Hello everyone,
im new to these forums and using micro-controllers so excuse me if i make any silly mistakes.
I have recently brought a few things directly from the basic micro website here is my receipt
Code:
   B0094 Switch SPDT $0.70 x 4  $2.80
   B0075 1N4148 Diode $0.15 x 4  $0.60
   B0074 Resistor 1MEG Ohm 1/4 Watt $0.15 x 4  $0.60
   B0068 DIP Socket Solder - 28 Pin 0.3" $0.49 x 2  $0.98
   B0062 Ceramic Resonator 20MHz $0.89 x 4  $3.56
   B0012 Nano 28X $10.95 x 1  $10.95

I received all of the components but the micro-controller is a Nano 28 instead of a Nano 28X as ordered. I emailed basic micro 28/03/2011 2:59 PM Australian EST, and due to my impatience i have resorted to posting here. Is this all I need to do to resolve this situation?
I am from Australia.
Thanks heaps

I believe you already got replied to by email but if not, yes that is all you need to do(emailing us). Sorry for the inconvenience.

there is one thing I'd like to check. Have you tried using the chip yet? I don't beleive we have sickers for NanoX chips yet so it is possible that is a NanoX even if the sticker doesn't explicitly say it. You can safely hook a Nano chip up to a resonator without damage. It just won't use the resonator. Then use the Find option in BasicMicro Studio to see what it says it is.

Alright thanks,
I haven't received an email yet i have checked my junk and it isnt in there either.
I have wired it up with a resinator and without, both the the schematics for the RS232 data transfer 28x and the 28.. amazingly i havent got any of them to work but i will try again today in school.
thanks for your help

Sorry for the double post, but the nano 28x can be plugged directly into a computers serial port right? using the schematic in the datasheet.
thanks

NO, You'll need a level (RS-232) converter

explains why it doesnt work then :P, thanks alot for your help.. i am yet to see if it is a 28 or a 28x because i lack the converter

Also if you did plug it directly into a PC rs-232 port you may have damaged it. Others have done so and got lucky but most PC rs-232 ports put out -12 volts. Negative voltage is even worse than overvoltage so cross your fingures.

mm yeah, i set it up exactly the way the schematic bread board view did and didn't notice that the ground wire was connected to the VCC section and it got really hot, i think i destroyed it so lets see.. i just brought one of these :http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=180528593122&ssPageName=STRK:MEWNX:IT because i lack the money to get the one off the basic micro website (the postage to Aus) that module should work shouldn't it?

That could work. You'll need different drivers, 'tho for the CP2102.

And you'll probably have to configure a handshake line to allow programming.

Is it that much (shipping/customs) for the little programmer ?

The cp2102 should work. We used them a long time ago, they were just difficult to assemble because there were qfn(leadless) back then so we switched to FTDI.

If the Nano chip got really hot, it may still function. Nanos are PICmicros which can take a lot of beating before they fail.

I've powered up PICs incorrectly before, and they've still worked. I didn't ship them 'tho!

The RS-232 levels from a laptop might not be up to a full +-12, so you might luck out as Nathan has noted.

And didn't I remember a drawing for a S_OUT interface with just simple transistors and diodes? In a manual for the Nano, No?

Thanks heaps everyone for your help and advice it is very much apreciated, lets hope it works. I have the drivers for the usb programmer so it should be all good.
thanks again

For some reason i cant edit my post, so i apologise again for double posting, i think i have proven that it wasn't an incorrect order :P, i wired it up correctly today at school (without the programmer lines plugged in obviously), and i measured the frequency with the oscilloscope over the resonator and it got 20MHz so i guess it is a 28x, also it was putting out 100mV, does that mean my chip isn't dead??
thanks again again :P

Atleast part of it is working. The 20mhz res wouldn't run if the chip wasn't setup to drive it. You have to run some tests to make sure everything else is working, particularly the s_in/s_out pin. Thats the most likely part damaged if you hooked rs-232 signals directly to it.
