# at89s8252-arduino This is a programmer for the Atmel AT89S8252 microcontroller through Arduino's SPI port from an intel hex file. # Installation ## Hardware Upload `progammer.ino` to your Arduino board. Connect the target microcontroller to VCC and GND, and add a crystal between XTAL1 and XTAL2. Make the following connections between the Arduino and the AT89S8252. | AT89S8252 | Arduino | |---------------|---------| | RESET (Pin 9) | Pin 9 | | MOSI (Pin 6) | Pin 11 | | MISO (Pin 7) | Pin 12 | | SCK (Pin 8) | Pin 13 | ## Software Install PySerial and IntelHex modules for Python. ``` python3 -m pip install pyserial intelhex ``` # Usage Edit `config.py` to change the serial port and target/dump hex files. In the blink directory there is `blinky.hex` that can be used as a sample program. Program the microcontroller by running the script `writeprogram.py`. * If you want erase the chip run `eraser.py` it erase both program and data space. * If you want dump the program on chip run `readprogram.py` * If you want check the chip program from a file run `verifyprogram.py` You can also write, read, and verify data space with: * writedata.py * readdata.py * verifydata.py
