Eetu Pesonen / AVR EEPROM Programmer - History

On the way to a working device

I built a (more or less) prototype version of the programmer on protoboard
today, and the code is now for testing (sketch.ino). Everything seems to work,
but a (maybe just Arduino-related) problem has occured: according to my
measurements, the logic LOW of the Arduino floats around 0.8..2.8 volts,
which means that the LOW level wont (always) be registered as LOW by the mem
chip, but rather as a HIGH -> pulldown resistors, maybe?

Also, the shiftreg writing system got simplified (I grew a brain and figured
out bitshifting..) -> better.

schematic

The schematic of the programmer can be found from the schematic directory.
Removed the shift register of the data channel, so now data is written
directly to the memory chip's pins. This change makes verification of
the data written to the chip very easy.

To view the schematic, you'll need the arduino_pro_mini.lbr file (in the
schematic directory).
