CCS/TMS320F28379D: CCS

It is possible to give me the exact address to see the configuration better
Thanks

Hi,

The examples are available in <C2000Ware>\driverlib\f2837xd\examples\cpu1\spi. This maily includes some internal loopback examples and SPI-SPI external loopback examples.

Thankful
But I want to connect to the LCD with the SPI interface, which definitely needs to send and receive functions.

Hi,

These examples send and receive data using SPI. You can refer to the external loopback example where 2 instances of SPI are connected via wires and data is sent from one to another

Exact address is same as previous address ??

Can this program be used for LCD TFT?

Hi,

I did not understand what you mean by "Exact address is same as previous address ??"

This cannot be used as-is for your case. This basically provides a reference code on how to configure the SPI module, the SPI pins and how to send and receive data using SPI.

In your case, the SPI on the MCU would be the master and LCD would be the slave. The baudrate, the data format, etc might be different for LCD. You need to update them accordingly. You can also update the SPI pins as per your need.

I meant this address

<C2000Ware>\driverlib\f2837xd\examples\cpu1\spi.

Thank you very much for your guidance
Is it possible to ask you again if I had a question ???

Yes. This is relative path from the C2000ware installation directory.

Thank you very much

Example 18-4. 3-Wire Master Mode Transmit
Uint16 data;

Uint16 dummy;
SpiaRegs.SPICTL.bit.TALK = 1; // Enable Transmit path

SpiaRegs.SPITXBUF = data; // Master transmits data

while(SpiaRegs.SPISTS.bit.INT_FLAG !=1) {} // Waits until data rx’d

dummy = SpiaRegs.SPIRXBUF; // Clears junk data from itself

                                                           // bc it rx’d same data tx’d
Example 18-5. 3-Wire Master Mode Receive
Uint16 rdata;

Uint16 dummy;
SpiaRegs.SPICTL.bit.TALK = 0; // Disable Transmit path

SpiaRegs.SPITXBUF = dummy; // Send dummy to start tx

// NOTE: because TALK = 0, data does not tx onto SPISIMOA pin

while(SpiaRegs.SPISTS.bit.INT_FLAG !=1) {} // Wait until data received

rdata = SpiaRegs.SPIRXBUF; // Master reads data

What do these functions mean?
Can I use them as a send and receive function?
