Hi. Soldered Your programmer. A very attractive scheme and implementation. Successfully programmed microcontrollers PIC. But, when I tried to write to the EEPROM memory 93lc46 get an error message. Maybe I'm not doing all right? Supported eeprom 93lc46 in 8 pin socket, on the basic Board? I did so:
1. Unplug the USB.
2. Put eeprom 93lc46 in 8 pin socket on the basic Board.
3. Insert the USB.
4. Choose the type of chip eeprom.
5. Do re-connecting.
6. Click on the icon of the "read from the chip" . Get the message that the chip is empty, and dump filled with zeros. Although I am sure that in the eeprom data are available.
7. Uploading a file with an extension bin, a copy of the data with the same chip.
8. Click on the button "Write in a chip" , програматор honestly writes, showing the address and data, but when checking reads the eeprom only zeros.
What am I doing wrong? Please help out. Expansion cards I have not yet done.

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Sorry, can delete topic, figured out what was wrong. Normal read and write eeprom 93lc46. The author of this programmer, thank you very much for development. Do not drop it, it is a very promising device. All the while, and good luck.
