Hai All,
We can configure a GPIO pin either as a Push-Pull or Open-drain configuration. Can anybody explain briefly, what are the applications of Open Drain configuration?
Hai All,I am using USB OTG using ULPI protocol in my STM32F series controller.I entered a print statement inside the USB interrupt handler to monitor the interrupt. Then I found that whenever I connect USB drive the interrupt is hitting continuously ...
Hai All,
I am facing an issue on USB File system accessing. Here I am using ULPI protocol for accessing the USB Drive via USB3300 IC.Here I am using an Interrupt method for detecting the USB drive. When we connect, interrupt is happening and File dir...
Hai All,I am working on STM32F205VET and I have enabled USB Mass storage, SD Card and FATFS. I need to use SD card and USB mass Storage at a time, that means need to access the files.But I found that based on the FATFS_LinkDriver preference makes tha...
@Peter BENSCH Thanks for your reply.My doubt is ,as long as I keep the USB drive in connected state,whether the USB interrupt will hit continuously? We know that , in GPIO interrupt, while the key is pressing interrupt will generate but if I keep the...
@FBL No, I didn't face any issue on SD card, it is happened only in ULPI. After disabling the pin SOF from the code it is working good.Could you please tell me the root cause behind this, if you know?
Hai @FBL Yes, I fixed this sector size as 512 and 1024.I have a doubt, I have Enabled SOF pin in this protocol.Whether it will create any problem.Do you have any idea?
I am using STM32F205VET6 controller. Here only I have tested the firmware.Here I will give you the pat of the code where the issue is exactly happens.The function is FRESULT find_volume. A part of the code is given below. #if _MAX_SS != _MIN_SS /* G...
