TC277 SPI CS pin question

[User19581]

We want control the SPI chip select is controlled by the software(disenable hardware module ,use GPIO control it).
How can I achieve this function.

Let's assume you have the iLLD functions IfxPort.c and IfxPort.h:

Find the port and pin index MODULE_Pxx and yy that corresponds to your Chip Select pin:

First set up your pin as an output:
IfxPort_setPinMode(&MODULE_Pxx, yy, IfxPort_OutputMode_pushPull);
IfxPort_setPinPadDriver(&MODULE_Pxx, yy,
IfxPort_PadDriver_cmosAutomotiveSpeed1);

Then set the port high
IfxPort_setPinHigh(&MODULE_Pxx, yy);
or low
IfxPort_setPinLow(&MODULE_Pxx, yy);

Was that what you were looking for?

I remove the CS pin setting from QSPI demo code. But it has error in IDE tool.
How to remove the CS setting?


const IfxQspi_SpiMaster_Output slsOutput = {&IfxQspi0_SLSO6_P20_10_OUT,
IfxPort_OutputMode_openDrain,
IfxPort_PadDriver_cmosAutomotiveSpeed1};

spiMasterChannelConfig.sls.output.pin = slsOutput.pin;
spiMasterChannelConfig.sls.output.mode = slsOutput.mode;
spiMasterChannelConfig.sls.output.driver = slsOutput.driver;
