<br>
<br>zdravim,<br>
<br><br>
<br>skusam nanecisto (v simulatore) pic16f877a a prekladac od hi-techu v lite<br>
<br>mode<br>
<br><br>
<br>mam z toho ale divne pocity, kod je :<br>
<br><br>
<br>-------------------------<br>
<br>#include <br>
<br><br>
<br>__CONFIG(HS & WDTDIS & PWRTDIS & BORDIS & UNPROTECT);<br>
<br><br>
<br>volatile unsigned char tim128us;<br>
<br>unsigned char tim1ms;<br>
<br><br>
<br>void timer_init(void);<br>
<br><br>
<br>void main(void)<br>
<br>{<br>
<br> timer_init();<br>
<br> ei();<br>
<br> while(1)<br>
<br> {<br>
<br>// di();<br>
<br> if (tim128us >=4 )<br>
<br> {<br>
<br> tim1ms++;<br>
<br> tim128us = 0;<br>
<br> }<br>
<br>// ei();<br>
<br><br>
<br> }<br>
<br>}<br>
<br><br>
<br>void interrupt isr(void)<br>
<br>{<br>
<br> if (TMR1IE && TMR1IF) <br>
<br> {<br>
<br> TMR1IF=0;<br>
<br> tim128us++;<br>
<br> }<br>
<br><br>
<br>}<br>
<br>//timer1<br>
<br>void timer_init(void)<br>
<br>{<br>
<br>TMR1CS = 0;<br>
<br>TMR1ON = 1;<br>
<br>T1OSCEN = 1;<br>
<br><br>
<br>TMR1IE = 1; //?<br>
<br><br>
<br>PIE1 = 0x1;<br>
<br>}<br>
<br>-------------------<br>
<br><br>
<br><br>
<br>1. nejde to - myslim prerusenie od casovaca, simulator niukdy neskoci do<br>
<br>isr, aj ked counter pretecie<br>
<br><br>
<br>2. zapis TMR1IE = 1; nenastavi bit PIE1 registri ale sposobi 1 v PIR1<br>
<br><br>
<br>Robim nieco principialne zle? <br>
<br><br>
<br>vdaka za pripadne nakopnutie, p.rosko<br>
