Thank you for your reply. Does that mean that I could think of block number one being from address 0 through 511 and block number two from address 512 to 1024?

Also, I was hoping that somebody cou ...

Also, I am using PIC18f4520 and a 2GB SanDisk SD Card.

Hi Everyone,

I've been successful in modifying ex_mmcsd.c file to write data to memory location 0x1000 and 0x1001 and displaying it on a 16x2 LCD display.

My goal is to set aside each block (51 ...

i've noticed that many people use hyperterminal to test their codes on their pics. I've never used it before, can anybody direct me into setting this up so that i could make my life easier Smile

thanks!

Does anybody have an idea? I've modified to work this way:

void main()
{
char opt_buffer[255];
strcpy(opt_buffer, "test.txt");

fat_init();
/ ...

Hello,

I've taken a look at the ex_fat.c file to see if I'd be able to create a file into my SD Card using PIC18f4550. Here is my main code below:

void main()
{
char opt_buffer ...

Again, thanks for your reply.

So, from this, I am getting that if I wanted to make one file and write and append to it, the PIC MCU wouldn't be able to read the data. I am trying to log weight data ...

I read the note that says:
// NOTE For faster writing or appending for an application such as a logger,
// uncomment #FAST_FAT below. This will make the FAT library assume

I am supplying the pic with 3.3 volts to interface with SD card through voltage regulator. Is it okay if I connect the wires from ICD-U40 directly into the PIC MCU without having to reduce voltage lev ...

Thank you, I reinstalled for the 7th time, and it's starting to work correctly. I am not sure what the problem was. Thank you for your help.

thank you for your input. I tried that and i still get build failed

Executing: "C:\Program Files (x86)\PICC\Ccsc.exe" +FM "..\simplecode.c" #__DEBUG=true +ICD +DF +LN +T +A +M + ...

Hello Everyone,

I changed the ex_fat.c for 18f4550 by making the following changes:

#define MMCSD_PIN_SCL PIN_B1 //o used to be C3
#define MMCSD_PIN_SDI PIN_B0 //i used to be C4
#de ...

My ccs c compiler simply stopped compiling. I am not even sure what I did, but the build keeps failing even with codes that have compiled before. This is what I get with no matter what codes I use.
