unziplib's Introduction

unzipLIB

What is it?

An 'embedded-friendly' (aka Arduino) library to extract and decompress files from ZIP archives

Why did you write it?

I wanted to be able to unzip files on MCUs for various projects and I couldn't find any libraries that would do the job. The thing that prevents most Linux open source projects from running on embedded boards is their use of the file system and heap management. There is support for malloc/free on Arduino, but it's better to control how memory is used more directly (e.g. TCM vs FLASH vs DDR).

What's special about it?

I designed the unzip library to not rely on malloc/free, but instead to have a fixed class/structure which could be managed by the user. I also removed the dependency on the file system and instead offer a set of callback hooks to allow zip files to be read from memory, SDCard or any media. These two features give it maximum flexibility to run on low end systems.

Feature summary:

Runs on any MCU with at least 41K of free RAM
No external dependencies (including malloc/free, file system calls)
unzip API implemented in C and C++
ZIP files can come from RAM, FLASH, SDCard or any media by using callbacks
Decompress files by reading any sized chunk at a time (full sized buffer not needed)
Compiles on any target CPU

Detailed information about the API is in the Wiki

unziplib's Issues

must use RAM 41K，can not save some？

maybe can 32K to 16K？

change MAX_WBITS or other。。

Chunk by chunk read

Hi,

I'm still not able to read the unzipped data chunk by chunk.
If I would read it at once, It would not fit into RAM. My unzipped data size is 393 KB
If I comment out Block 2, it is working, but I would like to read 512 bytes one after another:

...
#define BUFF_SIZE 512
static uint8_t l_Buff[BUFF_SIZE];
...
    // Block 1
    zip.openCurrentFile();
    mySeek(&myfile, 0, SEEK_SET);
    int readSize = zip.readCurrentFile(l_Buff, BUFF_SIZE);
    Serial.print("Bytes read in buffer: "); Serial.println(readSize);
    binFile.write(l_Buff, BUFF_SIZE);

    // Block 2
    mySeek(&myfile, 512, SEEK_SET);
    readSize = zip.readCurrentFile(l_Buff, BUFF_SIZE);
    Serial.print("Bytes read in buffer: "); Serial.println(readSize);
    binFile.write(l_Buff, BUFF_SIZE);

ESP32

Good day. Please give an example of unzip to esp32 from SPIFFS. Thank you.

can't get my png

Hi,

thanks for sharing your library

I am testing your example on ESP32 to get pgn on my SD card
I found a little mistake in your code at line 85 : rc = rc = zip.openZIP(name, myOpen, myClose, myRead, mySeek);
I think it should be rc = zip.openZIP(name, myOpen, myClose, myRead, mySeek);
Right ?

Now I place a chitubox zip at root on the SD card (I check there is PNG there inside)
the serial give me

File: Carriage.ZIP
[869141][E][vfs_api.cpp:29] open(): Carriage.ZIP does not start with /

this error message seem to come from library, can you help to solve the pb ?

Kind regards

Chunkwise write the uncompressed file.

Hi,

I could create a simple program to test your library with SdFat library, instead of standard Arduino SD.
But I realized, that I still have a problem.
I would like to implement FOTA, so I will download the application.zip file.
Then I want to unzip it (application.bin).
The .bin file is quite large (393216 byte). I don't have this much memory. (I have 56+4 KB of SRAM on STM32F429ZI).

So my question, how can I use your library, so that I can write this larga application.bin to the SD card in chunkwise manner?

Here is my code:

#include <Arduino.h>
#include <unzipLIB.h>
#include "SdFat.h"
#include "sdios.h"

SPIClass SPI_4(PE6, PE5, PE2); // MOSI, MISO. SCLK
const uint8_t SD_CS_PIN = PE4;
#define SD_CONFIG SdSpiConfig(SD_CS_PIN, DEDICATED_SPI, SD_SCK_MHZ(4), &SPI_4)

UNZIP zip; // statically allocate the UNZIP structure (41K)
SdFat sd;
File root;
static File myfile;
static File myfileAnother;

void * myOpen(const char *filename, int32_t *size) {
  root.open("/");
  myfileAnother.open(filename);
  *size = (uint32_t)myfileAnother.fileSize();
  return (void *)&myfileAnother;
}

void myClose(void *p) {
  ZIPFILE *pzf = (ZIPFILE *)p;
  File *f = (File *)pzf->fHandle;
  if (f) f->close();
}

int32_t myRead(void *p, uint8_t *buffer, int32_t length) {
  ZIPFILE *pzf = (ZIPFILE *)p;
  File *f = (File *)pzf->fHandle;
  return f->read(buffer, length);
}

int32_t mySeek(void *p, int32_t position, int iType) {
  ZIPFILE *pzf = (ZIPFILE *)p;
  File *f = (File *)pzf->fHandle;
  if (iType == SEEK_SET)
    return f->seek(position);
  else if (iType == SEEK_END) {
    return f->seek(position + pzf->iSize); 
  } else { // SEEK_CUR
    long l = f->position();
    return f->seek(l + position);
  }
}

void setup() {
  Serial.begin(115200);

  while (!Serial && millis() < 3000);
  Serial.println("Search for ZIP files on the SD card");
  
  if (!sd.begin(SD_CONFIG))
  {
    sd.initErrorHalt(&Serial);
    Serial.println("Unable to access SD Card");
  }

  if (!root.open("/"))
  {
    Serial.println("Open root failed");
  }
  //////////////////////////////////////////////////////////////////////////////
  int rc;
  char szComment[256], szName[256];
  unz_file_info fi;

  const char *name = "application.zip";
  if (!myfile.open(name, O_RDONLY))
  {
    Serial.println("Opening application.zip failed");
  }
  Serial.println("Openend application.zip");
  rc = rc = zip.openZIP(name, myOpen, myClose, myRead, mySeek);
  if (rc == UNZ_OK) {
    Serial.print("ZIP file found");

    // Display the global comment and all of the filenames within
    rc = zip.getGlobalComment(szComment, sizeof(szComment));
    Serial.print("Files in this archive: ");
    zip.gotoFirstFile();
    rc = UNZ_OK;
    rc = zip.getFileInfo(&fi, szName, sizeof(szName), NULL, 0, szComment, sizeof(szComment));

    if (rc == UNZ_OK) {
      Serial.println(szName);
      Serial.print("Compressed size: "); Serial.println(fi.compressed_size, DEC);
      Serial.print("Uncompressed size: "); Serial.println(fi.uncompressed_size, DEC);
      
    }
    zip.closeZIP();
  }
}

how to unzip and LCDdisplay the included PNG files ?

Hi,

Thanks a lot to share those nice library

I already use PNGdec for some firmware running on ESP32
Now I would like to extract PGN from a ZIP located on my SD cardand send this on LCD

I start with you nice sample code but done for BMP image
I try to change and add PNGdec but I cannot succeed to extract image

I saw you do extract image here
icBitmap = (uint8_t *)malloc(fi.uncompressed_size); // allocate enough to hold the bitmap

But how to pass this to PNGdec ?
As using filemane give me dimension and other things but cannot decode and display

Kind regards

SdFat example

Hello,
I would have a question.
Do you have some example code for SdFat library (https://github.com/greiman/SdFat)?
I would like to use your library, but on STM32, I can't use the standard SD library.

conflicting with other

Hi,

I have tested the SD example that works good
But porting the library in my sketch ( just #include <unzipLIB.h>) bring compilation error :
