Double signal on PWM driven by DMA

Just trying to set PWM with DMABuffer which I try to use as duty cycleuint16_t BUF_DMA[6] = {3, 4, 2, 7, 9, 1}; PWM is started by buttonHAL_TIM_PWM_Start_DMA(&htim1,TIM_CHANNEL_4,(uint32_t*)&BUF_DMA, 6);Output I getI can't understand why BUF_DMA[3] ...

STM32CubeMX suggestion: be able to flag a driver to not be overwritten upon regeneration

In some cases the USER sections are not sufficient to make some needed modifications to the HAL drivers. When modifying a configuration in STM32CubeMX, it would be useful to be able to flag drivers so that they are not overwritten when the code is g...

Mounting USB using fatfs

Hi all,I am having troubles mounting a USB using the "f_mount" function in the fatfs library. My usb does mount but only after many attempts, using a simple counter I have found it to be 81, every single time I run the code it is the same amount of a...

Usb otg conflict with i2c on stm32f4 board?

I have the stm32f429 discovery board and I'm experiencing a conflict between the usb otg hs and the i2c3. I use the cdc usb library which when initialized on it's own works fine as a virtual com port and I can communicate in windows. When any other c...

Wave generation of particular frequency.

By using timer I want to generate a wave of 27Mhz frequency. Present time I can generate only 13.48khz frequency wave. My timer settings are below please tell me how can I generate it.static void MX_TIM2_Init(void){ TIM_ClockConfigTypeDef sClockSourc...

Unable to getting interrupt on rising edge

I am using STM32F103C8T6 and STM32CubeMX and TrueSTUDIO for development purpose.I am trying to get interrupt on rising edge and in ISR I wrote LED blinking code.I gave high input for rising edge detection but not getting LED blink.My code as follows...

STM32CubeMX configuration limitation (greyed out options)

Hello, friends!I configured the project for STM32L011 Nucleo board for read ADC input and I noticed that some of frequency devider options were greyed out for some reason).However I tried to change this setting in the c file with 100% success:At leas...

Not receiving data on PC com(RS232) port, when transmitting data from STM32F407VG DISCOVERY board (Using Baseboard STM32F4 DIS-BB RS232 port ie COM1)

Hello,I am facing trouble in sending data out from STM32F407VG Discovery board (connected to base board) using UART6 (J1 and J2 jumpers are connected). Connected the Tx pin of RS232 port on baseboard to PC COM port Rx pin and sending data periodicall...

I would like to know if ST provides support for NuttX, the embedded OS that is POSIX compliant. I am wondering if there's an STMCube-like codebase of drivers or some sort of manual for getting started with NuttX.
