Let's Make Robots!

Total beginner with a PIC question

Right so Im a trainee at the university as a technician..

 

Work's have provided me with a University made microcontroller board with a PIC18F4520 on it...

 

Im a total newb with electronics and Im finding it hard getting to grips with this board, I really want to follow the tutorial with the 85$ robot and for that it requires a PICAXE board...

 

What I want to know is, for a first timer would it be hard to do it using the 18f4520, bearing in mind I have nearly zero programming experience or would it be easier to just follow the pre written code and just buy the PICAXE, money isnt so much of an issue up to a point..

 

Any advice by the way for a first timer would be great

 

I love the videos and the site and hope to become a part of your community! 

 Regards

Hello Everybody!

I'm a beginner with PIC and I started of with making the PIC serial programmer. But it isnt working and i've been banging my head on it. A voltage of 10 V is reaching till the IN4148 P-end and it drops to 0 and the N-end. Thus i'm not getting any voltage between pin 5 and 14 of my PIC16F84A.

Please Help.

 

Thanks 

 

If voltage isn't crossing the 4148 then you've either got it inserted backwards, or it's broken. Swap the diode around or replace it altogether.
Tried both already. No use.

The 78L05 could also potentially be the culprit, although it's less likely. Why don't you start a new post, preferably with some photos of your circuit, it'll be easier to get help that way.

Ok Thanks. I'll do that.

hello.. im a student from malaysia,,

here in malaysia, the technology we have are very low.. i am only familiar with c programing.. know a lil bit of asembly..

i only know how to use the pic16f877a  and the bourd available for me is sk40b, but i can build my own bourd but it would be bigger in size,

 

this is the bourd available for me, and ive used it before for some of my simple project.

the PIC18F4520 just enter our country recently.

i dont know much about your new PIC.

 

is it posible for me to build a simple robot wif what i have.?

where can i get examples of c programing source code for a simple robot for me to learn and start modifiying it for my personal hoby project?

 

Look for any project on here that uses an arduino the cost should be in C.

C is definitely the way to go....I know MPLab (for PICs) lets you interject with assembly if you want, but that might actually be part of the C language.

Thanks for the advice..

 

 

I think that makes sense, Im gonna order the PICAXE next week and while i waiting for delivery have a go at flashing some LED's etc with my board.

 

I'm gonna have to learn all this eventually as I work in a microcomputer department lol, but I'm still really new at electronics, which is the reason I was searching for PIC tutorials for a project I could get my teeth into. Most of the academics in our place dont have much time for beginners help....so anyway happened to stumble upon this site. Glad I did!

 

Anyway cheers.. Ill keep you all posted with my first robot and Im guessing probably more questions as It goes along.

 

 

I agree that if you are new to electronics and programming then the picaxe is a better starting point. The basic language is fairly easy to learn, the manuals are all free downloads and you will get plenty of help on this site. Once you have a basic understanding of robots then you will be ready to use the board you have been given.
