uy kailangan ng disassembler... meron ka bang magandang disassembler?

pag nadisassembled natin yan at least magkakameron tayo ng idea how it works

Pwede naman gumawa ah lalo na sa dilim

pinakamahirap hanapin yung 7.3728 MHz na crystal, ginamitan ko dati ng 8MHz pero ayaw gumana.

last time ko gumamit nyan is with this...

meron pa akong 3pcs xtal nyan..di ko lang alam if saan ko natambak...

Ini-improve ko pa yung gsm code ko sa PIC ... tapos ipoport ko na dito sa atmega8515. Meron din ako nadownload na c source code for FBUS kaya lang I dont think its worth it to develop anymore dahil pahirap na ng pahirap makahanap ng good condition and working 3310.

sa 3310/3315/3410/3350 dumabaha pa dito sakin sis...hehehe...

Eh di gawin mo na sis itong epe sms controller.

MC34064P-5 under-voltage sensor - actually not needed kung atmega8515 ang gagamitin pero may available nito sa deeco. Just enable BOD sa atmega8515.

AT90S8515-8 or ATMega8515-16 microcontroller (40 pin) - 125 petot sa Alexan

ULN2803 Darlington transistor array - meron din sa Alexan, nakalimutan ko na presyo

220μH ferrite choke - kinuha ko yung inductor from some generic 50 petot car cellphone charger na gumagamit ng mc34063 kasi karamihan ng design na nakikita na 12Vdc source na step down dc-dc converter uses 220uH inductor. Pwede din naman lm317 na lang ang gamitin or huwag na lang gamitin.

7.3728MHz crystal - meron ka na pala nito so OK na OK

pweding pahingi nyan sis?.. pag eexperimentohan ko lang.. madali kasi ang buhay pag sa AT commands... hihi

pag natapos ko no problem .... on and off kasi yung pag gawa eh, masyado maiksi attention span ko, mabilis ma-divert sa ibang projects.

Kaya ko naisip gumawa alternative f/w kasi gusto ko gawan ng sms functionality yung neSS2 and I noticed na pin to pin compatible ang 8515 sa 89s52. Medyo napabayaan lang at nadivert yung attention ko sa ibang project.

This is nice Sir Alyas, 1diyTEAM would be glad to see your masterpiece - the GSM module working on NE2ss Educational Learning Trainer Board.

It is right, ATmega8515 or ATmega612 is pin to pin compatible with the AT89S52, what is actually needed to change on the hardware of NE2ss is the Reset. AVR is active low, 8051 is active high.

Good luck and more power.

I mean yung FBUS protocol po ang hihingin ko di bale na yang AT commands based..

You will need an mcu with lots of RAM otherwise simple on and off application lang magagawa mo. FBUS will eat a lot more RAM than using AT commands and if you will check the net, you will find that most fbus projects uses higher end mcus (faster and more RAM).

Google mo lang n6110.c, it's fbus driver for the pc but pwedeng i-port to an mcu with big amount of RAM.
