Any good steps for learning SD card interfacing programming ?
I'm afraid I got error compiling when I copy exactly code from MikroC library example : MMC.
Purpose for this design : Want collect data from serial RS232 then stored as text file then read it by sd card reader (PC).
So initially I want learn how to learn read and write

You can interface SD card with PIC controller on SPI line.
And dont be lazy, search for it,
How can you directly ask for code.??
After using SPI communication, if you have any problem then post a topic.

With this webserver we can control peripherals from the Internet and see sensor data (1wire temperature sensors,...) from anywhere in the world.

can i connect a PIC16F877A to MMC? I am using HIGH TECH C compiler. Could u help me....
I have never used a PIC. However, if I had to, I would verify that:
- The supply power is compatible;
- It has a SPI bus or at least 4 unused GPIO pins to emulate SPI.
Then MMC or SD will connect without any trouble.

I would think power supply issues like ripples, noises or oscillations are the first thing one would check if the circuit is behaving intermittently.
When you send CMD0 command to place the SD card into SPI mode, you have to make sure it is placed in that mode by checking for the 0x01 response.
At end of each command, dis-select SD card (...)
