Hello Everyone,I am currently using STM32F7XXX eval board.I wanted to interface a external battery, which can power up the board.Can anyone suggest on How to proceed on this? As I am new learner.Thanks in Advance.
I am using stm32f779I eval kit. I am using example UART_HyperTerminal_DMA by en.stm32cubef7.I am trying to implement UART in DMA mode to transmit a simple string.So I have used CubeMX to generate the code and I have configured UART1 TX DMA in normal...
Hi All,I am using STM32F779I- eval kit.I am using DMA Burst mode. I have created two buffers(buffer1 and buffer2) with different sequence.Lets say Buffer1 with sequence 1 is running using HAL_TIM_DMABurst_WriteStart () HAL API. In between of sequence...
Hi,I am working on stm32f779 eval kit.I am using quad spi.Following sequence works fine:Sequence 1:Erase any sector-> write value to particular sector -> read values from correct sector.Not working sequence ->Sequence 2:Erase a sector -> read values ...
polling UART (HAL_UART_Transmit) and HAL_UART_Transmit_IT both are working properly.Even Uart Rx in dma mode is also working properly. Having issues with Uart TX DMA only.
Hi,I have added code as suggested by you:Print(){HAL_UART_Transmit_DMA(&UartHandle, (uint8_t *)ch, len); while (HAL_UART_GetState(&UartHandle) != HAL_UART_STATE_READY) { }} But after HAL_UART_Transmit_DMA() execution pointer goes to void DMA2_Stre...

My issue is same ashttps://community.st.com/s/question/0D50X00009XkgtY/dma-uart-with-hal-remain-busy-bugbut solution provided in this link is not working for me.Already HAL_UART_IRQHandler() enabled.
