The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Posted on January 04, 2017 at 12:53I have a Nucleo-F446RE Eval Board with a STM32F446 RET6U. I use the SPI2 peripheral. When I switched from baudrate prescaler 4 to 2 I get problems with the SPI status flag 'Rx buffer not empty': The last flag does ...
Posted on January 04, 2017 at 20:25I am not sure why the following code is not working. I have used it before for a different pin, but I believe my modifications would allow this to work? I am running the code on the stm32f051 discovery board using ...
Posted on September 04, 2015 at 23:22Hello, I recovered some examples to display some string on my DISCO-BOARD, but the example that I found are all build with Drivers/BSP/STM32F429I_DISCO which use as source and header files ==> stm32f429i_discover...
Posted on January 05, 2017 at 13:32Hello,I am new to CAN and I was trying to understand how the HAL CAN APIs work. Based on my understanding of CAN 2.0 standard each data frame should have CRC field. How is this handled in bxCAN? Am I misunderstandi...
Posted on January 05, 2017 at 15:20In my project (F415RG) I'm running timer paced single channel ADC sampling with DMA transfers and Analog Watchdog coupled to the same ADC channel. When an out of window voltage occur I need to momentarily stop the ...
Posted on December 30, 2016 at 13:40hello dear forum,I am trying to take 500 samples from STM32F103RC ADC with DMAI wanna know if the ADC sampling clock equal to ADC clock or system clock for example ;If I choose ADC clock = P2clock / 8 = 9 MHz and ...
Posted on January 04, 2017 at 19:52Hi everybody.I have to implement a Wiegand reader on a STM32 demo board.Using CubeMX I have defined 2 gpios as GPIO_EXTI and now the HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin) is triggered.The problem is that the ca...
Posted on November 22, 2016 at 09:43Hallo,I am trying to solve this problem that I am facing with ADC and DMA use.I use a STM32F303 Microcontroller, with CubeMX vers4.17 and Eclipse.I was able to test and use all the peripherals I needed but I encou...
Posted on December 20, 2016 at 19:20Hi,I'm working on 3-Wire(PF7-CLK,PF9-MOSI,PF8-MISO) SPI (SPI5, slave mode, direct mode) using a STM32F769-EVAL.My goal is to transmit data from SDRAM buffer thru SPI to SPI-MasterI'm using 'HAL_SPI_Transmit_DMA' f...
Posted on January 04, 2017 at 00:52 Hi Guys, I am transmitting two bytes between two nucleo boards on uart1 and only receiving one byte (one charachter)? what could be the problem HAL_UART_Receive(&huart1,(uint8_t *)data3,5,10); void MX_USART1...
