Hi Guys,
I am implementinng multiple slave Functionality on TC222.
I dont know how to initialize master channel when we have more then 1 Slave.
Can any one guide me.
Here is my source code for youre reference to initialize master channel for one slave.
/* QSPI1 Master channel initialization
* This function initializes the QSPI1 Master channel.
*/
void initQSPI1MasterChannel(void)
{
IfxQspi_SpiMaster_ChannelConfig spiMasterChannelConfig; /* Define a Master Channel configuration */
/* Initialize the configuration with default values */
IfxQspi_SpiMaster_initChannelConfig(&spiMasterChannelConfig, &g_qspi1.spiMaster);
spiMasterChannelConfig.base.baudrate = QSPI1_BAUDRATE; /* Set SCLK frequency */
spiMasterChannelConfig.base.mode.clockPolarity = SpiIf_ClockPolarity_idleLow;
spiMasterChannelConfig.base.mode.shiftClock = SpiIf_ShiftClock_shiftTransmitDataOnLeadingEdge;
spiMasterChannelConfig.base.mode.csInactiveDelay = SpiIf_SlsoTiming_1;
spiMasterChannelConfig.base.mode.csLeadDelay = SpiIf_SlsoTiming_1;
spiMasterChannelConfig.base.mode.csTrailDelay = SpiIf_SlsoTiming_1;
/* Select the port pin for the Chip Select signal */
const IfxQspi_SpiMaster_Output qspiSlaveSelect = { /* QSPI3 Master selects the QSPI3 Slave */
&IfxQspi1_SLSO3_P11_10_OUT, IfxPort_OutputMode_pushPull, /* Slave Select port pin (CS) */
IfxPort_PadDriver_cmosAutomotiveSpeed1 /* Pad driver mode */
};
spiMasterChannelConfig.sls.output = qspiSlaveSelect;
//spiMasterChannelConfig.sls.output.pin = IfxQspi1_SLSO3_P11_10_OUT | IfxQspi1_SLSO4_P11_11_OUT |IfxQspi1_SLSO5_P11_2_OUT;
//spiMasterChannelConfig.sls.output.mode = IfxPort_OutputMode_pushPull;
//spiMasterChannelConfig.sls.output.driver = IfxPort_PadDriver_cmosAutomotiveSpeed1;
//spiMasterChannelConfig.mode.autoCS = (chHandle->activateSlso == NULL_PTR) && (chHandle->deactivateSlso == NULL_PTR);
/* Initialize the QSPI Master channel */
IfxQspi_SpiMaster_initChannel(&g_qspi1.spiMasterChannel, &spiMasterChannelConfig);
}
