4074.0. "Mouse Joy from C hw example" by BIGIST::SYSTEM () Mon Sep 03 1990 07:52

    
    I want to read port Joystick and Mouse ports from C. I have two
    dismantled josticks plugged into the back which gives me an array
    of 10 microswitches to experiment with.
    
    Having read a few good amiga programming books, I have some example
    C for reading the ports. Cant I simply read some port addresses to 
    get this device data (I know its meant to be all polite mtasking code
    through a device etc. But Im the only one on my Amy and I like to get
    some things a little quick if by being a little naughty)
                                                            
    I did see some example code somewhere to do this in C, with thingies
    included like <hardware/custom.h> and CIAxxx defines, but now that
    I want it! You know how it is.
    
    
    Anyone seen such an example??
    
    Marc.

	I think you need to use the POTGO resources to get at them in a multi-tasking way. Look in the WJG::AMIGA:EXAMPLES.ZOO, GURUS.ZOO files. There are lots of examples there. One may have joy stick port stuff... john
4074.2	I remember the source...	BIGIST::SYSTEM		`Mon Sep 03 1990 12:32`	15
	Thanks for the pointer, but they dont seem to contain exactly what Im looking for. However, I do remember where I saw the example. It was in an Amiga magazine available here in UK. Amiga Format it might have been,but the series it runs is called "The Code Clinic" Does somebody out there, get this mag with the code clinic?? It normally has a PD disk stuck on the front (hopefully with the actual source I am after) I knew I should have bought it at the time! If anyone has this disk Ill swap them a knackered old game for it ;-) Marc.
4074.3	September Amiga Computing.	TAGART::ATHOMSON	C'mon, git aff! /The Kelty Clippie	`Tue Sep 04 1990 08:26`	5
	The mag that runs the code clinic is Amiga Computing, and the September issue disk has a joy.c in it. Mail me if you want it. Alan T.
4074.4	FF344	WELLIN::FINNIS		`Tue Sep 04 1990 18:40`	9
	Check out Fred Fish #344 on TAPE:: This contains the RKM_Companion Source files.. I believe this is what you require.. - Pete - ( The Node Hopper )
4074.5	Great but documentation??	BIGIST::SYSTEM		`Wed Sep 05 1990 11:06`	15
	Thanks, the FF disk in.-1 has exactly what Im after and much much besides! However having compiled and run the example I have a number of questions. Where is this potgo.resource documented?? Can anyone who has used it post a listing of what bits get masked for what, in the call to AllocPotBits? ie. Its a ULONG mask defining which bits you want to allocate, but which bits relate to which pins,buttons etc. Marc.
