Posted on May 30, 2018 at 11:27Hi,sorry, if this forum is the wrong place, but I did not find a better one :)In AN3155 (USART protocol used in the STM32 bootloader; DocID17066 Rev 7) on page 7 it is written:2. for each command the host sends a byte ...
Posted on May 30, 2018 at 06:24Hello ST engineers,I have some questions about ADC of MCU STM32F302RC, please help to answer.In our application, operating voltage of MCU is 3.3V (VDD=VDDA=3.3V). In firmware, we want to use VREFINT of ADC to calculate...
Posted on April 23, 2018 at 13:28Hi,I am developing a custome board with the stm32f427.I cannot get the USB to connect to the PC. I allways get the number 43 error 'USB device unknown'The builtin bootloader is loaded and I can see the code running o...
Posted on May 30, 2018 at 05:45Hi ! I have designed a board with stm32f765 (LQFP100) but I got a problem with it when I test this board. I connect the board through usb cable with st link v2 and the ST Link Utility can detect this stm32f7 but when I...
Posted on May 30, 2018 at 03:57I am using the STM32F7-Discovery board and have been stuck at trying to enable the DWT cycle ,From what I've seen online this should suffice for enabling it:#define DWT_CR *((volatile unsigned int *)0xE0001000)#define ...
Posted on May 30, 2018 at 09:43Hi all, I am using a board with and STM32L476. ADC 1 is used in software triggered mode, with DMA (8 channels). (So firmware dictates when to start conversion, DMA interrupt tells the firmware to process the data.) Thi...
Posted on May 25, 2018 at 09:34Hello Everyone,I,am having a issue with my can node.The communication bw two can nodes built on STM32L4 works perfectly fine. But that's just for testing purpose. I don't intend to use it that way.When I introduce it t...
Posted on May 24, 2018 at 15:10When I disable TCP of the lwIP in CubeMX and set the MEMP_NUM_TCP_PCB to 0, I can't compile without error MEMP_NUM_TCP_PCB has to be > 0.Seems like a bug?
Posted on May 26, 2018 at 11:57Hello! I'm using stm32f746igt. You can run the program in sdram on this controller and use Chrome Art to display the image on the display.
Posted on May 07, 2018 at 11:34Hello all,I am really new at all this, I hope someone has a simple example to help.I am trying to receive 9-bit data using the STM32-F103 in normal polling mode example code belowuint16_t messages[30]; HAL_UART_Receive...
