HI:

I wish program with nt this eeprom 24LC02
Datasheet:


USBJTAG EEPROM
Pin 2 ----> pin 4
pin 5 ----> pin 5 (?) not sure
pin 9 ----> pin 6 (?) not sure...

Usbttl 3.3v -----> pin 8 eeprom
But how can connect to NT device eeprom pins X and Y ?

It is assumed that does not support this eeprom because it appears in the program settings, but do not know how the pins are connected ...

thanks

Ok, this is the diagram that shows nt


But someone can help me understand? what kind of resistance is requered?

Have not played for a while. Try 4.7K first. If it works then it is OK. If not then try 10K or 1K.

Ok bdm. GND is it???

EEPROM ---------------------> USBJTAGNT
PINS (1,2,3,4,5,7,8) ------> PIN 6



Please confirm...thanks

USB JTAG NT GND is 2,4,6,8,10.
You can check this pinout in the user manual pdf.

I know, but the diagram is not clear...

for example: connection for all usb jtag GND pins (2,4,6,8,10) like this:

EEPROM --------- USBJTAG NT
PINS 1,2,3,4,7 ------> 2,4,6,8,10

or like this:

EEPROM --------- USBJTAG NT
PINS 1,2,3,4,7 ------> 6
