I am new to ST and need support. I want to use USB in my project but I am unable to find a example to use usb as a storing device. Please any one share complete example or any tutorial.
Thank you in advance
I've moved your post to the STM32 MCUs Forum where someone should be able to help you.
Please try to provide additional information (about your device, toolchain that would be use) that might help to get more response.
If you are CUBE user, your can find a working MSC application with different tool chains (EWARM,MDK-ARM,SW4STM32) under the STM32 cube firmware relevent for your device.
(For example, at this path within STM32CubeF4:
The reference Manual and datasheet related to your device will be your support for more details.
Hope this helps you.
I AM using this example STM32Cube_FW_F4_V1.14.0\Projects\STM32F4-Discovery\Applications\FatFs\FatFs_USBDisk\EWARM.It have a problem that it is supporting only 2GB USB. I want to use a 4 or 8 GB USB. is there any guide to it or support to it
I am using this example STM32Cube_FW_F4_V1.14.0\Projects\STM32F4-Discovery\Applications\FatFs\FatFs_USBDisk\EWARM for this stm32f405rg controller. I have connected as
PA12 - to GREEN wire with 22ohm resistor as in discovery
PA11 - to White Wire with 22ohm resistor as in discovery
4.8V - to Red wire
PA10 - to black wire and shorted to Ground also
and when I debug the code it show Appli_state does not change from APPLICATION_IDLE to APPLICATION_START
Help me with it !!!
