TFT eSPI を使ってみた。

コード

#include "FS.h"
#include "SD.h"
#include "SPI.h"
#include "TFT_eSPI.h"

TFT_eSPI tft = TFT_eSPI();       // Invoke custom library
SPIClass sd_HSPI(HSPI);
#define HSPI_SCK  14
#define HSPI_MISO 35
#define HSPI_MOSI 13
#define HSPI_SS   15

static uint8_t data1[120 * 320];
static uint8_t data2[120 * 320];

void testOriginalData() {
  tft.pushImage(0,   0, 320, 120, data1);
  tft.pushImage(0, 120, 320, 120, data2);
}

bool readFile(fs::FS &fs, const char * path){
    File file = fs.open(path);
    if(!file){
        Serial.println("Failed to open file for reading");
        return false;
    }

    file.read(data1, 120 * 320);
    file.read(data2, 120 * 320);
    file.close();
    return true;
}

void setup()
{
// Setup the LCD
  tft.init();
  tft.setRotation(1);

  sd_HSPI.begin(HSPI_SCK, HSPI_MISO, HSPI_MOSI, HSPI_SS);

  Serial.begin(115200);
  delay(100);

  if(!SD.begin(HSPI_SS, sd_HSPI, 12000000L)){
      Serial.println("Card Mount Failed");
      return;
  }
}

void loop()
{
  //randomSeed(1234); // This ensure test is repeatable with exact same draws each loop
  char buf[255];
  int x, x2;
  int y, y2;
  int r;
  
// Clear the screen and draw the frame
  tft.fillScreen(TFT_BLACK);
  unsigned long old_time;
  for(int i = 1; i <= 100; i++) {
    sprintf(buf, "/output/%04d.dat", i);
    old_time = millis();
    Serial.println(buf);
    if(readFile(SD, buf)) {
      // put your main code here, to run repeatedly:
      testOriginalData();
    }
    Serial.print((float)1/(millis()-old_time)*1000);
    Serial.println(" fps");
  }
}
