ATMEL	AT90S1200, AT90S1200A, AT90S2313, AT90S2323, AT90S2343, AT90S4433, AT90S8515, AT90S8535, ATtiny12, ATtiny15, ATtiny2313, ATtiny26

Note:

• The configuration word in HEX file is written.
• The EEPROM data in HEX file is written.
• High Voltage method for PIC writing
• Low Voltage serial method for ATMEL
• PICer automatically verify to make sure programmed.

(3)Installation

1. Download the driver software port95nt.exe and excute it. You need reboot.
   The default installation directory will be C:\Windows\Program Files\DLPortIO.
   
2. Download PICer, melt it with Winzip and copy PICer.exe.
   

To unistall, select DriverLINX Port I/O Driver from "add or delete program" on "control panel".

(4)Usage

1. To excute, double click "PICer.exe".
2. Select PIC type to write.
3. Select LPT to use.
4. Erase button: erasing program
   If PIC chip has factory OSC calibration data, PICer keep it.
5. Check button: checking blank
6. Program button: writing program
   PICer check to connect the circuit when you push the button. If no connection, you will see a error message "Error: Not ready LPT port!". Check the circuit and select proper LPT port.
   When PICer detect the circuit, you will see popup file open window. You can select a HEX file.
   PICer automatically detect HEX format. Supported format is INHX32, INHEX16 and INHX8M.
   

Note: turn off the writer circuit when you set PIC.

Special note for ATMEL

• .eep file has data area of ATMEL. Put it on same directory .hex file.
• .hex file doesn't have FUSE of ATMEL. Make .cfg file to set FUSE with notepad tool. See sample.cfg file.
  Example test.cfg:

  	LOCK=3
  	RCEN=0
  

• The head semicolon is comment.
• Each line has a LOCK or a FUSE.
• You can write LOCK and FUSE in lines without order.
• You can erase LOCK in ATMEL.
• You can't erase FUSE in ATMEL.
• Caution!: Do NOT set RSTDISBL=0, PICer will not able to re-write.
• Caution!: Do NOT set PLLCK=0, PICer will not able to re-write.
• PICer(Low Voltage serial method) can't change SPIEN.
