Problem in thesis..GSM module and analyzing SMS

[Kaizer03]

Bka meron naman poh kayung maisasuggest na pamalit sa 7805 5v voltage regulator kasi poh mukang kulang yung current rating niya para suplayan yung 1 namen na pic16f84a na may nakakabit na dalawang 5v relay sa output nia and 1 din pohng pic16f877a na my nakakabit na 4 5v relay and GSM modem poh...kahit poh konten circuit manipulation para mapataas yung output current ng voltage regulator khit mga 3A poh sana...dbah poh mas okei na na mataas yung output current pra ndi maxadong maginit ung regulator...sana poh matulungan nio kame...salamat!!

yeah check mo yung sinabe ni tita rdp, yung 'Current Boost Regulator' meron din sa ibang datashet pero masmaganda yung sa national..

kung gusto mo  ng component na 5V regulator na 3A, you can check 78T05, sa farnell at rs ata ako nakakita nito last year.. pero syempre mas mahal ito=)

ganun poh ba..?nasa magkanp nmn poh kaya yung mahal na yun??nasa 300 poh ba??Salamat...

[Kaizer03]

di naman =)

Salamat!..try ko tumingin sa deeco kung meron cla kpg ala n talaga akong makita sa malapit punta nlang ako sa farnell sa makati poh dibah?..Point for your kindness..salamat ulet!..

[louis26]

mga sir patulong poh ulet kasi poh ngttry aqng magprogram ngaun..gamit ko poh ung less than 200 pesos programmer galing dito sa forum na to..gamit ko pong software is icprog..while programming poh okei naman sya alang error gang mtapos ung programming..taz after programming nireread ko poh sya okei naman poh preho lang xa na iniupload ko na hex file..kea lang poh kapag tinetest ko na xa ndi gumagana yung blinker ko poh taz kapag narreread poh ako ulet iba na yung laman nia or should i say na may mga part na bumalik sa pgging 3fff nia..taz nagvolt meter poh aq sa mclr 12v lang poh sya upon programming..okei lang poh ba un na 12v??pic16f877a poh yung pinoprogram ko poh..help naman poh...

[louis26]

okey na poh xa.. mali pla yung binigay saken na resistor imbis na 10k,1k yung binigay sken taz kulang lang pla ako ng decoupling capacitor..hehe liit lang na bgay pinahirapan ako ng husto..hirap tlga pag newbie.. taz kelangan pla naka high ang mclr pra magblink ang led kpg ala nun ndi pla magbiblink..ala kasi akong kinoconnect dun kpag ngsasimulate ako sa proteus..naguluhan 2loy ako..sabihin ko na din sa forum na eto bka meron din katulad ko na medyo engeng eh para ndi nama :Pn mahirapan..hehehe

[mini_mouse ^_^]

...hello po,may project din po kami na i-turn on andoff ung device through text... tanong kolang if successful ung ptoject mo...nagwork na kasi ung samin kaso lang, nasira... tinutroubleshoot pa...

[maldihtah13]

Ano naging problema?

[ΔЅịMø]

kasama ko poh c stepipai... nag work na poh xa, pro after 4 trials, di na nag-wprk... di namin alam kung wat ang problema.. may idea poh ba d2 on how to put a received msg comming from the gsm to an array?... pra poh ma compare namin... may code na poh kmi kya lang, di na nag wowork... thesis project poh namin..

yan na poh mga sir.. bali, mag sesend lang ako nang DEVICE1OFF na word sa GSM ko, mag rereply xa as "Programming Successful"...

[maldihtah13]

It is better if you'll use PDU mode in decoding the message since the location of the message in text mode varies.

ex.

upon first reading the gsm will give you
+CMGR: "REC UNREAD","+639217640883",,"04/09/16,11:23:06+12"CRLFMESSAGE V1CRLFCRLFOKCRLF###..

after reading it again
+CMGR: "REC READ","+639217640883",,"04/09/16,11:23:06+12"CRLFMESSAGE V1CRLFCRLFOKCRLF###..

CR=Carriage Return
LF=Line feed

[mini_mouse ^_^]

...ah, dapat pala PDU mode ang gagamitin namin... ................ tnx poh...


@louis26:

kamusta na po ung project nyo? working na ba talaga?

ahh.. oki poh sir.... in PDU mode poh, pwde ko na ma parse ung msg? ung project poh kc namin sir is about home automation...
ganito poh ung process sir:

SMS message -------> array --------> compare
if the msg is equal to "DEVICE1OFF", then i-off nang mcu ung device1 sir tpos send xa nang confirmation msg na "Device 1 has successfully turned off".

check nyo to http://www.electronicslab.ph/forum/index.php/topic,13813.80.html

post 92 & 93 ... it is written in Proton pero andon ang comparison ng PDU mode
