I need a code to store data in a PIC32 flas memory. Thanks a lot. Regards.

Dear Sir,
EUSART interrupt, I have written below lines
INTCON.GIE = 1;
INTCON.PEIE = 1;
PIR1.RC1IF = 1;
PIE1.RC1IE = 1 ;
But still EUSART interrupt does not work. U have any idea. Also may my mistake be in project setup

hi i wana use a MMC card. i hve the impression that the buffer is overfloding.
could someone check the code and tell me what i did wrong....
Code:
void sd_card_init()
{
// Initialisiere SPI für MMC Zugriff
SPI2_Init_Advanced(_SPI_MASTER, _SPI_8_BIT, 64, _SPI_SS_DISABLE, _SPI_DATA_SAMPLE_MIDDLE, _SPI_CLK_IDLE_HIGH, _SPI_ACTIVE_2_IDLE);
Delay_ms(10);
// Initialize MMC
if (!Mmc_Fat_Init())
{
// Falls MMC Init nicht i.O. ist SPI schneller initialisieren.
SPI2_Init_Advanced(_SPI_MASTER, _SPI_8_BIT, 4, _SPI_SS_DISABLE, _SPI_DATA_SAMPLE_MIDDLE, _SPI_CLK_IDLE_HIGH, _SPI_ACTIVE_2_IDLE);
}
}
void sd_card_read()
{
int zi = 0, zb = 0, zc = 0 ,zd = 0; // Schlaufenzähler
Mmc_Fat_Assign("config.txt", 0); //File config.txt öffnen
Mmc_Fat_Reset(&size); //grösse des Files auslesen und in size speichern
//File Auslesen und in buffer schreiben
for (zi = 1; zi <= size; zi++)
{
Mmc_Fat_Read(&buffer[0]);
//Wenn ein "-" (ASCII Code 45)
if (buffer[0] == 45)
{
zb = 0;
//Hier wird eine Zeile eingelesen (bis zum nächsten CR ASCII 13)
//oder 200 Zeichen eingelesen wurden
while (buffer [zb] != 13)
{
zb++;
Mmc_Fat_Read(&buffer[zb]);
if (zb == 200) break;
}
//Die ersten 4 Bytes des buffer werden in das Kommandobyte kopiert
zc = 0; //Schlaufenzähler auf 0 setzen
while (zc != 4) //Schlaufe um 4 bytes zu lesen
{
buffer_kdo[zc] = buffer[zc+1];
zc++;
}
//Byte 6 bis Byte 26 werden in buffer_ebene gespeichert
zd = 0; //Schlaufenzähler auf 0 setzen
while (zd != 20) //Schlaufe um 20 bytes zu lesen
{
buffer_ebene[zd] = buffer[zd+6];
zd++;
}
fill_vars();
}
}
}
void fill_vars()
{
//In dieser Funktion wird ein gefülltes Kommandobyte und Ebenenbyte
//vom Puffer in die entsprechende Variable ebenen_bez abgefüllt
//
//Funktionsinterne Variablendeklaration
int ebene_einer = 0 , ebene_zehner=0, ebene_total =0; //Ebenen Vraiablen
int ia = 0, i=0; //Schlaufen Variablen
//oder Ebenen Text
if (buffer_kdo[0] != 'E') return;
if (buffer_kdo[1] == 'B')
{
ebene_einer = buffer_kdo[3]-48;
ebene_zehner = buffer_kdo[2]-48;
ebene_total = (ebene_zehner * 10) + ebene_einer;
//4 Bytes Ebenentext in entsprechendes Array abfüllen
while (ia != 5)
{
ebenen_bez [ebene_total] [ia] = buffer[ia+6];
ia++;
}
}
//Ebenen Text in Array kopieren
ia = 0;
if (buffer_kdo[1] == 'T')
{
ebene_einer = buffer_kdo[3]-48;
ebene_zehner = buffer_kdo[2]-48;
ebene_total = (ebene_zehner * 10) + ebene_einer;
//Bytes Ebenentext in entsprechendes Array abfüllen
while (ia != 28)
{
ebenen_text [ebene_total] [ia] = buffer[ia+6];
ia++;
}
}
for (i = 0; i <= 128; i++)
{
buffer[i] = 0;
}
}
thanks

Hello.I use the instruction ;[ T6963C_txtFill(0);//Clear current text panel ] to make a page and to make 20 pages I write that instruction at the first and top of each page.But I think that is not a corrected way[on the basis of paging in T6963C GLCD].
Would you please tell me about the meaning of paging in T6963C GLCD and how can I make 20 different pages by T6963C GLCD?
Thanks,

Hello.I want to write an interrupt so that at every 5 seconds goes to one of the 3 different
labels in my Main program and runs all instructions followed by each labels
and after run the label3 back again to the label1 and repeat all those
labels endlessly,that is;
.........
........... //*** My circuit specifications; PIC18F8722,XTAL=20MHZ.
..........
void interrupt(){ // 5 seconds interrupt.
????? //At each 5 seconds just goes and runs
//one of labels and do the other one then
//reapeat those again and again,endlessly.
}//~
void main(){
.............
Label1:
instruction1;
instruction2;
instruction3;
.......
Label2:
instructionx1;
instructionx2;
instructionx3;
.......
Label3:
instructiony1;
instructiony2;
instructiony3;
.......
}//~!
Would you please help me to write that interrupt?
Thanks,
