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
