Did anyone managed to read CANBUS without canbus peripheral? (softcanbus)
Is there any way for chips without the Canbus peripheral to read canbus?No external chips allowedMaybe uart or bitbanging gpios?

How to setup PMA buffers for isochronous USB transactions
Hello, I've been trying to port the X-CUBE-USB-AUDIO library onto a STM32G0B1RE nucleo board. Right now, I'm struggling with the configuration of PMA buffers. My configuration right now : HAL_PCDEx_PMAConfig((PCD_HandleTypeDef*)pdev->pData, 0x00,...
stm32h750vbt6 adc datasheet data testing .
hello ı use stm32h750vb , I'm trying to get the adc values in the datasheet.Is the adc operated in continuous mode or in single mode when sampling rates are found.If I run it in continuous mode, I can access the values in the datasheet. But this ...
Resolved! read access to the input GPIO pin in alternate function ?
Hello,I need a clarification whether it is possible to read any pin status in alternate function just as it were a normal GPIO input pin. Is it so?For ex. I configured the alternate function for a pin as a Timer Channel Input Capture pin, yet I can s...
Resolved! Can we have dedicated DMA channels for each USART of STM32F030CC
Hello Team,I'm newbie to STM32F030CC, in this 6 USART channels are present, I want to use all the 6 USART's via DMA channels, but the available DMA channels are only 5 and also for Tx and Rx dedicated DMA channels are required, in that case I assume ...
I'm trying to set up UART9, And use it by DMA1. But I think that UART9 CLK are not enableת because of I didn't get any DMA1 Interrupt.
/* UART9 init function */void MX_UART9_Init(void){ /* USER CODE BEGIN UART9_Init 0 */ /* USER CODE END UART9_Init 0 */ LL_USART_InitTypeDef UART_InitStruct = {0}; LL_GPIO_InitTypeDef GPIO_InitStruct = {0}; LL_RCC_SetUSARTClockSource(LL_RCC_USART16_CL...

Resolved! Memory map and register boundary addresses (for STM32H7A3)
Hello,I am interested in seeing the memory map of the H7A3. I have been able to find some information from the HAL drivers, but there is a lot missing. That table does not exist for the H7A3 in the reference manual, which is where the datasheet says ...
ADC Conversion time for stm32h750vbt6 ?
Hello,I am trying to measure the adc cycle time with the help of an oscilloscope, what is the most precise and correct solution?, I would appreciate if you could help me what method should I follow to measure it.
