Posted on September 28, 2017 at 08:43Hello!I am trying to use USART2 + DMA for Rx/Tx. Tx is working OK already.For Rx, I would like to use DMA circular mode.I use followings. STM32L476 nucleo STM32CubeMX, STM32CubeL4 1.9.0.After do workaround PLLM...
Posted on October 09, 2017 at 19:27I have been trying to get this to work for a few days now, read over several topics here and nothing I have tried has worked... I tried all the suggestions here as wellhttps://community.st.com/0D50X00009XkXWwSAN no...
Posted on October 02, 2017 at 14:59I will focus my question on the receiver board to make it simpler.In the example we are resetting a global flag and then requesting to receive some bytes. Then we wait until the HAL_UART_RxCpltCallback sets the fla...
Posted on October 09, 2017 at 13:40I generate Can code from Cube MX. But i can't receive any data. i just want to receive data on CAN Receiver of STM32F767NI.I try to communicate via PCAN View. When i send data from PCAN-View the program said 'Bus-O...
Posted on October 07, 2017 at 04:50I have the STM32L152C discovery board. I used stm32cubemx to create a very simple bare bones project which will essentially allow me to try out the DFU mode with the PA11 and PA12 pins and a usb cable. I am not g...
Posted on October 09, 2017 at 11:04Hi,I am using SPI1 peripheral as master at 16 MHz on STM32L443, I can send and receive data correctly using DMA.My application requires to speed down SPI to 1MHz during a moment so I changed SPI baud rate on the fl...
Posted on October 07, 2017 at 07:41Is there a utility program available that enables one to create custom screens for the STM32L053 Discover Board? I've looked at a couple of demo programs for the E-Paper display and see that the graphics elements a...
Posted on October 09, 2017 at 11:42Hello,for all families beside F1, the cubemx/mcu/IP/GPIO-STM32Xxxx_gpio_v1_0_Modes.xml give a complete list of the available device functions on a pin. For F1 files, only functions available on a pin that may get r...
Posted on August 04, 2017 at 15:16hi,i have STM32F401 with uart1 configurate in DMA and i would like to add uart2 (in DMA or not)is it possible to do it?how i manage the IT flag?UART1 DMA, call fct :void HAL_UART_TxCpltCallback(UART_HandleTypeDef *U...
Posted on December 26, 2016 at 10:31 Hi all; I try to send by CAN bus to 4 individual motor controllers their pwm speed settings in one go. I found out however, that the first three messages go through perfectly, but the forth message got stuck. ...
