README.md

Programmer for EPROM 27 series (16-512) based on Arduino

You can download the stable version on the "Releases" tab. It guarantees a working version of the source code, compiled by the GUI for Windows and a sketch for arduino.

Compatible Chips List (not all chips are tested):

27C16 (connects from 3 to 26 leg DIP28 socket)
27C32 (connects from 3 to 26 leg DIP28 socket)
27C64
27C128
27C256
27C512

Before write, check programming voltage in datasheet!

Schematic

Based on the project: https://github.com/bouletmarc/BMBurner

PCB divorced using autotracer. Not yet tested, but the prototype is working properly.

Resistors R1 and R2 are indicated in the Arduino firmware. By default, the values are 10 kOhm and 1.5 kOhm.

Software

Software for PC written by Qt5.

Functions:

Read chip
Write chip
Verify and check for write (no bits to be set to 1)
Programming voltage control (for AVR in TQFP case)

Requared Windows 7 or later.
