I made some words for manipulating pins on pic18.
Any comments or suggestions for the names and structure ?
Is there any best practice for pin manipulation ?
Would it be better to have pin-in: and pin-out: instead of pin-dir: ?
BR Mike

It is good idea to use such words, but I think their usage belongs not to the pins only. Any bit usable in similar way. According to this theory the terminology probably: bit-on: bit-off: bit-test: (or bit?:) The name of defined word can refer to its function, such as usage of a pin or function of a bit of a sfr etc. BR Attila ----- Eredeti üzenet ----- Feladó: Mikael Nordman <mik...@pp...> Dátum: Kedd, Március 25, 2014 8:08 Tárgy: [Flashforth-devel] Pin words Címzett: fla...@li... > I made some words for manipulating pins on pic18. > > Any comments or suggestions for the names and structure ? > > Is there any best practice for pin manipulation ? > > Would it be better to have pin-in: and pin-out: instead of pin-dir: ? > > BR Mike > > \ ********************************************************************* > \ * > \ Filename: pins.txt * > \ Date: 25.03.2014 * > \ FF Version: 5.0 * > \ MCU: PIC18 * > \ Copyright: Mikael Nordman > * > \ Author: Mikael Nordman > * > \ ********************************************************************* > \ FlashForth is licensed acording to the GNU General Public License* > \ ********************************************************************* > \ Words for manipulating I/O pins > -pins > marker -pins > > \ Define a word that sets a pin direction > ( tris bit dir "name" -- ) \ dir : 0 = output, 1 = input > : pin-dir: > : > if > a, bsf, > else > a, bcf, > then > $12 i, postpone [ > ; > > \ Define a word that sets an output pin > ( port bit "name" -- ) > : pin-on: > : a, bsf, $12 i, postpone [ > ; > > \ Define a word that clears an output pin > ( port bit "name" -- ) > : pin-off: > : a, bcf, $12 i, postpone [ > ; > > \ Define a word that leaves a true flag if a bit is one > \ and a false flag if a bit is zero. > ( port bit "name" -- ) > : pin-in: > : > ['] false in, > a, btfss, > $12 i, > ['] invert in, > $12 i, postpone [ > ; > > $ff82 constant portc > $ff94 constant trisc > $0000 constant bit0 > > trisc bit0 0 pin-dir: pc0out > trisc bit0 1 pin-dir: pc0in > portc bit0 pin-on: pc0on > portc bit0 pin-off: pc0off > portc bit0 pin-in: pc0? > > > ------------------------------------------------------------------------------ > Learn Graph Databases - Download FREE O'Reilly Book > "Graph Databases" is the definitive new guide to graph databases and their > applications.

Well said Herman, I agree...

Since these words actually only work with SFRs in access ram they could be called sfrbit-on: sfrbit-off: sfrbit-test: The words that work with the whole ram space could be bit-on: bit-off: bit-test: These words need to generate code to set the bank bits also.

Really, this distinction needed for optimal speed.

Sorry for my poor english... I want to say, I agree with using different words for SFRs and whole ram.
