Hallo mikroe-Team,
I suppose that this problem is released by the WDT. The time of the restart amounts 17min (Watchdog Timer Postscaler 1:1048576). In my application is switched off of the WDT.
viele Grüße

Hallo mikroe-Team,
if a programme is loaded with the Bootloader in the Multimediaboard PIC32 MX7, carries out the MCU after approx. 20min one Reset and the loaded programme restarts. What do I make wrong?
best regards
Uwe

hi
i tried following code for 18F2550 (20MHz) with default configataion at time of creating project
void main()
{
PORTB = 0; // Initialize PORTC
TRISB = 0; // Configure PORTC as output
PORTC = 0; // set PORTC to 0
TRISC = 128;
TRISA = 0xFF;
UART1_Init(9600); // Initialize UART module at 9600 bps
PWM1_Init(1000);
Delay_ms(100); // Wait for UART module to stabilize
while(1)
{
.
.
.
.
.
}
compiler gives an error at either PWM1_init or UART_init
it comlipe either PWM or UART at a time
individualy PWM and UART works as usual
but when i tried at as above it dose not work pleas help me
i guess it may be problem with configuration only but i could not found

Hello there,
maybe someone can tell me where is my mistake when I calculate free clusters in FAT table.
I have read tons info about FAT16, but anyway something wrong in my code. I compare my results with results giving WinHex or simple Win. So my code :
.........
ptrInt = &DataBuffer[0x0B];
BytesPerSector = *ptrInt;
SectorsPerCluster = DataBuffer[0x0D];
ptrInt = &DataBuffer[0x0E];
ReservedSectors = *ptrInt;
NumberFats = DataBuffer[0x10];
ptrInt = &DataBuffer[0x16];
SectorsPerFat = *ptrInt;
ptrLong = &DataBuffer[0x20];
NumberSectors = *ptrLong;
ptrInt = &DataBuffer[0x1C];
HidenSectors = *ptrInt;
FirstFatSector = HidenSectors + ReservedSectors;
LastFatSector = FirstFatSector + SectorsperFat;
Root_Dir_Start = ReservedSectors + NumberFats * SectorsPerFat;
First_Data_Sector = Root_Dir_Start + 32;
Usable_Clusters = (NumberSectors - (First_Data_Sector + 1)) / SectorsPerCluster; // Total available clusters
Capacity = BytesPerSector * SectorsPerCluster * Usable_Clusters;
there any problems - formulas works great,
but there I'm stuck :
Sector = FirstFatSector;
freeClusters = 0;
while( Sector < LastFatSector )
{
Mmc_Read_Sector(Sector, DataBuffer);
for(i=0; i<256; i++) // i - FAT entries. 256 - in FAT any entry is 2 bytes long, so 512/2 = 256
{
if((DataBuffer [i*2]== 0x00) && (DataBuffer [(i*2)+ 1]== 0x00))
freeClusters++;
}
Sector++;
}
......
result ==> freeClusters = 61450 - a little to big!
but WinHex show me another value - 61243.
So I'll be deeply thankful

I am one of the biggest fan of MikroC for PIC.
But i am stuck in a problem..
Due to some reasons i can't use 4-bit mode LCD Code..
And That's why i need 8-Bit LCD Code..
Pls Help Me.. If Someone know how to do this..
