Hello,I would like to confirm how VBUS behaves in STM32 USB OTG depending on the Host/Device mode.Specifically, I would like to ask the following:When STM32 is configured as Host mode, should the STM32 source 5 V onto VBUS?When STM32 is configured as...
Hello,I the Reference Manual (RM0410 Rev 5) for STM32F769I-DISCO, DMA_P1 is not shown connected to AHB Bus Matrix. It is intentional or error in the diagram ?Thanks,Debasish Das
Hey I am having trouble tryng to connect my stm32g473 to a canbus. I am using a l9616 as a transceiver and the bus is functions as I have connected to it with an stm32f722re with the same l9616.The clock is 64Mhz,Ive used the canbit time calculation ...
Hello Community,I am migrating a prototype CMake application to TrustZone for a test board targeting the STM32U575VGT6 MCU. Launching a debug session for my project generates the following errors. `I've attached verbose console error output in the ...
In the document UM3234 we see the following description of clock configurationOn my Nucleo board, I haven't blown any fuses and measured a clock frequency of 32 MHz. Since the XSPI is configured to have a prescaler of 2 by BOOTROM (also mentioned in ...
Hi Folks, I'm working on pattern generation on GPIO pins and I've done it successfully using bare-metal programming approach. I used TIM1 to trigger DMA2 to take data from a buffer and send it GPIOA->BSRR. But when I try to change the timer from TIM...
Hello,Using a NUCLEO H7S3L8, I'm trying to run a test where, using circular DMA with a linked list, I'm trying to send a buffer in memory over to the SAI for audio playback, using an external DAC. This configuration is based on either other tutorials...
Hi guy I want to use Nucleo h755zi-q to sent modbus TCP/IP but I have a little time and I'm a beginner. I watched some GitHub but I don't understand. Some one can help me pls
I am currently performing the bring-up of a custom PCBA using the STM32H755ZIT3.My design is intended to use the Internal LDO only, bypassing the SMPS to reduce component count (i.e. one less inductor in my layout).Here's few details about the MCU po...
I am using the STM32G474 in STM32CubeIDE with the built-in CubeMx environment. MX_DAC1_Init() to setup the DAC1_Ch1. Internal VREF+ is 2.9V. When it is buffered DAC, I get output very close to 2.9V at max(4095). However if i switch to unbuffered mode...
