![]() The programmer uses standard x-modem, as provided by any respectable terminal program-and certainly all of theĪbove listed terminal programs-to put binary files onto the eeprom. It doesn't affect the chip in any way, but tells the programmer what size your chip is for the erase, fill and read commands and error checking in the xmodem transfer. I use the following:īe sure to set the size of your target eeprom with the s command before doing anything. x - xmodem transfer binary file to eepromĪny standard terminal program can be used to talk to the programmer.f - fill eeprom with incrementing bytes.The Arduino Nano sketch implements a serial interface to the programmer. The design is based on this one, from Ben Eater. ![]() B), so any of those eeproms should work up to the 32kx8 chips. A) but has been updated to connect all address lines for the 28cx series (rev. The schematic started out only targeting 8kx8 chips (rev. An Arduino Nano sketch and schematic for an Atmel 28cx programmer. ![]()
