What is your problems?

Yes, please read the details in step 4 and 5.

still 4-bit SDMMC is fastest

The latest display.cpp should look like this, can you check it:...extern "C" void display_init(){ w = gfx->width(); h = gfx->height(); if (w < 480) // assume only 240x240 or 320x240 { if (w > NES_SCREEN_WIDTH) { frame_x = (w - NES_SCREEN_WIDTH) / 2; frame_x_offset = 0; frame_width = NES_SCREEN_WIDTH; frame_height = NES_SCREEN_HEIGHT; frame_line_pixels = frame_width; } else { frame_x = 0; frame_x_offset = (NES_SCREEN_WIDTH - w) / 2; frame_width = w; frame_height = NES_SCREEN_HEIGHT; frame_line_pixels = frame_width; } frame_y = (gfx->height() - NES_SCREEN_HEIGHT) / 2; } else // assume 480x320…

I think 15 fps is already very good enough for 320x240 resolution. There is no meaning step up to 20 or 24 fps except it can reach the normal standard, 30 fps.

not only update Arduino_GFX, also update arduino_nofrendo

ssd1306 is display chip ID, you should keep #include "ssd1306.h" unchanged.

The Arduino_ESP32SPI_DMA class is already obsoleted at Apr 4 commit. Please get latest code and try again.

you may try reduce FPS, say 10, to test is it work.

try set PSRAM: disable

no need to change, it already SD_MMC

Oh yes, 12, 13 and 14 is SD pins. The PSRAM pins should be 16 and 17, I found you already used it. You can always pull-up the LCD RD pin and free up GPIO 32 for LCD DC pin. Then you can use GPIO 27 for LCD D5. And also you can always pull-down the LCD CS pin to free up GPIO 5.

if you are using the ESP32 without PSRAM, uyou can use those pins, e.g. 12, 13 and 14.

you can change PAR8 pins that

FFat is a new filesystem library for replacing SPIFFS, it can run faster than SPIFFS, i.e. much faster than SD card. Currently only FFat can reach 30 fps.

I am not using Bodmer library, can you try Arduino_GFX first?

That is SPIFFS_MJPEG_JPEGDEC_MP3_audio_ESP32I2S8.ino

I heard this error message, the error seems only appear at Windows platform. But since I am using macOS and Linux right now, I cannot check this in short time. I will try this once got an Windows with Arduino IDE.

remove all #include then add:#include "Arduino_GFX_Library.h"

sorry for outdated code, the latest library should use:#include "Arduino_GFX_Library.h"

Try using Arduino IDE

It should be v1.1.2, but require some times for Arduino IDE Library Manager get updated.

If your screen is not IPS, pass false to last parameter, then the color will not inverted.

In latest code, WR should raise after data set.

I am using the pin settings defined at PDQgraphicstest example

but M5core2 is not using 8-bit parallel LCD

I mean can you share your workable code for me to make a quick test

Thanks for your information, I have grouped the WR signal. Would you mind get update and test again?

Sorry for the typo, just fixed, please get update again.

Since both Arduino_GFX and Lovyan GFX compatible to Adafruit_GFX. You may simple replace Arduino_GFX to Lovyan GFX to make a try.

try SDMMC_MJPEG_JPEGDEC_MP3_audio.ino

My sample only show how to sketch NES 256x240 to ST7796 480x320. If you would like to use another display resolution, you are required to pay some effort in display_write_frame() with your own algorithm to sketch NES 256x240 to ILI9341 320x240.

The example code have some tailor-made code for ST7796 resolution(480x320). If you would like to contribute on ILI9341 resolution(320x240), please take a look on display_write_frame() in display.cpp file.

Do you have program experience on other ESP8266 dev board?

Wild guess you should uncomment `// #define T_Camera_PLUS_VERSION` in your code.

change rotate parameters from 3 to 1

Yes, you can move the code from audio file open to audio file close to loop(). And then remove the statistics code after the audio close.

Any hint at the serial output? What size of your display? 2.0 inches or 2.2 inches?If you are first time using this display, you can start from Arduino_GFX example first.

Oh yes, I am sorry about that. I have just fix it, please get latest Arduino_GFX for this issue.

just in case you want to transfer a clipart to whiteboard

The digispark have 2 pins can read analog signal, P2 and P5. However, some clone board keep P5 as reset pin and not yet enable P5 as a I/O pin in efuse. You may test the blink program on P5 to test is it can blink first.

seems power shortage

It is a pull up resistor for SDMMC connection. I have updated step 7 about the connection.

You are using a very old STL other one did. The STL in this instrctables can be much better. Or you can use this latest version: https://www.thingiverse.com/thing:4102658

https://youtu.be/YUDv_-iBEUI

Yes, as it is whiteboard, you can swipe it easily. And then clone anther clipart, or just use same mesh template redraw at another place.

Simply replace Arduino_ILI9225 to Arduino_ST7735

Yes, I just found it. It will be 404 if not yet login thingiverse.

Any white PLA should be ok, I am using 86duino white PLA filament.

you can change to any NES ROM you have and upload to this NES emulator, enjoy!

The STLs are too big to zip together, you can select download only one single size STL file at each time.

It still available:https://www.thingiverse.com/thing:3242080

A similar issue mentioned it may related to power supply: https://github.com/espressif/arduino-esp32/issues/4082When playing with SD, the LCD backlight is noticeable some flicking but not when playing with SPIFFS. Seems SD required a certain power supply.

https://github.com/espressif/arduino-esp32/issues

Since it mostly can solve the problems if retry once, so my new code always write as:if ((!SD_MMC.begin("/sdcard", true)) && (!SD_MMC.begin("/sdcard", true)))

I am not using this module, seems this module is for 5 V Arduino. ESP32 is running at 3.3 V.

can you show more detail to other maker that may encounter this problems?

Ok, you are using SD_* examples, the connection in the instructables is using SDMMC_* examples.

SD_MMC 1-bit not require CS pin

I also have a sd card like that, you may try another card.

Thx, I missed it and fixed it now.

Thx, the connection summary is fixed now. SD card is recommended since it is not easy to extract the game save from SPIFFS ;P

As you can see in above photos, the board pins are named in that way. Any photo of your board?

Ok, I have updated the connection summary indicated the alias name.

try reduce the image resolution

This is a parallel interface display, you will not have enough GPIO remaining for buttons. Or yoy need to use other joypad interface option, e.g. I2C joypad.

Yes, it hard to install on current OS, neither on mine. So I have created a docker image and shared at:https://github.com/moononournation/BanateCADYou may try the docker image by running:```docker run -it -v `pwd`:/lua moononournation/debian-imagemagick-lua-meshlab:1.0.1 sh Examples/cmdLineBatchJob.sh```

look forward for your built post to "I made it".

The voltage depends on the LCD board using, the ST7796 breakout board can use 5 or 3.3 V.

Sorry for the late reply, the key error is 2nd line log:E (7829) SPIFFS: mount failed, -10025I have omitted the step of upload the SPIFFS data, Step 8 is updated for SPIFFS data upload.

in the file display.cpp

Sorry for late reply, simply change line 47 from Arduino_ST7796 to Arduino_ILI9341 should be ok.
