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...
