The instruction cycle time with an 8-mhz clock is 500-nsecs... Since the TMR2 prescaler and postscaler are both set to 1, TMR2 is incrementing every 500-nsec 'tick', and so, 208 such 'ticks' (104-usecs) will have elapsed when the TMR2 and PR2 register match and generate an interrupt...

The 104-usec value is the bit-to-bit clock period for 9600 baud (1/9600=.000104166)...

HELLo

It is a pretty good code by the looks of it.. However I am new to assembly and I quite dont understand what _tx stand for and what u mean when u sate in the begining that "_tx is the bit used for transmit data, must be set as output"

movlw minVal
subwf _x, W
btfss STATUS, C
subwf _x, F
It should work for max limit as well,
just change to btfsc instead.

    I am building a lamp dimmer for household use. The object is useing a phototransistor at +5v logic (built) as the analog input to my PIC16F877. I want to translate the phototransistor voltage to timer 1, and use that as an off time related to triac triggering on the ouput. Zero crossing will be used to begin the timer. After the timer counts out, the triac will be fired and the remaining AC alteration will be output to the light. Any suggestions for PIC programming?...HELP!!!

    I want a schematic 3 channel receiver infra red by using any remote control(tv\vcr\sat\...) and contain pic12c508 and 24cxx eeprom and it can store any type of remote control to use it as following:
    1) we press any button in the remote control and direct it toward receiver unit(our project) and in the same moment we switch on the receiver unit
    2) press 3 buttons (example:1 2 3) then the unit is ready to be used
    3) when we press  1 or 2 or 3 the relays will work(e.g: relay1 will work by button 1 and switch off by button 1 too)
    4) we can reprogram the unit by other remote control
    
    PLEASE,give me the code(asm or hex file) for this project
