Do I have an 18X or an 18M?

[chigley]

Just found an 18 leg PICAXE in my box, how would I go about identifying it specifically?

On the front it says "PIC16F819".

Cheers

Isn't there a feature in the programming editor to report this?

I'm not at my "lab" at the moment so can't check double check, I'm certain I've seen it!

regards,

direct from PICAXE Manual 1 page 12:

PICAXE chip labels
PICAXE chips are pre-programmed and tested Microchip PICmicro™
microcontrollers. They are therefore ‘stamped’ with the Microchip part name.
• PICAXE-08 PIC12F629
• PICAXE-08M PIC12F683
• PICAXE-14M PIC16F684
• PICAXE-18M PIC16F819
• PICAXE-18X PIC16F88
• PICAXE-20M PIC16F677
• PICAXE-20X2 PIC18F14K22
• PICAXE-28X1 PIC16F886
• PICAXE-28X2 PIC18F2520 (3V version PIC18F25K20)
• PICAXE-40X1 PIC16F887
• PICAXE-40X2 PIC18F4520 (3V Version PIC18F45K20)
• PICAXE-18 PIC16F627(A) Superseded by 18M
• PICAXE-18A PIC16F819 Superseded by 18M
• PICAXE-28A PIC16F872 Superseded by 28X1
• PICAXE-28X PIC16F873A Superseded by 28X1
• PICAXE-40X PIC16F874A Superseded by 40X1

the data is in the manuals - just need to look

@westaust55 - Hmm I did look, obviously not for the right things! Thanks a lot

@slurp - There is a feature, yes, found that too.

The 'firmware' function is very useful. The only way to tell the difference between an 18A and an 18M.

@chigley.
Serious advice.

Once you have identified your chips, label them.

The nicest and neatest way is
http://194.201.138.187/epages/Store.storefront/?ObjectPath=/Shops/Store.TechSupplies/Products/LabelMaster/SubProducts/LAB001

Otherwise, the Untidy way is a pound-shop correction pen.

Once you have built a collection of assorted chips,
it can be very easy to put the wrong chip in a socket,
and break things. :-((

PICAXE Labels

Here is a link to some of my earlier attempts on PICAXE and related IC labelling.

can take a few seconds to divert to the exact post . . give it time

I've just spent 10 minutes labelling all of my chips - went for a budget method involving envelope labels, a biro, and some scissors!

I've left the 18M (I think!) one blank for now, as I want to use the firmware function to check that I'm right, as Andrew's post above mentions an 18A.

Just use a silver marker pen - works a treat and seems durable.
