. It is how digital wireless phones communicate. |

Yes, i know, i have a receive transmit module connected to a Pic 18lf6720. I want to implement a tdma protocole in the pic. Do you have informations about the methode (code, algo...)?
Thanks a lot. |

No infos about tdma with the module. The is the physic layer and tdma is on the upper layer. |
