    Default New PIC18 K83 family with CAN and Core Independent Peripherals

    The PIC18 K83 family combines an extensive array of Core Independent Peripherals (CIPs) with the PIC18 CAN product line.

    The devices include a full complement of Core Independent Peripherals including Cyclic Redundancy Check (CRC) with memory scan for ensuring the integrity of non-volatile memory; Direct Memory Access (DMA) enabling data transfers between memory and peripherals without CPU involvement; Windowed Watchdog Timer (WWDT) for triggering system resets; 12-bit Analog-to-Digital Converter with Computation (ADC2) for automating analog signal analysis for real-time system response; and Complementary Waveform Generator (CWG) for enabling high-efficiency synchronous switching for motor control.

    PIC18 K83 family description
    PIC18(L)F25/26K83 datasheet

    New PIC's are usually supported by PDS sometime after the final product is out due to changes Microchip may make.

    These will eventually be added to the compiler, but they are full of changes for the sake of changes. And there is absolutely nothing new in them! A salesman and lawyer's dream come true. LOL

    And it uses DMA for which there is very little documentation in PDS, so I will be sticking to the conventional 18F CAN Pics for the foreseeable future.

    DMA on standard 8-bit devices such as the 18F series is actually rather pointless.

    DMA is used on the PIC24 devices, and Proton24 supports the memory architecture for it. But the actual use of DMA is usually rather pointless. It's one of these "buzz words" in the real world, because processor speed these days, does not require it very much.

    Commands cannot be created for DMA because it is an interrupt mechanism and based upon peripherals, so on all languages, SFRs need to be manipulated and a lump of RAM needs to be set aside and a vector set up. That's it!

    Also, the documentation from Microchip concerning the DMA hardware is dreadful and very threadbare.
