I am using a simple polled ETH RX process. The 10ms poll period limits data rate to 250kbytes/sec which is more than enough for the application, but it does introduce a latency of up to 10ms.Please don't tell me to use interrupt driven RX unless you ...
I'm using STM32G473 with the STM32_USB_Device_Library files. I set up a custom HID device with 1 IN EP. It is enumerating correctly and can successfully communicate bulk transfers with the host (proprietary software proven to work with other STM32 MC...
Some time ago I designed a simple CAN to USB device. It accepts CAN network packets, then converts them to a binary packet that is sent to the virtual COM port. It works very well. However, the Virtual COM Port is limited to about 1MB/s even thou...
There appears to be a minor bug in HAL_TIM_IRQHandler(), in stm32f7xx_hal_tim.chttps://github.com/STMicroelectronics/STM32CubeF7/blob/master/Drivers/STM32F7xx_HAL_Driver/Src/stm32f7xx_hal_tim.cAPPARENT-BUG SUMMARY:There's a line-of-code that works, b...
If i am generating PWM pulse by uing TIM1 (PA8) my ethernnet not worming? for ethernet config i m using CMSIS lib provided by STPwm configuration is s follows RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE); RCC_APB2PeriphClockCmd(RCC_APB2Periph...

The function "__weak void HAL_SYSTICK_Callback()" is implemented in "stm32f4xx_hal_cortex.c"I overwrite it in the "main.c", I compiled project, but my project still does not work.void HAL_SYSTICK_Callback(void) { HAL_IncTick(); }Why am I wrong ?Wher...
Hello!I'm working on a STM32H743I use a USB DEVICE driver (pins PB14 and PB15) : only AF12 is possibleI also use a SD card driver (PC8 ... PC12) : only AF12 is possible(Alternate function mapping is described in the datasheet https://www.mouser.fr/d...
