Programming
First, Install Atmel’s FLIP software on your PC and open the software.
- Select the appropriate device in the device selection menu. (For AT89LP51xx2 series devices, please select the corresponding device from AT89C51xx2 series. For example, In order to program AT89LP51RD2, you have to choose AT89C51RD2. Because both of them have same UART based boot loader)
- On your board, press RESET switch (I hope you have a RESET switch on your board) and PSEN switch together.
- Now release the RESET switch first and then release the PSEN switch.
- Now in the FLIP software, select the communication medium as 'RS232' and select the appropriate port and baud rate.
- Now you should be able to program the ‘hex file (.hex)’ into the device through FLIP software.
