Hi all!, first of all sorry for my english
I'm developing an Arjan project called "rpidmx512 - dmxMonitor" (Excellent Job Arjan!!!) , and i want to write a file with the current values on DMX signal.
The problem is that i can't write in the SD card... i can read from any file, but imposible update/write.
i'm working with fast fat 12c library, and all the commands (f_mount, f_open, f_stat, f_write, f_sync and f_close) returns 0 value (FR_OK), but nothing change on the SD card. I read here a lot about this in the forum, but i have nothing clear... and i'm also new to the Bare metal programing.
anyone can help me please?
Thanks a lot!
P.S. i'm using RPi 2B & 3B and Sandisk 16GB SD A1 HCI class 10.
