specific sprites will not display even with psram enabled.

[ripjohnbrown1859]

i am trying to display vital signs next to an ekg and pleth graph, no matter what i do it seems they wont display while the other sprites do display. im using an ili9488 320x480 display with a esp32 wroom node mcu dev board on platform IO with v 2.5.31 of the library . I have psram enabled for all the sprites.
heres the relevant code

uint16_t* sprPtr[7];
TFT_eSprite spr[7] = {TFT_eSprite(&tft), TFT_eSprite(&tft), TFT_eSprite(&tft), TFT_eSprite(&tft), TFT_eSprite(&tft), TFT_eSprite(&tft), TFT_eSprite(&tft)};
void setup() {
  //Set up the display
  Serial.begin(9600);
  tft.init();     // Init ST7735S chip, black tab
  //tft.initDMA();
  tft.setRotation(2);
  tft.startWrite();
  tft.fillScreen(TFT_BLACK);
  tft.setTextSize(1);
  tft.setTextColor(TFT_WHITE);
  tft.setCursor(0, 0);
  sprPtr[0] = (uint16_t*)spr[0].createSprite(240, 120);
  sprPtr[1] = (uint16_t*)spr[1].createSprite(240, 120);
  sprPtr[2] = (uint16_t*)spr[2].createSprite(120,240);
  sprPtr[3] = (uint16_t*)spr[3].createSprite(1,120);
  sprPtr[4] = (uint16_t*)spr[4].createSprite(1,120);
  sprPtr[5] = (uint16_t*)spr[5].createSprite(120,240); 
  sprPtr[6] = (uint16_t*)spr[6].createSprite(240,10);
  spr[6].setTextDatum(TL_DATUM);
  spr[2].setTextDatum(TL_DATUM);
  spr[2].setTextFont(2);
  spr[5].setTextDatum(TL_DATUM);
  spr[2].setTextColor(TFT_WHITE);
  spr[5].setTextColor(TFT_WHITE);
  spr[0].setAttribute(PSRAM_ENABLE, true);

  spr[6].setAttribute(PSRAM_ENABLE, true);
}
void loop(){
  xQueueReceive(xQueue, &payload, 0);
  topSys = payload.systolic;
  topDia = payload.diastolic;
  topSPO2 = payload.lastValidSpO2;
  topBPM = payload.lastValidBPM;
  topMAP = ((topSys + ( topDia * 2))/3);

  
  for(int i = 0; i < 240; i++){
    spr[0].drawPixel(i,119 - payload.EKGbuffer[i], TFT_RED);
    spr[1].drawPixel(i,119 -  payload.PLETHbuffer[i], TFT_BLUE);
  }
  spr[0].pushSprite(0, 0);
  spr[1].pushSprite(0, 120);
  spr[0].fillSprite(TFT_BLACK);
  spr[1].fillSprite(TFT_BLACK);
  spr[2].fillSprite(TFT_BLACK);
  spr[2].setTextSize(1);
  //spr[2].drawNumber(topMAP, 0, 150);
  spr[2].drawNumber((millis() - benchmark), 0, 0);
  benchmark = millis();
  spr[2].drawString("spO2%",0,90);
  spr[2].drawString("NIBP" , 0, 140);

The symptoms suggest PSRAM is not being used and the process runs out of RAM. I suspect only the smaller sprites therefore get created.

Check the board you have is fitted with PSRAM. The PSRAM must also be enabled using the menu option in the IDE.

[ripjohnbrown1859]

well you are apparently correct that my chip has no PSRAM, guess ill order some WROVER boards. even when i size them down to 8 bit sprites they dont display, also 2 of the sprites that are displaying are the same size as the ones not displaying. what pointer var type can i use to get them to be 1bit color since they only need to be 1 color each? i tried setting the ptr var type to bool and it still wont display them.

[Bodmer]

1bpp sprites have an 8 bit pointer i.e. uint8_t

[ripjohnbrown1859]

Ok. Well that still doesnt work. Gonna try taking away sprites until they show up.

[ripjohnbrown1859]

well, i guess theres so little RAM on the WROOM 32 that even when theyre 1 bit sprites, they wont load, i got it to work on my other device by only rendering the most recent reading in a 1 pixel wide sprite but thats not really practical here with the may im sending data.
