I have a question. I am making a game with another board by BBC, and using Arduino as storage. I want to know how can I Do this. It is transferring info via TX and RX.
THX
It is transferring info via TX and RX.
What is? Transferring data to what?
Serial data consists of bytes. EEPROM stores bytes. What a perfect fit. What IS the problem?
The arduino and BBC micro:bit
transferring via RX and TX?
really?
According to it's website, it has Bluetooth BLE and a "radio"
The radio is for communication to another BBC micro:bit.
It does have a USB for downloading programs into the BBC micro:bit and for powering it.
I am not seeing where RX / TX is possible.
You may not see it, but you can set it up.serial.redirect(SerialPin.P0, SerialPin.P1, 9600)
Giga_question:
You may not see it, but you can set it up.serial.redirect(SerialPin.P0, SerialPin.P1, 9600)
And where is this information?
Anyway, serial into Arduino then Arduino write to EEPROM
or Arduino read from EEPROM then serial from Arduino to BBC micro:bit
You need to write the code on both ends.
Ok thanks for being patient with me.
You've answered quite well THX
HI , I'm new in using eeprom storage i want to store last command in may arduino during power interaction , GMS to arduino Im sending character 'a' in GSM , how can i save in the eeprom of arduino, any one can help me. Thanks
my code is working in arduino using GSM and Bluetooth my problem is during power interaction , i need to store the last command.
I don't know much about coding in with bluetooth, but if there is such thing as a incoming bluetooth string then I would set a variable in voidloop() to bluetooth strings then put
EEPROM.write(address, bluetoothstring)
Or something like that
i need to store the last command.
Permission granted. If you need help, POST YOUR CODE.
I send character both Bluetooth and GSM , but i don't know to save in eeprom in arduino
may be i will post my code , I hope you can help me . thanks

Hi, i posted my code both Bluetooth and GSM please help on how to save the character in in eeprom in arduino, i hope you can help me in my problem .. Thanks

Have you even looked at the documentation for the EEPROM library? It could hardly be simpler to use.
Get rid of the useless label and stupid goto statement.
Yes, I looked the library , I can't save the character 'a' from GSM to arduino .. Can you please help me on how to do it.. Example on how to save 'a' GSM to arduino EEPROM..Thanks
i use:
EEPROM.read( address )
EEPROM.write( address, value )
Example on how to save 'a' GSM to arduino EEPROM.
Why 'is' a in "quotes" '?'
Can # you @ see % how ^ extraneous & symbols * create ( more ) confusion + than - they & solve?
A GSM is a piece of hardware. You can't store hardware in EEPROM.
In terms of the code in some reply, just WHAT do you want to store in EEPROM?
I want to save my last command in EEPROM like example I send 'a' to GSM and the power interaction encounter .
