Add USB to any PIC project for less then $3

Noticed this crystal is a suggested crystal in the MCP2200 datasheet. .42 in singles at Mouser and has built in capacitance, so no external caps needed.

CSTCE12M0G55-R0 Murata Resonators

Why wont it work in Parallel? a 18pf and 10pf heh

**broken link removed**

Im no pro but thats what i would do ...

 

[AtomSoft]

Nice work Mark!!! i just added it to my basket heh. I love SMT then you had to go and make it be a Resonator type ... man its a all in one solution...

Thanks again. I probably would have been using a Cap and Crystal forever heh

Also it says the capacitance can be 30/33/39pF

so 39pf can be used?

In the datasheet for MCP2200 they have a example of:

Also

Page 19 ; x1 = CSTCE12M0G15L99-R0

So heh there the same brand too

Hmm, resonators are not noted for their accuracy...here's a .1% version...same price

**broken link removed**

Im no pro but thats what i would do ...

I feel that two numbers of 22pF, one on each side, are enough. and no need to be too specific .

I figure you all may want this program someday It's a great terminal program that really lets you take control of the Pc com port http://www.hackinglab.org/icybie/Terminal.exe

 

[Mosaic]

looks good!!

 

[AtomSoft]

yeah,. i hesitated at first since its a exe and from a site called "hackinglab" heh makes you think a bit.... but then i thought heh its Burt... hes legit!

 

[be80be]

It's a good program You can even program chips with it. The old school way

 

[AtomSoft]

Looks full featured heh like i can do anything needed with it heh... ill test it right now

Ah... cant select custom PORT my MCP2200 is on COM8... ill have to change it heh

 

[AtomSoft]

Nice here is a small token of data from my Accelerometer UART... i have it set at 4800bps... (for now)

58 00 00 02 00 00 00 58 00 00 02 00 00 00 58 00

58 = 0x58 which is the signal to collect the next 6 bytes of data which is, Xn,XH,XL,Yn,YH,YL

Xn is a flag to signify X is NEGATIVE
XH is the upper byte of int X
XL is the lower byte of int X

Y is the same as X but well... Y

So " 58 00 00 02 01 00 01" would be Start, X=+2,Y=-1
Simple heh

This all falls into this USB post since its from the MCP2200... I miss my FTDI but too expensive... I like it more because i dont have to worry about crystal/resonator heh. But price matters a ton these days.

You can alias com ports but that a book in it self Google aliasing serial com ports for windows xp you'll see what I mean

And when you get into Linux you get real power over Com ports

 

[AtomSoft]

Yeah i get it heh... Yet another reason to play with Linux... heh

 

[AtomSoft]

On the topic of linux and usb and PIC you think it would be harder or easier to write straight USB code for LINUX?

 

[be80be]

Linux has a lot out there as way of code that you could learn by and reuse. I think as good as you are at C you'll be more at home with Linux

 

[AtomSoft]

heh thanks for the complement. Im learning as i go.

Slight off topic right here... i play lotto now almost everyday... hoping to win big... if i do i plan on buying a little set of things and hosting a contest here on the forums. Maybe like $500 worth of stuff... like sensors, buttons and a whole starter kit to making PCBs (including a printer)....

So do me a favor and wish me luck guys... if i get it ill host something ... and some people will win.. (of course there will be 2nd and 3rd prizes)

ok back on topic... I am going to setup a PC i have on the side with Linux and see how it goes. I hear Ubuntu is like all the rage in the linux world heh

All the best of success in your learning Atomsoft !!
