drawRect and drawRoundRect does nothing and fillRoundRect bugged calculation.

[TheConceptBoy]

Seems like some of the shape drawing functions are bugged.

This is running on:
Waveshare ESP32-S3 2.06inch AMOLED Touch Watch Development Board, 32-bit LX7 Dual-core Processor, 410×502 Pixels, QSPI Interface, Onboard Dual Digital Microphones Array, ESP32 with Display,No Ba-ttery

I did 4 simple shapes with straight and rounded corners.

#include <Arduino.h>
#include "Arduino_GFX_Library.h"
#include "pin_config.h"
#include <Wire.h>
// #include "HWCDC.h"

// HWCDC USBSerial;

Arduino_DataBus *bus = new Arduino_ESP32QSPI(
  LCD_CS /* CS */, LCD_SCLK /* SCK */, LCD_SDIO0 /* SDIO0 */, LCD_SDIO1 /* SDIO1 */,
  LCD_SDIO2 /* SDIO2 */, LCD_SDIO3 /* SDIO3 */);

Arduino_GFX *gfx = new Arduino_CO5300(bus, LCD_RESET /* RST */,
                                      0 /* rotation */,  LCD_WIDTH, LCD_HEIGHT,
                                      22 /* col_offset1 */,
                                      0 /* row_offset1 */,
                                      0 /* col_offset2 */,
                                      0 /* row_offset2 */);

void setup(void) {
  // USBSerial.begin(115200);
  // // USBSerial.setDebugOutput(true);
  // // while(!USBSerial);
  // USBSerial.println("Arduino_GFX Hello World example");

#ifdef GFX_EXTRA_PRE_INIT
  GFX_EXTRA_PRE_INIT();
#endif

  // Init Display
  if (!gfx->begin()) {
    // USBSerial.println("gfx->begin() failed!");
  }
  gfx->fillScreen(0);

  gfx->setCursor(0, 50);
  gfx->setTextColor(255);
  gfx->setTextSize(5,5, 0);
  gfx->println("Hello World!");


  gfx->drawRect(50, 250, 50, 50, RGB565_RED);
  gfx->fillRect(150, 250, 50, 50, RGB565_RED);
  gfx->drawRoundRect(250, 250, 150, 150, 5, 800);
  gfx->fillRoundRect(350, 250, 50, 50, 15, RGB565_LIMEGREEN);
}

void loop() {
}

This is because CO5300, please use canvas in the middle

Would you mind elaborating a bit please?

I am following the documentation for this unit:

Oop, thank you very much, I got it. Just followed the canvas documentation:
https://github.com/moononournation/Arduino_GFX/wiki/Canvas-Class

I am curious what is the reason for the requirement to have to use canvas? How come the geometry bugs out when drawing directly to the display?
