Good Morning!
I am using LPC1768FBD100 chip, and using USB host for my project. I am using two timers (1ms and 250us). The priority of USB is higher than timers. I am trying read information from USB inside timer (1ms specifically) but it is not working. Is important to know that I am using file system to read/write USB information. Is important to know too that I am opening the file out of the timer and only reading the content of file inside timer. In this process, when function FSUSB_DiskReadSectors is called the process is waiting for USB forever. If I open and read information from USB out of timer, everthing is working fine.
Someone has this problem?
Regards!
Hi Alvaro,
I'm not sure you are going to be able to finish the reading in less than 1 ms, you could do some tests on how much time does it take to finish the reading. Also, I would recommend that you use the f_read function instead of FSUSB_DiskReadSectors.
Hope it helps!
