problematic array

[adrian]

I have a question on how to increment an array.

First the important stuff:
PCM 3.148
12F629

I have an array which I initialise thus:

Bonjour,

you can try this code

//----------------------------------------------------------------------------
// SPI I/O
//
#ifndef __SPI_IO__
#USE fast_io(c)
#define SPI_SO PIN_A5
#define SPI_SI PIN_A4
#define SPI_SCK PIN_E0
#endif // __SPI_IO__

//----------------------------------------------------------------------------
// Your DATA
//
#define ZERO 0x7E
#define ONE 0x0C
#define TWO 0xB6
#define THREE 0x9E
#define FOUR 0xCC
#define FIVE 0xDA
#define SIX 0xFA
#define SEVEN 0x0E
#define EIGHT 0xFE
#define NINE 0xDE

//LCD display
int digits[10] = {ZERO,ONE,TWO,THREE,FOUR,FIVE,SIX,SEVEN,EIGHT,NINE};

//----------------------------------------------------------------------------
// public :
// Function :Write_SPI
// Version :0.1
// Author :Alain
//
// Usage :write_SPI(Data)
//
// Arguments:BYTE Data Data to write
//
// Return :void
//
// Modify :void
//
// Shifts out on the falling edge of the clock.
//----------------------------------------------------------------------------
void write_SPI(BYTE Shift)
{
BYTE BitCnt = 8;
//--- Shifts out
do {
//--- Clock low
output_low(SPI_SCK);
//--- Bit = 1
if(Shift & 0x80)
output_high(SPI_SO);
//--- Bit = 0
else
output_low(SPI_SO);
Shift <<= 1;
//--- Clock high
output_high(SPI_SCK);
} while (--BitCnt);
}
#ifdef __TEST__
//----------------------------------------------------------------------------
void main(void)
{
int8 ByteCnt;
//--- Loop Test 1
for (ByteCnt = 0; ByteCnt < 10; ByteCnt++)
//--- Output the Current Byte
Write_SPI(digits[ByteCnt]);

//--- Loop Test2
ByteCnt = 0;
while (ByteCnt < 10)
//--- Output the Current Byte
Write_SPI(digits[ByteCnt++]);

//--- Loop Test3
ByteCnt = 0;
do {
//--- Output the Current Byte
Write_SPI(digits[ByteCnt]);
} while (++ByteCnt < 10);

}
//----------------------------------------------------------------------------
#endif // ___TEST__


bon courrage
