Guys I have studied lots of stuff regarding Nokia FBUS ver1.The problem is the old phones like 3310/6210 no longer available even second hand.
Does anybody have FBUS version3 documents which supports with NOKIA 1200?
Is there a big difference between Nokia FBUS ver3 & FBUS Ver1?
fbus at commands
Thanks mate I understood little bit.
I have some problems.Now phones like 3310 are not available.What are the other phones supporting FBUS which is commonly available?
The other problem is when I send a sample frame (get H/W & S/W version) to phone the phone will reply with...
fbus commands
I'm going to interface a PIC with nokia 3310.
Can anybody tell me whats the relationship between FBUS & AT Commands?
There's another thing called PDU & Text format I'm confused with those words.
Thanks
how to connect 74hc595 schematic
Hi guys can you recommend me what is the best shift register from those two when designing a long LED matrix?
74HC164 or 74HC595 ?
I made one with 74HC164 but the display is not smooth.
Hi you all know a CDMA phone has an RS232 port.
Does anybody know a method to access the phone via this serial port?
I mean dialing a particular number,Answering etc............via its serial port?
problema de vpp pickit 2
OK thanks for the idea.
I mostly programing the pics with MCLR = off & INTOSC to enabled.So to the lite version I need to add some additional transistors.Also it must drive through from pins 24 & 25.Isn't it?
blueroomelectronics pickit2 lite
I mean the PICKIT2 Lite version.Not the full version.
In lite version the pin 24 & 25 not used.In another design that pins directing to some transistors to control VPP or something.
But in the lite version these pins 24 & 25 are free. Will it ok to program...
pickit2 clone
Can the PICKIT2 Clone program the chips like 12F675/629 etc that needs VPP control?
Does the PICKIT2 Clone cotrol VPP?
Here is the one I'm going to build.

Hi!
I need to connect a small audio circuit to cell phones MIC input so I can hear the audio signal through the phone while I'm in a call.
The audio circuit that it needs output a beep or a note (not a melody).So when I give power to the circuit I can hear that beep via cell phone.
Does...
Oh no then my project unsuccessful.
I need to send any sound out to the headset while I'm in a call. The call will pick up automatically thats ok. But i need to make a sound (even a key press sound) out to the headset.
This must do without using FBUS/MBUS.
Hi is it possible to do pulse dialing from the headset (port) of a mobile phone?
From a landline I know how to do pulse dialing I want to know is it possible to do from a mobile phone?
I see now its very useful when implement something without micro-controllers.Thanks for that hint.
Ok I'm going to tie both the inputs together.
But last night got a problem when B = high (A floating) the LEDs counting one by one thats ok.
when A= high (B floating) the LEDs wont count.
74hct164 clock
Hi thanks for the reply.
You are totally correct last night I make an experiment.
I cleared everything that you described.
But I wonder why it needs two inputs A & B? One input is more than enough.?
Better tie both A & B together & give inputs.
74hct164
Hi I need to drive 16 LEDs from 2 shift registers 74HCT164.
The inputs to shift registers I'm giving from a 8 pin micro controller.
The problem is I don't know what logic to give to serial inputs (A & B) in the shift register?
I know only to give clocks.
