Timer resolution question

Hello,I have a project in which I use an external timer module. I want to measure the time that a function takes. I have a function say _time returnTime() which is configured in such a way that it returns a time with 10 microsecond resolution. In the...

eMMC, what is the proper way to detect when a multiple sector write or read is completed?

We have a custom board with an STM32F469 and a SanDisk iNAND 7250-I 8GB eMMC. We have our HCLK set to 168MHz and SDIO clock at 48MHz, 8-bit data width. Using CubeMX (v4.26.1), the user is responsible for supplying the necessary code in the user_diski...

complementary pwm for 6 step commutation

I am driving bldc motor using my bldc driver, I use stm32f103xx as MCU. Using 6 step commutation the control was ok, and i driven in e-scooter using my driver. But there is a small problem at starting, once the motor gets its motion it goes good. So ...

Program flow gets stuck. Why doesn't CC1IF Capture/compare interupt flag gets set, while debugging the next program on my STM32F723E-DISCOVERY?

A while ago I received an STM32 discoveryboard as a gift, after I told some people on a fair that I'm a software engineer. Because I'm allready experienced in C/C++ but new to embedded software engineering, I ordered a course. Now I get stuck on the ...

i am using stm32f030c8 mcu, and got stuck as my rfid connected on spi1 is not working, few days ago it was okay tested with same code .

during debugging i came to notice that after PCDinit() ,few instructions contating read and write on rc522, is receivng correct data through spi but after that it always read zero. same problem had been arrived earlier too but it started working on...

STM32MAT: ADC in Injected Conversion Mode triggered with TIM1

Hello,I try to trigger a ADC for example ADC1 in injected conversion mode with the Timer out event of TIM1 but it doesn`t work. For Time 1 i select OCREF and OC6REF as trigger event. In my ADC I select the Timer 1 Trigger out event as external trigge...

STM32F401 Super Simple SPI DMA does not work or transfer any data

I have been banging my head against the wall for days on this one. I'm using STM32CubeIDE 1.1.0. I create a simple project with a SPI interface and DMA. I'm attaching the full project. I call one function: MX_GPIO_Init(); MX_USART2_UART_Init(); ...
