Proteksi firmware ATmega dengan Nomor Seri

LH

Menggunakan bantuan 1-Wire device, dengan jenis yang bermacam macam, misal: DS1820

#include <OneWire.h>
#include <EEPROM.h>

#define DEBUG 1

bool validity = false;
void setup(void) {

#ifdef DEBUG
  Serial.begin(9600);
#endif

  validity = getDeviceAddress();
}

bool getDeviceAddress(void) {
  byte i;
  byte addr[8];
  bool valid = false;

  unsigned long upper = 0;
  unsigned long lower = 0;

#ifdef DEBUG
  Serial.println("Getting serial number...\n\r");
#endif
  while (ds.search(addr)) {
    if ( OneWire::crc8( addr, 7) != addr[7]) {
#ifdef DEBUG
      Serial.print("CRC is not valid!\n");
#endif
      return;
    }

    for (byte i = 0; i < 4; i++) {

Mengubah USB ISP menjadi USBASP

LH

USBISP berbeda dengan USBASP. USBISP tidak dapat dioperasikan dengan AVRDude, namun harus menggunakan PROG ISP. USB ISP menggunakan uC ATmega88, dengan skema mirim USBASP namun bedanya adalah pin D- pada USB dihubungkan ke PD3, jadi PD3 harus diubah menjadi pin INPUT.

Agar dapat berfungsi jadi USBASP, maka download firmware dari https://www.fischl.de/usbasp/usbasp.2011-05-28.tar.gz dan ekstrak.

Buka file bin/usbasp.atmega88.2011-05-28.hex menggunakan notepad++ atau wordpad.

Lihat pada baris 100B8000,

:100B8000D9F77A9589F708951BB815B88BEF8AB90C

ubah menjadi :

:100B8000D9F77A9589F708951BB815B880EF8AB917

ubah ldi pada DDRD 8BEF menjadi  80EF

dan ubah checksum dari  0C  menjadi  17

Buka kemasan USBISP dan hubungkan via (lubang) yang ditandai <– UP –> menggunakan kabel kecil.

Upload dengan USBASP atau Arduino yang telah dijadikan Arduino as ISP.

Note:

# TARGET=atmega8 HFUSE=0xc9 LFUSE=0xef
# TARGET=atmega48 HFUSE=0xdd LFUSE=0xff
# TARGET=atmega88 HFUSE=0xdd LFUSE=0xff

gunakan HEX berikut, jika uC yang digunakan adalah ATmega8:

Menambahkan Bootloader ATMega8 di Arduino versi 1.5.x ke atas

LH

buka file platforms.txt

cari bagian: tools.avrdude

copy paste barisnya dan ubah menjadi tools.avrdudeM8 dengan menghapus -Uefuse:w:{bootloader.extended_fuses}:m

# AVR Uploader/Programmers tools M8

Buka Board.txt, cari atmegang.menu.cpu.atmega8=ATmega8 dan tambahkan diatasnya:

 

atmegang.menu.cpu.atmega8.bootloader.tool=avrdudeM8

Selanjutnya pilih Board: ArduinoNG, Processor: ATmega8, Programmer: (sesuaikan)

Siap untuk klik, Burn Bootloader

Mengubah script python menjadi executable

LH

Menggunakan Linux

Gunakan pyinstaller, pasang dengan:

pip install pyinstaller

Jika gagal, maka:

Buka: https://github.com/pyinstaller/pyinstaller/releases
Download: PyInstaller-3.3.1.tar.gz lalu extract dan masuk kedirektori tersebut.
Eksekusi dengan perintah:

sudo python setup.py build 
sudo python setup.py install

Selanjutnya ubah script python ke executable dengan

pyinstaller --onefile <script_phyton>.py

Jika dikatakan bootloader belum tersedia, misalnya untuk Linux ARM 32Bbit, maka harus dibuat dahulu. Pada hasil download PyInstaller ada direktori bootloader. Masuk ke direktori tersebut dan jalankan perintah:

sudo python ./waf all
cd ../PyInstaller/bootloader
cp -R Linux-32bit-arm/ /home/pi/.local/lib/python2.7/site-packages/PyInstaller/bootloader/Linux-32bit-arm/
