UWB Pulse

Hi.I want to generate an UWB pulse with 1ns pulse width and period of 1us.then i want to detect it.can stm32 help me to generate this pulse or detect a 1ns pulse ?sorry for bad English!

how can i save the pcm data into the memory using I2S and DMA with STM32F217IG ??

Hi,I'm using STM32F217IG microcontroller with TLV320AIC1106 audio codec for recording and playback.I need to generate .wav file with PCM 64kbps sampling.The codec is able to to give PCM Data of 8-bit u-lawfor this i want to use I2S with 16 bit PCM wi...

Spi read and write on different edge?

Hi,i am using stm32f103 spi read writei have application ic connected to this MCUis it possible to use write on rising egde and read on falling edge for spi communication?currently i am doing both on rising edgeso, write now my write is ok but while ...

Strang debugging observation

Hello AllI am new to this community and, for that matter, to the whole area of embedding programming. So please forgive if my question is trivial.I have created a simple project for F303RE using CubeMx, turning the LED on/off using the blue button, a...

STM32H7 UHS cards problem not reaching full speed of W/R 48MBps/65MBps at second debugging session

Hello, I made board with STM32H7 and i am running UHS example.First time i always get 48MBps write and 65MBps read, but at the second debugging i get only 8MBps read/write speed, and i have to remouve card and insert it again to get back to that blis...

NRST pin driven by flash programming algorithms

It looks like I made a fatal mistake by connecting the NRST pin to the PA0 pin on an STM32F778AIY. This is a part with no internal voltage regulator for the core so the PA0 pin acts like a power on reset. This hasn't caused problems with power cyc...

how to change PWM_Periode in the Code?

Does anyone know if I can change the PWM signal period in the main loop? after initializing the timer in Cubemx?

i worked on stm32f303ze i want to know if it is possible to create file in the 512K flash drive with the stm32f303ze. is there an example or library to do this ? thanks

Extend SysTick to 32 bit / Interrupt-safe DCACHE handling

In my software, I usually extend the 24bit SysTick handler to 32bit with the tricks shown in the code segment below. Using such a do-while construct as shown in "GetSysTickCompleteVal" I usually prefer for the fast access to volatile interrupt data, ...
