    Question Eusart?

    Hi just wondering how to use EUSART with picbasic pro. never used it before.
    anyone had a pop? if so, what are the differences?

    cheers

    Do you mean USART?

    USART is a built in feature in som PIC that allow serial communication without using SERIN/SEROUT function. This allow you to save a amount of code space and to use USART interrupt too. Do a search with USART or HSERIN or HSEROUT... this will give you about 2 millions of threads

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.

    hehe, yeah i no....
    i did mean EUSART. its Enhanced USART.

    this is straight off the 16f688 datasheet

    ENHANCED UNIVERSAL
    ASYNCHRONOUS RECEIVER
    TRANSMITTER (EUSART)
    The Enhanced Universal Synchronous Asynchronous
    Receiver Transmitter (EUSART) module is the serial
    I/O module available for PIC16F688 . (EUSART is also
    known as a Serial Communications Interface or SCI).
    The EUSART can be configured as a full-duplex
    asynchronous system that can communicate with
    peripheral devices, such as CRT terminals and
    personal computers. It can also be configured as a
    half-duplex synchronous system that can communicate
    with peripheral devices, such as A/D or D/A integrated
    circuits, serial EEPROMs, etc.
    The EUSART module implements additional features,
    including automatic baud rate detection and
    calibration, automatic wake-up on Break reception and
    13-bit Break character transmit. These make it ideally
    suited for use in Local Interconnect Network (LIN) bus
    systems.
    The USART can be configured in the following modes:
    • Asynchronous (full-duplex) with:
    - Auto-wake-up on Break
    - Auto baud calibration
    - 13-bit Break character transmission
    • Synchronous – Master (half-duplex) with
    selectable clock polarity
    • Synchronous – Slave (half-duplex) with selectable
    clock polarity

    cheers man
