# Normally takes 196 seconds to program a 28C64, and 32 seconds to read. Its a simple EEPROM programmer shield, designed to sit on top of an Arduino Mega 2560. I was getting tired of dragging out the UV Lamp. New keyestudio MEGA 2560 R3 development board USB cable compatible for arduino. Heres the story about the Arduino UNO based Flash EEPROM Programmer for the ATMEL AT28C256 32K EEPROM. The Arduino and Genuino 101 boards have an emulated EEPROM space of 1024 bytes.

Python programming script (still a lot of issues - Linux: Need minicom to connect first and leave without reset OSX: doesn't work at all - always get 'eh'): #!/usr/bin/env python2.7 TL866II Plus USB High Performance EEPROM Flash BIOS Programmer for ATMEL. The supported micro-controllers on the various Arduino and Genuino boards have different amounts of EEPROM: 1024 bytes on the ATmega328P, 512 bytes on the ATmega168 and ATmega8, 4 KB (4096 bytes) on the ATmega1280 and ATmega2560. - Introduced + and - to alter k_uTime_WritePulse_uS - corrected SDP (un)protect adresses & k_uTime_WriteDelay_uS delayMicroseconds(k_uTime_WritePulse_uS) static const long int k_uTime_WriteDelay_uS = 500 // delay between byte writes - needed for at28c16

Reading and writing is now orders-of-magnitude quicker. during reads and writes were about 10,000 times too big! - properly looked at timings on the Atmel datasheet, and worked out that my delays In this video I make a EEprom programmer for the ST95020 EEprom that will work in circuit for the 2003 to 2007 GM instrument clusters.
