SIMPLELINK-CC13XX-CC26XX-SDK: Newhaven display oled

Yes ...new haven display -4x20 that same oled module 

I have planned to use pcf8574 an I/O expander to connect with display in I2C mode.

can you help me with the hardware connections and  to be controlled through I2c with cc2652psip

In SPI TI driver , there exists SPICC26XXDMA.h File ,for cc2652 devices . Shall we use it ?

#include <SPI.h>

// Pin Definitions
#define RS_PIN      4   // Data/Command select
#define SCLK_PIN    13  // SPI Clock
#define SID_PIN     12  // SPI Data (MOSI)

void sendCommand(uint8_t command) {
    digitalWrite(RS_PIN, LOW);  // RS = 0 for command
    SPI.transfer(command);
}

void sendData(uint8_t data) {
    digitalWrite(RS_PIN, HIGH);  // RS = 1 for data
    SPI.transfer(data);
}

void initDisplay() {
    // Initialize SPI
    SPI.begin();
    pinMode(RS_PIN, OUTPUT);

    // Display initialization sequence
    sendCommand(0x28);  // Function set: 4-bit mode, 2 lines, 5x8 dots
    sendCommand(0x08);  // Display off
    sendCommand(0x01);  // Clear display
    sendCommand(0x06);  // Entry mode set: Increment cursor
    sendCommand(0x0C);  // Display on, cursor off, blink off
}

void displayText(const char* text) {
    while (*text) {
        sendData(*text++);
    }
}

void setup() {
    initDisplay();
    displayText("Hello, World!");
}

void loop() {
    // You can add code to update the display here
}

will this code run and be flashed through code composer ?, please indicate steps to connect with command codes of display.

Thank you Ryan, I am trying to write my own driver for the display using the SPI Ti driver.
