Hi
I want to make a programmer for 24Cxx family of EEPROMs. I am using JDM's following circuit:
**broken link removed**
I have 2 questions:
1. Can I use 9-pin serial instead of 25-pin? Will that disturb voltage levels as JDM has stated that it only works with RS-232 levels at < ±7V.
2. Can I only connect the required pins for EEPROM (boxed in green) and leave rest of the pins without having to worry about floating etc?
Thanks
Added after 10 minutes:
If not this circuit, can the uJDM work for EEPROM?
**broken link removed**
I believe it is for PIC only.
