Good afternoon.
I am programming a microcontroller STM32F103 and appeared to me some conflicts.
For the graphical interface of the LCD I use the library uc/GUI, but when I trying to save the data on a memory card I can only create the txt file and I can't write on it. To create the file I'm using the function f_open() of the FatFs library and to write in the card function f_write( ), however the file is always empty.
The memory card is a micro SD of 64 MB.
I test the code to write in the card separately of the code of the interface and it worked well, but when join the two codes that I have, I cannot write in the file.
Does anyone know what may be happening?
Thank you.
