MCU: STM32F105RCTxFirmware Version: STM32Cube FW_F1 V1.8.0I have DMA setup to read 8 channels of the ADC into a fixed buffer and I'm having an issue where after an extended period of time (usually hours) the ADC channels are read into the wrong buffe...
I am trying to get the USART3 to work with DMA, and so far have been unable to. After the initial cubeIDE project setup, I verified that standard (non DMA) RX and TX were working fine.Moving to DMA, I was getting Direct Mode Error interrupts, and a l...
Hi,I am using STM32F746G_DISCO board to create different pages for the LCD. I see only one page with 4 tabs project already takes 300KByte flash memory code space. The STM32F746 only has 1MByte flash. So I like to store the LCD graph code related mo...
Hello everybody!I can't use USART2 in STM32G030K8 to transfer data.The TC flag of the ISR register is not set after writing data to the TDR register for an infinite time, if I use it to control the transfer of a byte, the program hangs without transf...
We have connected 7 channels in ADC2 to a STM32F769II processor. The DMA to ADC is enabled and the rank for conversion too is configured. But on testing, the ADC values are being shown in buffer location very different from its rank.This happened in ...
Hello!i am working with the STM32H745 dual core nucleo board.i have noticed that the app that i built runs perfectly when i debug it using IAR, on the other hand, it does not when i just connect the nucleo board to power and try to communicate with i...
please let us know the availability of STM32L496RET6 controller
i use two uart.(usart1 & usart2).when i receive data(usart1), first, the program will into "void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart)".but when i i receive data(usart2), second, the program will not into"void HAL_UART_RxCpltCallback(UA...
