serial port program

[falcon _bd]

 HELP ME !!!
I need some sample code in pic basic. I want to save my data  coming from serial port in pic MCU. Send me some sample code  using  inbuffer   and  out buffer. what is the maximum size of the buffer ??

hello, you must to use serin and serout functions

[babatundeawe]

try and give some more details where.

like where are saving it to. the internal eeprom or external
what is the baud rate. where are u sending it from. try and expanciate more on this.

Hi;
acually there is no hardware buffer for serial communication, it is only one byte, but still you can create your own sofware buffer and make as long as your free RAM permits.

Code:

rs232t var PortA.5      'TXD to GSM-phone
rs232r var PortA.4      'RXD from GSM-phone
Baud  con 84             '9600,8,N,1 (true, driven)

SerOut2 rs232t,Baud,["AT",13]
SerIn2 rs232r,Baud,500,Conect_Error,[wait("OK")]

----------------------------------------------------

with this code I have to wait for ' OK '
when I get the ' OK ' program go to the next line.
But I need  to save the 'OK ' in ram.
AT + CMGR =1 , with this command i want to save the whole sms in my ram.
what should  i do for that.
I need the sample code.

have a look at: http://www.melabs.com/resources/samples.htm
try the examples and pick out and mix the code that fit your needs.

You need to do some experimenting of your own if you want to learn..

Among many things you have to decide where to store your string of characters.
Make variables, arrays, subroutines for collecting character by character to put in the array.

I see some beginning of such code and also that you thought about having a ram for storage.

That is good but it also involves a routine for handling writing and reading the ram usually via i2c etc.

Good luck with your experimenting.

from proton 16f didnt support string, but u may use
Dim SerString[12] As Byte     ' Create a 12-byte array. to store ur recived byte.
SerIn Rx, 84,[SKIP 10,Str SerString\11]        ' Fill the array with received data. skip 10 byte first and recived upto 11 byte.

Code:

rs232t var PortA.5      'TXD to GSM-phone
rs232r var PortA.4      'RXD from GSM-phone
Baud  con 84             '9600,8,N,1 (true, driven)

SerOut2 rs232t,Baud,["AT",13]
SerIn2 rs232r,Baud,500,Conect_Error,[wait("OK")]

is very easy.. look for samples INSIDE.. PROTON the example SER_BUFFER.BAS..... and shazamm...!!!   good look!! woking for interupt and drive the buffers..is ok
