sir
meron ba kayong compilation ng assembly code (OP code) ng zilog/PIC microcontroller , pa share naman.
thanks

Hello po may sample po ba kayo ng serial programming sa pic16f877 sa assembly po, kasi po may ginawa ako sa simulator gumagana pero pag totoo na wala akong makita.

hingi naman po ng sample ung gumagana. ung kapag nagsend ako ng one from may vb6 prog eh.. mag aout ng one ung specific port.

please po...
thanks po...

ganyan talaga ang simulator , madaya kasi hindi real time ang simulation niyan.. kahit sinasabi ng proteus at iba pang simualtion software na rela time.. wala pa rin yan unless naload mo sa actual na microcontroller

solutions:
1. check the baud rate of your serial port
2. crystal oscillator mo pareho ba don sa nakaset sa simulation tool?
3. baka wala kang nakita kasi ang bilis ng refresh rate mo...

-hope these helpz

thanks po sige po check ko uli.

wala po bang paraan para macheck ko kung nakakareceive ung pic kahit ung mga voltage changes po. ung sa hypertherminal po ba, pagnagsend ako ng char na 1 send nya ba un as int na 1 then marereceive ng pic kahit nakabluetooth.

tanong ko po required po bang ibind ung bluetooth ng e-gizmo sa pc para magconnect? nagkakaproblema po ba sa ganun?

try to do on and off ng led, say kapag nag send ka ng character "A", mag on ang led, kapag "B" naman, mag off ang led.

i agree with sir glenjoy... isa sa mga best and simple techniques yan for checking UART reception ng MCU...

makikita nyo sa oscilloscope yung voltage changes pag nakareceive or nagtransmit kayo from PIC (RX and TX pin)... ano ang baud rate nyo?

Sa assembly mo ginawa yung serial routine? Baka may mali sa baud rate calculation mo? I would suggest magmigrate ka sa C kung ganyan na ang application mo.

ung baudrate po kasi sa pic may error kasi po ung ginagamit ko 9600, eh wala pong sakto sa pic ung meron lang eh 9615 so may error po. nakakaapekto po ba yun?

sa C po ba sakto sakto ang baudrate?

9615 is still acceptable for 9600 baud. Theoretically, the error should not exceed 1/2 bit time over the length of sending a byte. For 8-bits data+1 stop bit (total 10 bits including start bit), that is about 5% of the baud rate or 10,800 baud maximum.

However if you are sending a byte through a phone line, a slight baud rate error will make it prone to communications errors. But if you are communicating between to devices through a null modem cable, it should be no problem.

Programming in C will not solve a hardware problem.
