 Bigger Bigger  Smaller Smaller  Reset Reset

Hello guys

i have a question.

I want to programm a ATmega644p with my Arduino UNO. I found a picture in the Internet.


But i can't buy somewhere.

Now the question:

Can i put with an adapter an ATmega644p on the Socket?

I draw a sketch with a schema, but i didn't know if this possible.


Thanks

with kind regards Ratlos

Arduino Uno can be used as an ordinary ISP programmer for writing many AVRs including an Atmega644p:

the only connections you need are
+5
GND
Reset
MISO
MOSI
SCLCK

and you can just jumper them over with a breadboard ... whats going to be harder is finding a 1.0 compatible core and bootloader for the 644p that works out of the box

thanks for the info.

I want to use the sanguino firmware.

I hope to use the Arduino as USB-TTL converter to upload a sketch.

If this possible?

This instruction is very expensive smiley-sad

Why not put your own board together?

I sell this bare board for $5 with USPS shipping.
PL is here
http://www.crossroadsfencing.com/BobuinoRev17/
Accepts any of the ATMega164/324/644/1284 family of devices.
Use an onboard FTDI module, mikroe483 from mouser.com, or an offbaord FTDI module/cable or equivalent CP2102 module.
Use maniacbug's 1284 core files setup & program it like any other board.
