kuya, di po tuloy na compile... i looked at the library files (headers files), P1_0 talga...

here, i'm posting the whole header file:

oo nga 'no...

RC51 compiler pala yung nasa isip ko...

[beginner wan]

......

sis, panay ang error ng M-IDE ko... access violation daw. eto sampol:


may special setup ka pa bang ginagawa?

isa pa nga pala, yung header files di automatic yung paghanap ng IDE. instead ganito pa ang ginagawa ko:
#include "C:\MIDE\sdcc\include\mcs51\at89x051.h"

yung error sir marce, galing yan dun sa latest na MIDE.exe. parang bug ata yan. lumalabas sakin yan pag humahaba yung comments ko sa code ko.. try mo sir marce download yung mas lumang MIDE.exe, mas ok gamitin yun..

dun naman sa header files, automatic naman sakin yan, baka dapat nasa tamang folder.. diko lang alam kung saan folder dapat, kasi matagal nako walang C eh.. 

[beginner wan]

oo sis... umaandara yun. RB0 ^= 1;

timer naman... ewan ko lang kung sa proteus. pero eto yung calculation ko. sa 12Mhz, may 1us each increment. dun sa posted code code ko, 16-bits ang intented na timer. so 1us x 65536 = 65.536ms ang bawat overflow. therefore kailangan ko ng 15-16 overflows to make a 1 second... tama ba sis?

so ganito ang ginawa ko...

Code: [Select]

#define OVERFLOW_1S 15
while(1)
{
if(TF0)
{
TF0 = 0;
overflows++;
if (overflows >= OVERFLOW_1S)
{
overflows = 0;
i++;
if (i>=8) i = 0;
P1 = MAP[i];
}
}
}

pero yung outcome, mabilis pa din... weirdly(or talagang di pa ako sanay... hehehe) kung ilagay ko OVERFLOW_1S = 150, parang tamang tama yung bilis.

......................

noted sir... i am struggling last night to make my M-IDE work. it always give a "runtime error". ewan ko po ngayong nagrestart na ako...

sir marce, may suggestion po ako dun sa timer mo. try nyo nalang po magload ng 0xFFFF (which is max value ng 16-bit timer) - 10,000 = 0xD8EF sa timer registers nyo.. para sir saktong 10mSeconds yung inyong interrupt at approximately walang butal..

eto po pala sample ng timer interrupt routine ko in assembly.. 16-bit timer using timer0 to count upto 24 hours..

Code: [Select]

dun naman sir sa run time error, i think may problem po dyan yung location ng SDCC files nyo. maka-iba po siguro yung pwesto ng SDCC nyo sa nakalagay sa preferences nyo..

[insomartin]

i still can't understand.

[leoren_tm]

hi, sa keil try using
#include <reg51.h>

sbit MY_PIN = P1^0;

MY_PIN~=MY_PIN;
MY_Delay(100);

[marcelino]

@wan, i think, tama sa location nga ng SDCC.

tapos prior kasi ng pag-install ko ng MIDE, nag-install na din ako ng SDCC... heheh
uninstall ko lahat siguro, then install yung MIDE with SDCC.

[rdpzycho]

'yan sumagot na si wan.

[beginner wan]

 

[marcelino]

thanks wan! pogi mo...

ok na ang compiler ko... nalito ng dalawa ang nakainstall na SDCC. heheh

[beginner wan]

tnx sir marce! mabuti at ok na compiler mo.. 

[clarkent]

mga sirs, plano ko po sanang gamitin yung ds89c450 ko from maxim. it has 6 external interrupts (ex0-ex5),i'm using mide pero ang problem po ay ang 8052 ng mide meron lang 2 external interrupts sa register file, pano po kaya magagamit yung 6 EXs?TIA

[ATE]

^meron ka bang copy ng SFRs ng ds89c450?

[ATE]

^may nakita ako sa datasheet pero di ako sure

ideclare mo yung SFR sa main program mo or pwede ka ring gumawa ng sarili mong header file

how to declare SFR:
sfr at 0xE8 EIE;
sfr at 0x91 EXIF;

sa mga bits naman:
sbit at 0xE8 EX2;
sbit at 0cE9 EX3;
sbit at 0cEA EX4;
sbit at 0cEB EX5;

(pakiverify na lang kung tama)

yung address ng special function register (SFR) is 0xE8... yung name ng SFR na naghahandle ng mga external interrupts 2 to 5 is EIE...

yung EXIF naman na located sa 0x91, yun ata yung sa mga flags...

yung
EX2 nasa bit 0 ng EIE
EX3 bit1
EX3 bit2
EX4 bit3
EX5 bit4

yung mga flags naman
IE2 bit4 ng IXIF
IE3 bit5
IE4 bit6
IE5 bit7

kung di ako nagkakamali, same lang sila nung sa ex0 at ex1 sa pagaccess...

[rdpzycho]

sa Maxim ata may headers. pero gumawa ako dati. medyo nakakatamad. hehehe.

[clarkent]

^diko mahanap yung mga header files.hehe

[ATE]

^may nakita ako sa datasheet pero di ako sure

nagkamali ata ako sa mga bits...pakicorrect na lang 

[leoren_tm]

check mo sa keil.com may mga collection na header files,change ka nalng kunti if not supported un bit naming nila

[clarkent]

i found out that MIDE has ds89c420, tiningnan ko yung laman ng file, nandun na yung mga sfrs na hinahanap ko. ds89c420.mcu ung file.
