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...
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" : :...
I took the following code example from STM32h747 discovery git. Even though I have specified the number of channels as "2". The data at location 1, soon is zero which means R right channel data is always zero. Please let me know if something is wro...
Hello,I am listing files on the SD card using fileX. My issue that some of the files contain Czech Characters (eg. č,ž,ě,š and few more). It seems that files with czech characters are read with shortened file names. (FX_MAX_LONG_NAME_LEN is set to 25...
