How to Install IMSProg (I2C EEPROM programmer for CH341A) in Ubuntu

Got a CH341a series USB programmer? Here’s a graphical free I2C EEPROM programmer tool for Linux Desktop.

There are a number of programs for Windows, such as CH341Programmer, NEOProgrammer, and ASProgrammer, for working with popular “green” and “black” CH341a devices, but it lacks a graphical interface for Linux.

So, Linux IMSProg was born to provides a graphical interface to read, write, erase and test I2C, SPI and MicroWire EEPROM/Flash chips (24xxx, 25xxx, 93xxx, 95xxx series).

It’s a free open-source tool based on Qt5, that uses QHexEdit2 for hex editor widget and a modified set of the SNANDer programmer libraries.
