Hey Mel,

If you or others are "reluctant to help when you haven't got a manual" ...because..."it usually applies to someone that has not acquired a legal copy (since the manual comes free with the...

LOL, all I wanted to do was avoid desoldering the original 10mhz SMT xtal with a 4mhz, but the desoldering took far less effort.
Thanks to all that replied anyhow.

John

one more thing....

"where do I find your book ?" = Melanie's manual
Melanie's manual = MicroEngineering Labs, Inc. PICBASIC PROtm Compilier manual
.....ok, thanks for that manwolf...

And...

Hi,

Yes I had cheched the manual, just didn't know or cared who wrote it. I don't run and post a question here or anywhere unless I just can't figure something out. I will read anything I can get...

MEL,

Your right, you did explain in post #4 that using DEFINE OSC was needed to adjust all required timings. You then said "There's also a whole section entitled "How fast is fast enough?"...

Hi Michael

The modules I am currently using with excellent results are called the Xbee Pro, I got mine from Digi at www.digi.com/products/wireless/zigbee-mesh/xbee-zb-module.jsp, their shipping is...

...........zzzzzzzzzzz

wow, thank you Sooo much for such useless information....

John

hmm...

skimask, what does " .....................ffffffffffffffffffftttt" mean ?

As for this manual/book at the bottom of my box, I'll let you know if I ever find that. It's probably still...

Thanks Melanie,

That explains my problems with any xtal other than 4mhz. I will check into my PBP manual for info about DEFINE OSC, but will that allow the use of other osc frequencies ?
Also,...

Hi DT,

Thanks for that reply. I am able to set all config fuses using the melabs U2 programmer software. I did set the 10mhz xtal to 'HSPLL' under xtal setting, which worked but is also the...

Depending on your application, you might consider trying the Digi Xbee modules. They are super small with excellent range and built in encryption and error checking. They operate in the 2.4ghz band...

Hello,

I recently bought a pic/xbee robotic controller board online from www.droids.it . I must say the price was alright and the pcb quality is excellent BUT I just cant figure this one out. It...

Thanks again Paul, that appears to be exactly what I need to get started on this. I'll give it a try when I get home tomorrow and let ya know.

John.

hahaha,

That actually cracked me up Paul. Thanks alot guys for the replies. Yesterday I was at a point in my project that you have all been I'm sure-STUCK. So you say to drive the enable pins with...

Hi again(to myself),

I must have mistaken this forum for a place where answers are pleantifull OR this is mostly a programming based group. BUT for anyone who is interested in what I was trying to...

hmmmm......

Does anybody have any experience with this type of motor control ? Any info would be appreciated....

John.

Hello,

I'm trying to drive two small 6v motors and want to be able to control both speed and direction independently. Currently I am running a dual H-bridge (L293) with the '873, but that only...

Hello,

I have a simple serial relay controller setup using two pics, one for the transmitter and one for the receiver. Using the "serout2" command I can send control data to the RX. The RX code...

hmm.. .

Doing some more testing with a2d I've noticed that in order to get an accurate voltage reading for example on porta.0, the input must come from some form of voltage divider with both 0 and...

Hey,

Thanks alot Brian, that write up is quite good but I'm still not sure how to implement the formula into pbp based on my current program setup. For example, the formula has a 'v' volts...

Hi,

Thanks to replies to my last post, I now have 4 channels of ADC to serial LCD working great on a pic16f877/04. With my current setup, I can measure 0-5 volts on ch 0. Channel 1 is for...

hi,

Thanks alot for your prompt reply mister e ! I will try that code change and see what happens. A few more questions: is any type of pullup/down resistor required on the adc input, or would...

Hi,

I am fairly new to this whole pic chip thing, and loving it !
I'm building a small (hopefully autonomous) robot and slowly I'm getting close to my goal.
Using a set of Ewave radios and the...
