Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
I bought B-G474E-DPOW1 and had one typec interface, which cc connect ucpd_dbcc pins. I need another typec interface to send pd message, could I use the ucpd_cc pins for this? And I try to change the demo code "USB-PD_Consumer_1port", set USBPD_PORT_C...
Hi,I got a problem with running USB CDC on STM32G431RB. I configured USB as device and added USB CDC driver. I have changed 'CDC_Control_FS' function in 'usbd_cdc_if.c' file. case CDC_SET_LINE_CODING: LineCoding.bitrate = (uint32_t)(pbuf[0] |...
I have connected the nucleo board to my PC using micro usb cable but when I press degugging button in Keil uVision5 it shows "Internal Command error".How to enable debugging in Nucleo board?
I have a weird problem. I have the Nucleo board with a TLE493 magnetometer connected. When I connect the USB cable (power the system), file manager opens. If I then close the window, upload my SW using Atollic, my magnetometer code works fine, but if...
Hi,I have a working code using STM32F412ZE and I would need to be able to reflash the MCU via USB. One of the things I had come up with is using the DFU. I am also working on a custom board. I had setup the USB pins using the STM32CubeMX. I had also ...
Hello,I writing an application code that will allow the system memory bootloader to be entered via a simple USART receive. I basically followed this post and got it working successfully:https://community.st.com/s/article/STM32H7-bootloader-jump-from-...
I can see that the values 0, 1 and 2 are defined but I've looked through the whole HAL and examples for the F7 and all I can find is uint8_t TypeExtField; /*!< Specifies the TEX field level. ...
Hi, I would like to know if I can use STM32F446 and generate 192k I2s output. consider I need to use USB_OTG_HS.I am trying to setup pins and clock configuration in STMCube, but for the I2S_APB1 it gives me range of 172MHZ to 192. and even with 192 i...
HAL_RCCEx_GetPLL3ClockFreq() computes the frequency of the three outputs of PLL3. When PLL3 is in Fractional N mode it reports wildly inaccurate frequencies which can affect the setup of other peripherals like the SAI.The problem is that the PLL3 cod...
On a STM32F469, when jumping from DFU bootloader to main image, I have seen that the RCC_AHB1ENR register is set to 0x0 and not 0x0010 0000 which it should be after a reset, according to the documentation. This causes the CCM RAM to be disabled.Accor...
