Dear all,I'm using the FatFS generated by STM32CubeMX and I have one question about file size: I'm using f_stat functionand read the file size from fsize field of FILINFO structure; when I open a file I can read the file size from obj.objsize field ...
I've created two USB MSC host applications with CubeMX (1.3.1) for two STM32H743 boards. One of them is a stock Nucleo-H743ZI2 using the OTG_FS interface, the other one is a custom board with STM32H743II using OTG_HS with the internal transceiver.The...
Let me tell you few things.1: I have successfully connected my micro-controller (STM32F103C8T6) as HID device. I made 3 HID devices namely mouse, custom Keyboard and Point of Scale aka POS.and they are working perfectly on Windows and Linux environme...
I want to interface "Honeywell printer" with my USB host machine(STM32F407G-DISC1).So I want to write printer class driver. I am following HAL library.I am using UM1720 (STM32Cube USB host library).But I am also ready for bare metal programming.Seeki...
Hi,# General INFO:I made a custom USB Host Driver for Printer class using STM32F407 - Discovery Board. For This I use HAL Library. I knew that many people don't like this HAL library. I may understand if you guide me through bare-metal programming.Wh...
Hi Actually I,m using stm32f407igh on my board. and I'm using hs usb protocal to send data to PC.but when I measured the usb speed in pc, it is just 10Mbps.I used cubsMX software to set hs usb. In datasheet, it could be maximum 480Mbit/s. why my ...
I would like to know how to use the middleware lwIP but then be able to switch the the interface to a wifi if needed.
After following the instructions in AN5418 and the corresponding Youtube video I am still struggling to get a connection with my NUCLEO-G474RE board to the UCPD monitor. When i am flashing the precompiled binary files, which i downloaded for the X-NU...
Hi, I have a F439ZI where i have set a simple timer (TIM10) to raise the the HAL_TIM_PeriodElapsedCallback every 1 millisecond.The Bus APB2 for timers runs at 168 MHz so i set in the configuration 168 in the prescaler (result is 1Mhz) and the i set 1...
I have array unsigned char data[1024] in RAM , and I need to send them to the display on I2C, this is not problem HAL_I2C_Master_Transmit( data ) works fine. Now I need to send the same data, but so that the sequence starts with a control byte.is I...
