pwede ka gumamit ng PICKIT2 or pickit3.. nasa 2k ata... pwede rin JDM (serial) programmer (mas mura)...

dati may benta dito (Elab) specifically for students.. nasa 1k+ ang price nun.. not sure if meron pa available...

firmware done by sir zerowing, actual hardware/debugging done by me.. sure you can do it.. posted naman ang source code..

tnx po sir! kumpleto na po ba un sa 1k, tanong ko lang po, pwede po bang gamitin ung lcd scope sa pagtingin ng frequency ng transformer, flyback at deflection yoke ng tv?

with the current hardware setup(schema shown), it can SAFELY "See" voltage up to 5Vdc... if you want to "see" higher voltages, its advisable to use resistor voltage devider...

it can view 60Hz transformer freq also..

for flyback(w/c is High Freq ), it can NOT.. max freq is limited to 10KHz only..

question po, ano pa po pwedeng project using microcontroller.. naisip ko din po sana eh ung sms based,, automation po.. halimbawa pagaganahin ko ang isang appliances using sms

OFF TOPIC kana

better create a thread regarding your query... or you could do some searching dito sa forum, kindly use the SEARCH function... or better yet, browse ka sa mga threads dito related to PIC programming.. I m sure madami ka makikita.. some usefull, some useLESS

sorry sir!! newbie lang kasi ako.. hehe..

p®otocol · « **Reply #109 on:** January 07, 2011, 03:50:11 PM »

sir san po kaya ako mkkbli ng PIC18F452

... gus2 ko try i build sana... and san poh ako pde makabuy ng pickit2... pag may signal gen po n ggmitin need pa rin po ba ung adc??? o pde ko na idirect ung fgen or voltage dun sa ic input?... tinry ko ung code sa mplab nageerror xa ung mga basic lng na codes ung alam ko sa c programming...

sorry dami ko ask... hoping for your answers... thankz...

p®otocol · « **Reply #110 on:** January 07, 2011, 04:05:16 PM »

tska sir kung f ever may availble kau na nagawa na... can i buy it...

yellowmello · « **Reply #113 on:** January 18, 2011, 04:33:21 PM »

ok chief, kasi tinitignan ko ung mga zener tsaka un XTAL ba un malapit sa PIC? ala kasi sa schematic e... ptulong nmn po.. tnx

RaffT · « **Reply #114 on:** January 21, 2011, 06:38:22 PM »

post ko lang dito site ng PC signal gen na gamit for the test done:

yellowmello · « **Reply #115 on:** January 22, 2011, 05:12:01 PM »

chief anong value nung XTAL sa diagram? ung VGND tsak un Ground ba sa mga amplifiers pareho?

RaffT · « **Reply #116 on:** January 22, 2011, 05:28:00 PM »

20MHz..

GND is circuit ground.. Vgnd is VirtualGround used by the op-amp ckt // NOT the same

yellowmello · « **Reply #117 on:** January 23, 2011, 12:47:24 PM »

salamat chief.... we are trying this for our thesis project... pasensha na po kung may mga tnong pero paptulong sana ako sainu.pag may mga questions pa ako ask ko lng sainu chief ok lng?

yellowmello · « **Reply #118 on:** January 23, 2011, 11:03:07 PM »

questions lng chief.. ung 3.8 sa LCD supply nya right? pulsating DC? tapos ung signal gen di na po ba included sa ckt? - i ibang device na un tama sir?

yellowmello · « **Reply #119 on:** January 26, 2011, 09:56:20 AM »

sir, mejo kinakabahan na group mates ko, defense is within 1 week, mejo di ko makapa ung mga hidden circuit ng project, possible kaya sir kung pwd namin ma avail un proto nyo? and san po kaya namin kayo pwd ma contact?... pasensha na chief, sainyo kami nagpapatulong, ung teacher naman kasi namin di man lng kami turuan
