Noob question!! Spin Manual?

Farthinder

I Hope you can excuse a noob question but is there a Spin Manual?

I have found plenty manuals on the Propeller with Spin programing examples but is there a Manual/website dedicated to the Spin language?

The manual of the demo board (downloadable) has a large section containing a SPIN reference. Helped me a lot.

Hello Farthinder and welcome to the Propeller-forum,

what kind of information do you miss in the things you found ?

There is the http://propeller.wikispaces.com/ but I think it is not exactly what you wish

best regards

Thanks Stefan!

I was looking for a general guide to the Spin language but as VirtuPIC said there is already alot of info on it in the manuals.

How ever i have got and other question for you, i recently got the Pro Dev Board of one of Parallaxes suppliers and i have been playing around with it a little bit. Among many other things its got LED Segmented displays, they work by you first applying ground to one of the 6 digits you wanna light and then + to the segment in that digit you want to light. So my question is how can you make the propeller switch from digit to digit seeing as you have to apply ground to different legs not +.

The Propeller I/O pins have 3 states (as do those of most microprocessors), input, output high, and output low. In output high, the I/O pin gets connected to +Vdd (3.3V). In output low, the I/O pins gets connected to Vss (ground). The corresponding bit of DIRA has to be set to a one to set output mode and the corresponding bit of OUTA gives the state (high - 1, low - 0).

You connect each digit to one I/O pin and each segment of all digits to one I/O pin.
