Ahh...Yes, Yet another AVR nubie....

2004-10-18 by John Allen

Hi Gang...!!

I was searching for a new MCU and started looking at the AVR line of 
MCU chips. I had seen the butterfly card for $20 and having read the 
chat from here decided to get the "carrier" board kit from echos for 
$20 to go with that. I also got the Bascom program for $85 from 
Rhombus. Now for the nubie question.... Will the serial port from 
the carrier board be reconised by the Bascom program, or will I need 
an ISP or JTAG device also..?

I am tring to put together a simple cheep platform the eval the "new 
toolchain" before I consider using it to produce the new project I 
need. 

I am looking to construct an electronic lock that works as a "stand 
alone" device. It needs a RTC, a large SPI based EEprom or Flash 
based addon. (2megx8) for database record and transaction log 
storage. I want to be able to use an ATmega128 as the baseband MCU 
and write the code usuing the Bascom compiler. BUT ... The kicker is 
how to get the DATA exchanged between the user of the device ad a PC 
or laptop...???   DING...  Use a CF memory card, (hey, there cheep) 
and use the AVR DOS fileing system to write the transaction logs to 
the CFcard.  Then I could write the whole thing using Basic..!!!

Yea..!!  What a deal...   but has anyone auctually doe this yet...


Thanks for reading all the babble..!!!

I can't really answer this, but I looked around on the Web and it 
seems that you might need a programmer. ISP interfaces are cheaper 
than JTAG interfaces. You might be able to throw one together with 
parts from your spares drawer. Most ISP interfaces have a 10-pin 
header, so you might benefit from my 10-pin to 6-pin adapter. If you 
would like me to hold your order for the Butterfly Carrier while you 
sort this out, just let me know. Otherwise, it will go out by 
Priority Mail tomorrow.

If Bascom can load a program without an ISP (or JTAG) interface, it 
will be with the help of a flash loader program (also known as a boot 
loader) in the target MCU. The Butterfly does have such a loader as 
shipped by Atmel. So, it depends on whether Bascom can talk to that 
loader or output an Intel HEX file which you can load with AVR Prog.

I hope someone else can be more helpful. There are many Bascom users 
here and someone is sure to know. I wonder if Bascom can drive a JTAG 
ICE interface?

They are very different. The Jtag also programs chips, but they are not 
interchangeable.
If you can afford it, a Jtag will be a big help.  AVR-Studio is what you 
need to drive the ice.

I remember a person posting photos of his AVR based lock over on www.avrfreaks.com

Maybe search the forums there or pose a question there too?

I'm sure you'll find people who've built locks

Actually with the butterfly, programming is real simple, it has a
serial port on it, you just need to wire it up, you can get the info
from the datasheet.
