I need to do a project where I use the BDMA to transfer arrays from memory to the GPIO. The idea is to send the information in 8 bit parallel at 12.5MHz.I started with the DMA example from the STM32 (called DMAMUX_RequestGen) to try to understand how...
Hello,an4013 Rev. 6 on page 21 writes:"The Counter Enable signal is generated by a logic OR between CEN control bit and the trigger input when configured in gated mode."while e.g. RM0351 writes:"Enable the counter by writing CEN=1 in the TIMx_CR1 reg...
Hi, I'm trying to use the STM32F7 to perform the FFT of a signal connected to ADC1 Channel 0 on my discovery board and I'm having trouble getting the TIMER 2 to trigger the conversion. When debgugging, it seems the DMA function isn't called at all...
I configured the WWDG using cubeMX and the init looks as follow: hwwdg.Instance = WWDG; hwwdg.Init.Prescaler = WWDG_PRESCALER_8; hwwdg.Init.Window = 127; hwwdg.Init.Counter = 127; hwwdg.Init.EWIMode = WWDG_EWI_ENABLE; if (HAL_WWDG_Init(&hw...
I am trying to connect the VL53L1X distance sensor to a B-L072z-lrwan dicoboard so it can send data using the lorawan stack .This is my first project using a hal and i cant get the I2C connection working.The output to my serial monitor is: 536872016...
I need to use the serial usart1 how comunication and receiver data by interrupt
I read from "UM1727 User manual" The STM32 Nucleo examples, applications and demonstration are provided in one single .zip file. The extraction of the .zip file generates one folder, STM32 Nucleo_FW_VX.Y.Z, which contains the following subfolders. I...
Hello,I want to seperate my TX messages with an IDLE frame (all 1) in order to be able the sync to it on the RX side by getting an IDLE interrupt.Is there an elegant way using the USART regs to verify that I send at least one IDLE before staring my ...
Dear Members,I want to read a result from my GPS,it's Neo 6MI initialized 2 UARTs UART 1 for PC and UART 2 for GPS,I got this result :INIT CODE GPS NEO - 6M.... From GPS : Is it receiving properly ?The code : char in[8];pr...
Posted on June 08, 2018 at 11:07Hello everyone!I`m trying to get CDC VCP working on STM2F407VET6 chip. I`ve created a project in STM32CubeMX (the latest version available), where I`ve set up clocks, enabled USB_FS_Device and USB CDC middleware. All ...
