How Can I insert pic ID on code

Hello All
I want to write ID for pic id address on IDE (like a config or edata)
how can I do it?

thanks a lot
Ahmet

Ahmet -

Sorry, but it's not clear to me what you want. Are you looking for code to read the chip IDLOC area?

That's a bit very vague. I'm willing to bet you've not been programming long--spend enough time programming and it becomes ingrained that imprecision and ambiguity are bad.

Now then, I'm guessing you're asking how to use the EEPROM.

Code: Select all

Include "EEPROM.bas"
//--- --- --- --- --- --- --- --- --- --- --- --- --- --- --- 
// EEPROM Value                                'Address
EEPROM = (%11100110 As Byte)    'ConfigByte1,   '0
EEPROM = (%00110000 As Byte)    'ConfigByte2,   '1
EEPROM = (%00000000 As Byte)    'ConfigByte3,   '2
EEPROM = (65535 As Word)        'Number   '3 - 4
EEPROM = (52 As Byte)           'ID     '5

Const 
  ConfigByte1_EEPROM = 0
Dim
  ConfigByte1 as Byte

  ConfigByte1 = EE.ReadByte(ConfigByte1_EEPROM)

  EE.WriteByte(ConfigByte1_EEPROM, ConfigByte1)

There's a little do-nothing example code which should point you in the correct direction.

Good luck, happy coding.

Isn't he talking about the chip ID word that you can program for the pic?
If I wanted to program that ID, I would do that separately in MPLAB rather than in the program code.

Like the config bits, e.g. Brown-out, code protect, ... I.D.

Actually, no I changed my mind. It would be way better to do it in the program code. I've never used the chip ID yet, but I can think of many uses for it. But then what ever ID it is that you want to burn to the chip, you could easily just put it in the EEPROM. Make it something cool like the last byte in the EEPROM memory or something.

thanks for attention senacharim

FYI, Yes you can do it in MPLAB Configure>ID Memory but that will only give you access to the lower nibble of the user ID, The high nibble can be only be written to via program code.

Thanks to Jerry he has put together a small userID Module which you can download in the USB Library.
