Hi there, I'm wandering if something is happened with my registration at jal_developers list or is just a summer time ? I don't remember, there is pragma...
Interesting solution. Thanks for posting. BTW, I was using something similar, but without retlw0 at the end of a specific string. I was numbering the sentence...

hello i have just started progrmming in assembly of pic . i wrote a simple program for pic16f84a running at 4mhz . it has got a timer routine which runs for...
Hi Is it because your main routine continually calls init which resets the timer ? This is a bit off topic as this is a jal forum. Best Regards Martin R Dare ...
hi sorry for posting the message in JAL list...but as a beginner i was not getting the right place to ask this question...anyways i also got jal compiler but i...
Hi Nisheeth You seem to have a fundamental misunderstanding about how Timer0 operates. All pic timers operate in the background so other program execution can...

Hi Vasile, At least for me it's summer time, it's dificult not to be at beach taking a swim in these hot days (35~40ºC). ;-) I don't have the sources now...
... This sets TMR0 prescaler to 256, right? Taking this into account your led blinks not after 1sec but after 256sec (4min 16sec). You probably were not...

Hi Josef I thought you were good at this :-). His Pic is running at 4MHz. Thats 1 instruction per Microsecond. With the prescaler at 256, thats 256...
... Like in the hell :-) But the calculation is correct and the program is designed OK (omitting the prescaler) - it waits for 250 counts of timer0, then...

Hi Joseph It never occurred to me that he would be polling the timer value to count. I guess thats why its best to preload the timer using the interrupt from...
... Not typical, but possible usage of TMR0. Or adjust the TMR0 value by some constant to get different periods. On the bigger chips the TMR1 + CCPx in special...

I need to generate a pour shape (10%...20% distorsions?) sinusoidal signal with fixed amplitude and variable frequency from 1 to 20 KHz. There are two basic...

Thank you everyone for pointing how to solve the problem of sinusoidal signal generation using PIC microcontroller. I will try to sintetize yours valuable...
Hi Vasile To generate sine waves over a large frequency range is tricky. If you use a filter it only works well over a small range of freqencies. Best way I...
