The application reads picture-files in standard Windows BMP-format from a SD-Card and shows them on a 2.8" color-LCD-module (320*240 px).The application also uses the FAT File System Module by Chan, on which M. Thomas ported to work on STM32 SPI interface. Additional information about this project can be found on the link above.
Some of the minor modifications I made were:
- I've modified the LCD driver so that it will work on my unit. My unit got the ILI9320 LCD controller.
- I didn't utilize the USART interface (but this can be easily enabled in the code). In stead of sending the "information" through this interface , some of them are being displayed on the LCD itself (e.g. bitmap filenames).
- I've enabled the two push-buttons on the board. The first one toggles between "Play" and "Pause"; and the other one is to "Restart" the "slide-show" from the beginning.

Hello! Great Work!
ReplyDeleteIs it possible for you to save the project as uVision3 and post it here?
Thank's in advance!
Hello!
ReplyDeleteCongratulations! Excellent work!
I've tested your code on my miniStm32... works like a charm :)..
I'm still trying to understand the code, but the fatfs is still breaking my nerves :s
I'm using your code as a first approach to SD card interfacing. I need to be able to write raw ADC data to a .txt file. If you have any code sample doing something like that, would be nice if you could send it to me to: ricardo.mgat@@@gmaildotcom
ps:. hope you catch my email
keep up with the good work!
@ 'Anonymous',
ReplyDeletehere's the exported project to uVision3 format:

@Ricardo,
I don't have a complete sample for that yet, but you can start with Petit FAT-FS (also by ChaN),
since it is simpler and easier to understand than the full-feature FAT file system.
@yus
ReplyDeletethank you for the help on this!
I've been able to write to the sd card now, I've used your code and ChaN's: f_open(); f_printf(); f_close();
Now just need to learn how to use the ADC feature, and most important, find two free analog inputs on the miniSTM32.
Once again, thank you for your help and keep up with the good job..
Best regards,
Ricardo
link to uVision3 version is not working.
ReplyDeleteI have the stm3210c-eval board, how can I change this code to in it, that I can see a slideshow too? Have you an program or can you tell me how it works?
ReplyDeleteBest regards,
Carlo
great work !
ReplyDeletethanks for sharing :-)
for those who build custom boards :
in the soft RAR package the comments in LCD file says
hardware connections PE0~15 <----> DB0~15
but in the soft code it's not PortE , but PortB and PortC
(like in Martin Thomas source)
maybe it's only comment mismatch , i guess the code itself works ! :-)
Hi ,
ReplyDeleteThe link for uVision3 is not working...
could you please post new link??
Thanks

ReplyDeleteWork thank you
ReplyDeleteAs the design of this one is truly looking just elegant. And the LCD screen of this one is really looking rocking and impressive. The classy look and the incredible feature of this digital picture frame really makes me crazy about it. Thanks for sharing.
ReplyDeleteThanks for a great project.
ReplyDeleteI purchased the exact board MiniSTM32 V2.0 and flashed it successfully with a Ulink 2. I get the first screen displayed flashing but there is no slideshow.LED D3 flashes. If I press switch S1 the LED D2 comes ON while D3 continues to flash. If I press switch S2 then I get "Slideshow restarted by user" displayed on the LCD. But the pictures never get displayed. I have tried with a 1 GB microSD as well as a 32Mb MMC card.
Any ideas on what I am doing wrong ?
Sir I am using your PhotoFrame Project with SPI interface. All Fat routines and TFT is working fine and the bmp images i picked up from internet. But problem is that the code doesn't displaying images and it shows Text and BMp detected message but no display from MMc card. as my MMC card is also working fine, Is there any problem in BMP images in the MMC card??
