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'm not sure how I did it, but my Blue Pill STM32F103C8T6 doesn't respond to st-info --probe any more. This has happened twice in a row with identical devices. It seems that if I Ctrl-D out of GDB (an old bad habit) the device seems to brick itself a...
Hi all,after working with Arduinos for some time now, I am currently trying to get stuff to work using a blue pill (stm32f1). I've managed to get some code working that turnes on the builit-in LED when a button is pressed using the Arduino IDE.With ...
Hi there, I am currently working on power optimization for my application. My code runs at 80MHz HSI, so in order to implement sleep mode I am dynamically changing the clock to 2MHz. After system changes to 2MHz, I am disabling the systick using the ...
So, a month or two ago, I had an issue where my USB 2.0 wouldn't connect and kept giving an error that the device descriptor wasn't detected. I found out at the time, that it wasn't properly generated, added it and all was fixed. Well, more problems ...
Good morning everyone,I'm currently trying to implement a SPI slave in full duplex mode on a STM32F469IDISCOVERY in order to interface with an external Master that is working at 10Mbit/s (the master cannot be modified). What I need to do is a full du...
We have a problem converting our running USB VCP application (RTOS) to a working RNDIS version.We replaced the regular variants of usbd_cdc.* and usbd_cdc_if.* by their RNDIS variants.The USB OTG HS clock is enabled.We adapted the initialization: ...
Hello,I stumbled upon a cubemx generation issue for sdmmc2 for the stm32u5g9zjt6q (I didn't have this issue with some other stm32u5xx).For a basic cubemx configuration of sdmmc2, the HAL_SD_MspInit is wrongly generated. It is a bit annoying as I have...
phy芯片设置百兆全双工自协商连接千兆交换机时网络ping不通，连接百兆交换机正常 P1连接千兆交换机phy寄存器 P2连接百兆交换机寄存器 P3主控关键寄存器 Translation: When the Ethernet PHY chip is set to 100M full-duplex auto-negotiation and connected to a gigabit switch, the network ping fails, but it works normally when...
When using the register callbacks feature ( USE_HAL_UART_REGISTER_CALLBACKS = 1) , the BSP does not register the default callback, causing the serial port not to work. Fix: diff --git a/Drivers/BSP/STM32G4xx_Nucleo/stm32g4xx_nucleo.c b/Drivers/BSP/S...
On STM32G0 is it faster to disable and enable interrupts using the functions __STATIC_FORCEINLINE void __enable_irq(void) { __ASM volatile ("cpsie i" : : : "memory"); } __STATIC_FORCEINLINE void __disable_irq(void) { __ASM volatile ("cpsid i" : :...
