IMSProg - I2C, MicroWire and SPI EEPROM/Flash chip Programmer - is a program to read, write EEPROM chips use the CH341A programmer device.

The IMSProg makes respect to QHexEdit2 hex editor and SNANDer programmer. The chip database format is clone with EZP2019, EZP2020, EZP2023, Minpro I, XP866+ programmers. You can edit the database use the EZP Chip data Editor

IMSProg is a collection of tools:

IMSProg - the chip programmer (it's the main part).
IMSProg_editor - chip database editor.
IMSProg_database_update - script to update chip database using external web-server.

Compiling programmer

git clone https://github.com/bigbigmdm/IMSProg.git && cd IMSProg
cd IMSProg_programmer
mkdir build
cd build
cmake ..
make -j`nproc`
sudo make install

ℹ️ Debian < 11 and Ubuntu < 20.04 are not supported, you may unable to have it working on them.

How to use:

Chip programmer

Connecting

Insert the chip into the appropriate slot of the CH341A programmer. The 24xxx and 25xxx series chips must be inserted directly, according to the markings on the PCB of the CH341A programmer. The 93xxx series chips must be inserted into the 93xxx adapter and the adapter into the marking 25xxx programmer slot.

If the chip supply voltage is 1.8 volt he must be inserted in 1.8 volt adapter and the adapter into needed programmer slot.

Plug the CH341A programmer into the USB socket of your computer and running the IMSProg.
You can plug and unplug the programmer device (CH341A) to the USB port at any time when basic operations (reading, checking, and programming) are not in progress.

Chip type selecting

Select the type of chip used from the Type pop-up menu: SPI FLASH when using SPI NOR FLASH chips of the 25xxx series, 24_EEPROM when using I2C EEPROM of the 24xxx series, 93_EEPROM when using MicroWire EEPROM of the 93xxx series. When using 25xxx series SPI NOR FLASH chips (Menu item type -> SPI_FLASH), the Detect button will be available. When the Detect button or or <Ctrl+D> is pressed, the JEDEC information is read from the chip and all parameters of that chip are loaded from the chip database. Any parameter (size, page size, block size, VCC voltage, and 4-bit address length) can be changed manually. You can manually enter the Manufacture and Name pop-up menu data - all other parameters will be automatically loaded from the chip database.
When using 24xxx or 93xxx or 95xxx or 25xxx SPI EEPROM (non NOR FLASH) series chips, it is necessary to manually enter the Manufacture and Name pop-up menu data - all other parameters will be automatically loaded from the chip database.

Basic programmer operations

Pressing Read or or <Ctrl+R> to read data from the chip into the computer buffer.
Pressing or <Ctrl+W> to write data from the computer buffer into the chip.
Pressing or <Ctrl+E> will erase all data in the chip.
Pressing the or <Ctrl+T> button causes the data in the chip and in the computer buffer to be compared.

The progress bar shows the progress of the read, erase, and verify operations.

The Auto button is used to perform erase, write and verify operations in sequence. If one of these operations is not needed, you can uncheck the checkbox for that operation.
The or <Ctrl+I> key is used to force interruption of chip read/write/erase/verify operations.
The i key show the connection chip to CH341A device image form.
The Main menu -> Programmer -> Chip info or <Ctrl+P> item shows the Serial Flash Discoverable Parameter (SFDP) register and the status registers of the SPI NOR flash memory chips.

If the SPI NOR FLASH chip is detected normally, but is not read (gives the message Error reading sector 0), then in the Chip info window you can change bits BP4 and BP3 to zero and press the Write registers button. Then repeat the chip reading operation.

File operations

The or <Ctrl+S> button is used to save the computer buffer to a file.
The or <Ctrl+O> button is used to save the file in the computer buffer.
The or <Ctrl+Shift-S> button is used to save a part of the computer buffer to a file (the start address and length of the part must be entered). This operation can be used when splitting a binary data image into parts.
The or <Ctrl+Shift-S> button is used to load a small file to a certain address in the buffer. The data fragment in the buffer will be replaced with new data from the file.
The or <Ctrl+Q> button is used to invoke the chip database editor.
The menu item File / Import from Intel HEX is used to save the Intel HEX file in the computer buffer.
The menu item File / Export to Intel HEX is used to save the computer buffer to a file in Intel HEX format.

Buffer (Hex editor) operations

The hexadecimal chip editor (right side of the screen) is used to display and modify buffer data.

It contains the following controls: undo, redo, and the search/replace. The [Ctrl+A] key used to update the CRC24 checksum.

Chip database editor

Chip base editor - IMSProg_editor is a stand-alone program that can be launched from the Development menu or from the IMSProg program by clicking on .

All operations in the editor become available only after loading a chip base file with .Dat extension.

Menu File.

Open or [Ctrl+O] or allows you to load the data file.
Save or [Ctrl+S] or saves the chip parameter table to a database file.
Exit or [Ctrl+X] or - exits the editor.
Export to CSV format or [Ctrl+X] or allows to unload data about chips in CSV format for further processing by spreadsheet software - LibreOffice Calc, OpenOffice Calc, Google Tables, etc.
Import from CSV file or [Ctrl+Shift+X] or - loads a table in CSV format and adds data from it to the existing data in the table.

Menu Edit.

Delete Rows or Del or - deletes one or more rows.
Add Row or Ins or - adds a row below the selected row and copies all data from the selected row to the new row.
Move Up or '[Ctrl+Up]` or - moves the selected line up.
Move Down' or [Ctrl+Down]` or - moves the selected row down.
Import selected rows to CSV format or - saves selected rows to CSV file.

The most recent version of the chip database file can be downloaded from this page in both .Dat and .csv formats.

Chip updater

IMSProg_database_update uses the zenity graphical Gnome utility. Once started, it copies the downloaded database to the ~/.local/imsprog folder. The script then displays the number of of chips in the database before and after the upgrade.
