Function Descriptions
EXAMPLE:
The following C program shows the use of SPI functions.
Program Description:
This program runs the following sequence for the SPI for SPI Polling and SPI Interrupt
driven modes:
1. Transmits a single byte passed by the user and receives single byte of data,
2. Transmits and receives the 10 bytes of data,
You can select one pair of the following communication modes, for transmission and reception
respectively:
SPI_POLLING_TX
SPI_POLLING_RX
SPI_ITDRV_WITHOUTBUF_TX
SPI_ITDRV_WITHOUTBUF_RX
/* User can use a time out function to handle the fault in which the control will get stuck in
side a loop.This function should have the Boolean return, i.e it should return TRUE if the
expected wait Time is not elapsed and FALSE if it is elapsed.*/
/*============================================================*/
The following variables are declared in main.h file.
main.h:
#ifndef MAIN
#define MAIN
BOOL User_Timeout_Function(void) ;
void User_Function(void);
void SPI_User_IT_Routine (void);//newly added
#define buf_size 0x0A
#define My_Data (unsigned char)0x55
static unsigned int Timeoutcount;
#endif
