I am converting code from a Atmel AVR project into S12XE. I am getting warnings that relate to return values not being used. What is the work around for this.
This is typical of the items that are causing the warnings SpiWriteRead(AT45DB041B_CMD_STATUS_REGISTER_READ);
Below is the offending code.
Ray.
//----------------------------- SPI Write ----------------------------------
void SpiWrite(uint8_t data)
{
while (!SPI0SR_SPTEF); /* Wait for empty data register */
SPI0DRL = data; // initiate write
}
//-------------------------------- SPI Read -------------------------------------
uint8_t SpiRead(void) {
while ((SPI0SR & SPI0SR_SPIF_MASK)); /* Wait for data in the receive buffer */
return(SPI0DRL); /* Return received data */
}
//---------------------------- SPI Write Read ------------------------------
uint8_t SpiWriteRead(uint8_t data)
{
uint8_t rxdat;
SpiWrite(data);
rxdat = SpiRead();
return(data);
}
//---------------------------------------------- AT45DB Get Status --------------------------------------------------
uint8_t at45db041b_get_status(void)
{
uint8_t data;
// Select serial Flash
DF_CS_active;
// Send command
SpiWriteRead(AT45DB041B_CMD_STATUS_REGISTER_READ);
// Read status
data = SpiWriteRead(0x00);
// Deselect serial Flash
DF_CS_inactive;
return data;
}
