Here below image of the MCU on my two nucleo boards. I tried to program the MCUs using SMT32CubeProgrammer and USB-TTL converter connected to USART1 via pin PA9 and PA10, BOOT pin tied to 3V3. I press the reset button, then try to connect F070 MCU bu...
Section 2.1.2 of AN4938 states: If a USB interface is used (USB OTG_HS/OTG_FS), the associated GPIOspowered by VDD33USB operate between VDD33USB_MIN and VDD33USB_MAX(seeFigure 2).VDD33USB supplies both USB OTG_HS and USB OTG_FS transceivers. If onlyo...
I am working on a tool for embedded Linux that can update MCU firmware on a NUCLEO-L4A6ZG. I power up the MCU in DFU mode and connect using LibUsb in user mode.I get an error when a try to read from address: 0x08000000First I successfull write the ad...
hi guys, i'm stm freshman, I am trying to read the adc value by using the adc example of stm32f4, I added bold code to get uhADCxConvertedValue value, but uhADCxConvertedValue value always get 0 Whether I connect adc pin to grounded or vcc.the led4 ...
I'm working on a project in which I would use another MCU to burn program onto STM32 MCU over USB, but I can't find USB bus timings anywhere. That other MCU will also have other functions. When powered on it should check sd-card for the binary file a...
I'm trying to import our old code from 7.3 to 8.32.1 and have a problem with classb tests. To see that the problem is not in our code, I have tested the project included in Class B STM32 Self-test library (Projects\STM32L476G_EVAL\EWARM) and it behav...
I am laying a board for the first time with a an STM32H745ZIT and I'm wondering how I should connect the 2 unused USB power supply pins? I can't find anything in the data sheets, but I'm guessing I can leave them unconnected or maybe ground the input...
I am new to Ethernet. What I am trying to do is to use it to send a packet from one board to another. What I did:Changed the default RAM to D1RAM to start from 0x24000000 to store the DMA descriptorsConfigured the MPU for the DMA Descriptors - I will...
I am trying to get the STM32F722 to interface with the USB3300 external HS PHY (ULPI). I have generated code from the cube. I been doing digging.. the "USBD_CDC_Init" function never get called and pClassData is always NULL. I have tried changing the...
I'm writing a UVC driver for a STM32F205 and I have the probe/commit working as I am getting the max/min settings from the camera and the cameras streaming light comes on when I set the video streaming interface to the desired one. The only problem I...
