Hello everyone, I configured TIM1 for pwm. I will use CH3 and CH4. CH4 works well, but CH3 does not work. Sometimes when I load program first time CH3 works, But When I turn off the power and then turn on power CH3 does not work. Is there anyone who ...
Hi,I'm trying to receive data through USART2 through Arduino's serial terminal. I'm not able to receive anything. When I suspend the process, it is always stopping at UART_WaitOnFlagUntilTimeout(); . I'm using "HAL_UART_Receive(&huart2, rx_data, 10, ...
I am developing on STM32-f030CCT6 MCU, and IDE is IAR.There are two program in the flash, one is loader, one is application.Loader is responsible to upload application, and jump to application location to execution.Loader uses timer 6 as time base ...
I want to debug a CubeMx Generated project on Nuelco-L496ZG board.In CubeMx, I created a project with only DCMI and related DMA, and generated the codes.Without adding any other code, I debugged the project in System Workbench for STM32,I thought the...
Trying to use the STMFlashLoader Demo.exe on an STM32F756EVAL. The auto baud detection in the UART bootloader seems to only sometimes work at 9600 baud. I try higher bauds but it fails. And there is no Speed command (0x03) like the CAN protocol has t...
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...
