why? TouchGFX compiler throws this error Core/Src/main.c:25:10: fatal error: fatfs.h: No such file or directory #include "fatfs.h"

[Miguel Moran]

I am developing a small project to which I decided to add a USB-HOST in MSC (Mass Storage Class) mode, with the intention of adding a USB pen drive, obviously I require the use of FATFS (USB-DISK mode) drivers. However, the Touch v4.14 compiler gave me the error:

Core / Src / main.c: 25: 10: fatal error: fatfs.h: No such file or directory #include "fatfs.h"

I did not understand why, if KEIL v5.31 did not throw any error.

I tried several movements but I continued without favorable results

until you remember the famous "makefile" of the touchgfx, explore it and try again adding the path where the file was and "done" was all

[Miguel Moran]

Just add the following lines marked in black, which correspond to the paths where the * .h are that the TouchGFX did not compile and the Keil did.

I hope to be helpful!

Hi @Miguel Moran​ 

This is because the simulator knows nothing about FATFS or any other hardware specific code. You need to exclude that from your code using the directive

#ifndef SIMULATOR and basically write dummy code to be used when in simulation.
