Posted on October 24, 2017 at 11:30I use STM32F103, DMA1->CH6USART2 RX and TIM3 TIM3_CH1 both can use this channel.If only USART2 RX or TIM3 TIM3_CH1 to use this channel,it is ok!but how to multi use for two request?thank you very much.
Hi everyone: As a title,I use dma Usart Rx for DMA1 Channel 3,but at the same time, I also use Spi Tx for DMA.So , I must remap Usart Rx from DMA1 Channel 3 to DMA1 Channel 5.I try to use this function SYSCFG_DMAChannelRemapConfig(SYSCFG_CFGR1_USAR...
I recently obtained an STM32F779I-EVAL board and was surprised to find that a copy of the demonstration software didn't come with the kit. Yes, there is a version loaded onto the board, but I would like to look at the software for guidance and anyway...
I have code that runs on the NUCLEO-F767ZI kit and have recently obtained the STM32F7779I-EVAL kit. My program is very simple, it does not do any IO (yet), so I (perhaps naively) thought that just changing the processor type in my IAR Embedded Workbe...
I have trying to implement the in application programming where as to hold the large binary of the application which i need to program into internal flash i use Rx_Buffer mapped in external SDRAM,so when i call HAL_SDRAM_Init() function the flash er...
The JPEG decoder output DMA aborts after a few iterations. In the function HAL_DMA_IRQHandler, the hdma->state shows that it is in abort state. What can cause the JPEG output DMA to abort?I am using the HAL JPEG decoder on a stm32F779, the JPEG decod...
I am working with SD card in SDIO mode. The current version of cube mx i.e, 4.27 is not working. Some people in the community posted that after version 4.21 SD card issue is persistent. so i would like to download 4.22Youtube link I have followed: ht...
Following a guide to view run-time statistics. The guide says to set up a hardware timer, "The timer used for collecting these statistics must use a higher resolution time base than the tick interrupt that is driving the scheduler, otherwise the stat...
Hi,I am having a problem with using internal EEPROM memory for saving data. I can read data only from BASE adress of EEPROM. I can not write to EEPROM or read form any other place in EEPROM.MY simple code:#define FLASH_EEPROM_BASE ((uint32_t)(FLA...
