BASIC for the PIC (programming)

I am looking to do some programming on some PIC MCUs in the near future. I have two boards sitting around my office. One take a 9 pin serial and the other takes a USB. I am really not a Assembly or C developer and I am resistant to go down that path unless I am really in love with the platform.



A friend at work owns and recommends the Mikro line. I am in interested in Mikro and
Proton and think that Great Cow might be interesting just to see what it looks like.

Here are some other links and notes that I dug up a couple of weeks ago:



Looks nice.. but it appears that new development is slowing down on this package

Some people use this for a 18 series PIC.

Transistor Impedance (more)

Here are some low frequency examples:






Rc is the resistor at the collector   -   Re is
the resistor at the emitter




This model assumes that you are getting your RF from a tap between the collector and
collector resistor.



http://en.wikipedia.org/wiki/Common_emitter




I am still working on trying to figure out this impedance thing. N0FP added another
bit of complexity... what happens if you have a tank circuit vs. no tank circuit. 
... Argghhh.



I need to pull out SSDRA and do some more reading or re-reading as the case might
be.

Transistor Impedance

I am trying to figure out how to calculate the input and output impedance for transistors. (Kind of an important detail when you are designing radio gear.)



The link below has some interesting examples. I grabbed some screen captures of them
in case they eventually fade away on the internet like so many good things do.





http://hyperphysics.phy-astr.gsu.edu/Hbase/Electronic/tranimped.html



















The challenge that I have with these examples are that they appear to be DC values.
I live in an RF world which means we are talking about AC or even more complex is
DC & AC at the same time.

Here is another link that I like:

http://www.geofex.com/article_folders/impednc.htm




I have seen/read other examples like this where you roll up the values and get to
an approximate value.




This still bothers me.  Why is it so hard to figure it out?  We should be
able to calculate it and measure it. This feels kind of elusive and black boxish. 
....arghhh.

--------------------



I have a Laser printer and several Inket printers. It appears that my Epson RX595
has the right kind of ink and a CD print tray. It looks like this might be magic to
be able to do direct printing on a copper PCB.
