ESP32 and SPIFFS Step By Step

ESP32 and SPIFFS Step By Step.
Working through some example sketches to play video on ESP32 and the ILI9341, I find the wiring for the SD card does not seem to work like it does on the ILI9225. So I push on to use SPIFFS examples. This is when I realize I have not worked with SPIFFS before so let's learn how to work with SPIFFS on ESP32.

man i've been failing so hard for days just to make my own mini tv. i still could not make it work but while watching your videos it makes me smile when you smile :D i guess that makes what all these hard stuff bearable. so thank you. hope someday i can play a video with my ST7735S

[@ShotokuTech]

I think the display will work. It's the ESP32 that has the limitations. There is no separate GPU or sound chip. I like the Raspberry Pi Zero 2 W is a strong candidate. I just thought of that while I was answering your comment.

@@ShotokuTech thank you for this quick response, i was not expecring this. And the solution looks like just what i needed. I will try it. Thank you so much sensei!

[@ShotokuTech]

@@SercanSalkir It will be interesting to see the display connected to the Pi. It's something I have not tried yet.

[@JimmyFungus]

this was a very SPIFFy tutorial!

[@ShotokuTech]

Thanks Jimmy! You nailed it with this comment!

[@thanakolamul6197]

This esp32 series is the best❤️

[@ShotokuTech]

Thanks. I am working on the next one already.

[@JudyFayLondon]

This is a little complicated, very useful, thanks for sharing

[@ShotokuTech]

Thanks Judy. I still learn something new every day!

[@joephilips7265]

no way this was 4 hours ago I've just been fighting through this today lol

[@ShotokuTech]

I tried to get it to you in time! LOL. Thanks.

[@BobHolowenko]

Thank you! You helped me solve my issue.

[@ShotokuTech]

Thank you. Good to hear. Best wishes.

more cool stuff!

Thanks friend.

I finally got this to work, but my .rgb video is all scrambled.

[@ShotokuTech]

The MJPEG video works? Thanks.

Sd card failure may be due to power supply issue. Seems like I saw somewhere that sd card has a spike in current draw that causes failure. I think they added a capacitor somewhere to smooth out the power spike. Maybe this can help you solve your issue. Good luck.

[@ShotokuTech]

Thanks. Yes it seems something may be missing when using the ILI9341 versus the ILI9225 the author is using in their example.

[@tukangngoprek9119]

does it work on arduino 2.3.2?

[@ShotokuTech]

To be honest I have never gone back to try it on newer versions. Mostly because I am always working on the next thing. Best wishes.

[@rdyer8764]

Cool!

[@ShotokuTech]

Thanks. More to come. Taking it one step at a time.

Interesting...🤔

Thanks Cas! 😅

Such a wonderful video

Como yo paso para una variable char el contenido que guarde en el archivo prueba.txt.
Yo hice esto pero no funciona:
File file2=SPIFFS.open("/prueba.txt")
if(!file2)
{
Serial.println(Failed to open file for reading");
return;
Serial.print("contenido ");
While(file2.availble())
{
char rc=file2.read();
}
Serial.print(rc);
file2.close();
No me funciona

[@ShotokuTech]

Parece que estás haciendo algo diferente. La lucha es real, amigo.

@@ShotokuTech Gracias profe pero ya lo logre hice esto:
static byte n=0;
char rc:
char ra[20];
While(file.available())
{
rc=file.read();
ra[n]=rc;
n++;
}
Serial.print("ra ");
Serial.println(ra);
Con esto paso el contenido que tengo en el archivo de SPIIFF a una variable char y luego con esta variable puedo hacer cualquier cosa
