- Sorry for the flickering on the video, in reality LCD content looks perfect
Some pictures are overcompressed, better quality setting should be used in real projects
The library requires about 3KB of RAM
Loading from STM32 internal storage memory and external SD card is implemented
Examples for ST7789 and ST7735
The library on my GitHub:
github.com/cbm...

Another great example of your abilities, thank you for sharing it.
Bruh! Thank you. Been waiting for a while for this video.
Very cool, the days of the green LED are fading.
Watching this makes me wonder why the PC programs use GBs of RAM to run, must be very unoptimized. Good job dude!
Super. Gratuluję. Mój projekt nie chodzi tak szybko, chyba za dużo czujników włożyłem.
Sir, there any way to load jpeg or png files from sd card to screen?
I love STM32F103 😍
Very good, Thank you for sharing your knowledge. Do you have a Tutorial on how to store data in the STM32 internal memory that you are using and how to create eeprom emulation in stm32f103c8t6
i ended with this error 'DATA_SIZE_16BIT' was not declared in this scope' after many previous errors that I encountered.. please give the correct version of the libraries, thanks
COMO CONVIERTES LAS IMAGENES A CODIGO PARA PRODUCIRLAS EN LA PANTALLA ????
Very nice expariment
Hi, could you please show an axample for the function drawImage() from pgm memory ? Thank you
Very Much !!
Good work. Is it a problem to take another display with the STM? Are there libraries for resolution 480x320 and higher?
If slides came from SD-Card and have 300 kB or more are 128 kB enough for decoding?
This library is independent from LCD and GFX library.
every time when I run your example file in Arduino it show "error compiling for board generic stm32f103c series". please can you provide solution on this
I use Arduino IDE 1.6.5. and Roger's stm32duino.
awesome , how did u put Jpeg in internal memory ? i am using an F4 with NAND and SDRAM and LTDC 7" LCD , i did put a picture from NAND to LCD using SDRAM but when picture gets big like 800X480 i cant use HEX anymore,100Kb Jpeg turns into 2MG hex array , i cant find how i can turn picture into array but with Jpeg comperetion.
PS : in your examples seems that u used the HEX file which are quite big(like beach.h which is 45KB) ,are u using BIN too ?
All jpegs in demo slideshow are regular C arrays. There are 12 240x240 images in one sketch. I doubt it is possible to use direct bin files in Arduino IDE.
@@cbm80amiga TNX for your Reply , STM32 has hardware Jpegcodec its even in the CUBEMX , if you want to use that do you have to use it with just jpegs inside SDcart then ?
nice!!! salamat amigo!!
Hello, how to connect SD card (pinout) to STM32 and to the display at the same time?:)
SD Card slot on back of video board.
Здравствуйте. Прошу вас пожалуйста добавьте к вашим исходным файлам все используемые библиотеки, очень трудно все выискивать, и проекты неработают
I compiles at Arduino IDE 1.6.5 and Roger's stm32duino. For ST7789 you need github.com/cbm80amiga/Arduino_ST7789_STM
Can you display a Jpeg file from a SD card by using ESP8266
yes, you can
is it possible to do this project on multiple screens running simultaneously but without onboard sd card?
Yes, it is
@@cbm80amiga how can i get more information about this?
@@ital2474 Look at my other video and the code where I connect 4x ST7735 LCD to STM32. In case of this cheap ST7789 it will not be that easy because CS pin is not available without some soldering.
can i use this on Arduino Uno?
No
Can you show this on ESP32.
Great video, thank you for sharing :)
There are at least 2 JPEG libs for ESP family but I couldn't find any for STM32 so I decided to prepare it myself
Doesn't work for me, I keep getting the "expected '}' at end of input" error.
source?
First! 😍
I was first :)
@@cbm80amiga Yes, because you uploaded it. 😅
Pervonakh?
