HI , I SEARCH FOR DEVELOPER THAT CAN BUILD FOR ME AN APPLICATION ON EASYPIC V7 THAT HAVE VIDEO IN HDMI AND VIDEO OUT HDMI , THE APPLICATION HAVE TO SHOW IN TV HDMI THE SIGNAL CONNECTED IN VIDEO IN PORT AND EVRY 3 MINUTES RESIZE THE SCREEN AND SHOW VIDEO SIGNAL + ONE ADV IMAGE . THE IMAGE WILL BE TAKE FOM A REMOTE SERVER .
PLEASE I HAVE LITTLE TIME IF YOU THINK THAT IIS POSSIBLE DEVELOP FOR MI THIS CONTACT ME
AND SEND ME YOUR BEST QUOTATION

im just starting to learn programming i need code to TO PROGRAMM pic 16f887 for 8 n/o & 8n/c inputs with a common output
thankx

the project uses PIC 16F887 and I'm programming using MPLAB IDE low level assembly language. the microcontroller should be able to detect a change in frequency on an external pulse train and count the number of times the train changes frequency in a five minute period. the train has a resonant frequency of about 80kHz which the microcontroller can determine on just after start-up (after a delay of one minute). thereafter the train changes by about plus or minus 5kHz and after every change it returns to its resonant frequency.

Hello,
I want to use FAT32 library (download libstock PIC32) but visual tft supported fat16 library.(not FAT32) What do I need to change? and or visual tft supports fat32
please help me?
how to use global definations (fat 16)
// MMC/SD Connections
sbit Mmc_Chip_Select at LATD12_bit;
sbit Mmc_Chip_Select_Direction at TRISD12_bit;
// end of MMC/SD
// TFT Get Data globals
char Ext_Data_Buffer[512];
unsigned long currentSector = -1, res_file_size;
// end of TFT Get Data
void Init_Ext_Mem() {
//--- set up SPI for the file read
PPS_Mapping(104, _OUTPUT, _SDO3);
PPS_Mapping(98, _INPUT, _SDI3);
PPS_Mapping(79, _OUTPUT, _SCK3OUT);
// Initialize SPI
SPI3_Init_Advanced(_SPI_MASTER, _SPI_8_BIT, _SPI_PRESCALE_SEC_4, _SPI_PRESCALE_PRI_16,
_SPI_SS_DISABLE, _SPI_DATA_SAMPLE_END, _SPI_CLK_IDLE_HIGH, _SPI_ACTIVE_2_IDLE);
Delay_ms(10);
// Initialize MMC
if (!Mmc_Fat_Init()) {
// Reinitialize SPI at higher speed
SPI3_Init_Advanced(_SPI_MASTER, _SPI_8_BIT, _SPI_PRESCALE_SEC_2, _SPI_PRESCALE_PRI_16,
_SPI_SS_DISABLE, _SPI_DATA_SAMPLE_END, _SPI_CLK_IDLE_HIGH, _SPI_ACTIVE_2_IDLE);
// Open resource file for read
Mmc_Fat_Assign("%FILE_NAME", 0);
Mmc_Fat_Reset(&res_file_size);
}
}
char* TFT_Get_Data(unsigned long offset, unsigned int count, unsigned int *num) {
unsigned long start_sector;
unsigned int pos;
start_sector = Mmc_Get_File_Write_Sector() + offset/512;
pos = (unsigned long)offset%512;
if(start_sector == currentSector+1) {
Mmc_Multi_Read_Sector(Ext_Data_Buffer);
currentSector = start_sector;
} else if (start_sector != currentSector) {
if(currentSector != -1)
Mmc_Multi_Read_Stop();
Mmc_Multi_Read_Start(start_sector);
Mmc_Multi_Read_Sector(Ext_Data_Buffer);
currentSector = start_sector;
}
if(count>512-pos)
*num = 512-pos;
else
*num = count;
return Ext_Data_Buffer+pos;
}

The A to D converter from the the help libraries (pic basic pro on easy pic v7) will generated a binary number and light up the led's on the selected port.when the input pot is turned to simulate an analogue signal. I need help to get that number's equivalent decimal to be displayed on the segment seven displays. As an example take that binary number, and displays the decimal equivalent on the 4 segment 7 displays. As an example, binary number 111 would display a 7 , 1000 would be 8 etc etc.
Eventually, I would like to show the thermistor output (after appropriate scaling) as a temperature readout.
Please point me in the right directions.
