Hello,I am looking for an example of STM32FDiscovery. So I found STM32FCube_FW_F4_V1.24.0.STM32Cube_FW_F4_V1.24.0\Projects\STM32F4-Discovery\Applications\FatFs This example worked.Create USB MSC + FATFS project with CubeMx. I wrote the code using t...

Hello.I want to operate the USB HOST MSC as FATFS with STM32 F4.My code periodically records data to usb.It works normally for quite a long time.But if it works for a day, the mcu keeps stopping.The problem seems to be periodic f_write. Because it do...

Hello,A project created in truestudio generates a HardFault_Handler.There are 2 PCBs I made. PCB A and PCB B are the same circuit and components. I have confirmed that the operation is correct while writing the code in PCB A.However, there was a prob...

Hi.If power is applied while USB is plugged in, it is possible to read and write data with USB MSC and Fatfs.I am looking for a way for USB to be detected when I plug in USB while STM32 is running.Even if I look for a way, I found only STM32 device....

Hi.I changed the debugging tool from IAR to trueSTUDIO for STM32.There is code that IAR created and completed the operation. However, the same code, but does not work in trueSTUDIO.An example of the code is shown below.int a = 0;void HAL_TIM_Pe...

The reason I enable/disable IRQ is the Critical Section. The solution I found was to have the application of FATFS handled a similar problem by conducting a Critical Section. The person who created this method uses sd-card.However, there was a proble...

I understand that USBH_UserProcess will call back the usb state and change the Appli_state.In the STM32Cube_FW_F4_V1.24.0 \Projects \STM32F4-Discovery\Applications\FatFs\FatFs_USBDisk example I have found that USBH_UserProcess is called every time a ...

I looked up what you said. You have seen that the PCDET bit in OTG_FS_HPRT tells you the control and status of the host port. However, I need help with usage. I do not know how to use the OTG_FS_HPRT register.When I try to use a register in main.c I...

As in the example, it's in the main function.In Cubemx generated code "fatfs.c"char USBHPath [4]; I found what was declared as.The file added "ff_gen_drv.h" to usb_host.c.What files should I include?

Debugging at the start and end breakpoints of SystemClock_Config (). It seems to work correctly by entering a function.
