DMA with 16 bit parallel on rp2040/pico

[ripjohnbrown1859]

im trying to run DMA on a 16 bit parallel display with a raspberry pi pico(with the eventual goal being to run data collection on an esp32 s3 and the rp2040 driving the display due to the GPIO requirements. currently the DMA sprites are all corrupted with the text being extremely tilted.
im using a ili9486 480x320 display heres the link

heres the code.

#include <SPI.h>
#include <Wire.h>
#include <TFT_eSPI.h>

TFT_eSPI tft = TFT_eSPI();  // Invoke custom library  
TFT_eSprite spr[3] = {TFT_eSprite(&tft), TFT_eSprite(&tft), TFT_eSprite(&tft)};
uint16_t* sprPtr[3];
uint16_t adcBuffer[100];  //adc data
uint8_t EKGbuffer[320];
uint8_t PLETHbuffer[320];
uint8_t systolic = 0;
uint8_t diastolic = 0;
uint8_t pulse = 0;
uint8_t MAP = 0;
String latestMessage = "No message";
uint32_t benchmark = 0;
uint8_t sensorValue = 0;
uint8_t spO2sensorValue = 0;
uint8_t lastEKGValue = 0;
uint8_t lastSpo2Reading = 0;
void setup() {
  tft.init();
  tft.initDMA();
  tft.setRotation(1);
  tft.fillScreen(TFT_BLACK);
  tft.setTextSize(1);
  tft.setTextColor(TFT_WHITE);
  tft.setCursor(0, 0);
  tft.println("Hello World");
  sprPtr[0] = (uint16_t*)spr[0].createSprite(1, 160);
  sprPtr[1] = (uint16_t*)spr[1].createSprite(1, 160);
  sprPtr[2] = (uint16_t*)spr[2].createSprite(120,320);
  tft.startWrite();
}
void loop() {
  tft.dmaWait();
  spr[2].fillSprite(TFT_BLACK);
  spr[2].setTextColor(TFT_WHITE);
  spr[0].drawFastVLine(0, 0, 120, TFT_BLACK);
  spr[1].drawFastVLine(0, 0, 120, TFT_BLACK);
    MAP = (systolic + (2*diastolic))/3;
  spr[0].drawLine(-1, lastEKGValue, 0, sensorValue, TFT_RED);
  if(lastSpo2Reading > 0){
  spr[1].drawLine(-1, lastSpo2Reading, 0, spO2sensorValue, TFT_BLUE);
  }
  else{
    spr[1].drawPixel( 0, spO2sensorValue, TFT_BLUE);
  }
  spr[2].setTextSize(1);
  spr[2].drawNumber(MAP, 0, 150);
  spr[2].drawNumber((millis() - benchmark), 0, 0);
  spr[2].drawString(latestMessage, 20, 0);
  spr[2].drawString("spO2%",0,90);
  spr[2].drawString("NIBP" , 0, 140);
  spr[2].drawString("HR", 0, 40);
  spr[2].setTextSize(4);
  spr[2].drawNumber(systolic, 2, 160);
  spr[2].drawNumber(diastolic, 2, 200);
  tft.pushImageDMA(1, 160, 1, 160, sprPtr[0]);
  tft.pushImageDMA(1, 0, 1, 160, sprPtr[1]);
  tft.pushImageDMA(360, 0, 120, 320, sprPtr[2]);

  benchmark = millis();
}```
