Post by thread:Simplfying Code ?

Greetings: Can a register and a particular bit be assigned a name. ie... btfss snyc Where snyc would represent 6,1 I tried equate with no luck, maybe a macro ? Joseph D. West Electronics Lab. Supervisor College of Mechanical Eng. Ohio State University (614) 292-2845 Fax (614) 292-3163

For example, in a prototype I may have IIC memory. SDA connected to porta, 0 and SCL to porta, 1. In my code I would have #define SDA porta, 0 #define SCL porta, 1 and later would have a routine which read data from the IIC device and would refer to the port pins using only SDA and SCL: bcf SDA ; example only - not proper code :-) bsf SCL bcf SCL btfss SDA ... return When I come to layout the PCB, I might find that the layout is significantly easier if the pins were swapped. All I need to do is change the #define lines. Also, if you want to change the direction of the port pin you can use the same #defined text. eg: bsf status, rp0 ; goto page 1 bsf trisa, 0 ; produces the same code as bsf SDA bcf status, rp0 ; back to page 1 I hope this helps, Mike Watson

Try this: #define snyc 6,1 Regards, Octavio ======================================================== Octavio Nogueira e-mail: nogueiraKILLspammandic.com.br homepage: www.geocities.com/SiliconValley/Pines/6902/index.html voice/fax: +55 11 240-6474 "ProPic" The first Production PIC Programmer running in Windows and under US$ 20.00. ========================================================
