GetUserID

Syntax:

Command Availability:

Available on all Microchip microcontrollers that support UserIDs.

Explanation:

Reads the memory location and returns the ID for a specific microcontroller.

If the microcontroller does not support GetUSerID then the following message will be issued during compilation Warning: GetUserID not supported by this microcontroller.

The method reads the memory location 0x8000 + Index and returns it as a Word value, where the Index 0x00 to 0x0B as follows:

Address	Function	Read	Write
8000h-8003h	User IDs	Yes	Yes
8006h/8005h	Device ID/Revision ID	Yes	No
8007h-800Bh	Configuration Words 1 through 5	Yes	No

Refer to your particular Device Datasheet to confirm the address table

Example:

      #chip 16F1455
      #Config MCLRE_ON

      #include <GetUserID.h>

      #define USART_BAUD_RATE 19200
      #define USART_TX_BLOCKING

      'Implement ANSI escaope code for serial terminal NOT using a LCD!
      #define ESC   chr(27)
      #define CLS   HSerPrint(ESC+"[2J")
      #define HOME  HSerPrint(ESC+"[H")
      #define Print HSerPrint

      CLS
      HOME

      dim UserIDRegister as word

      For Index = 0 to 0xF
        UserIDRegister  = GetUserID(Index)
        HserPrint "80" + hex(NVIndex)
        HserPrint " : "
        HserPrint hex( UserIDRegister_H )
        HserPrint hex( UserIDRegister    )
      Next Index

    End
