As titled, with little definition, how do I configure the NVIC_Type struct ? Directly use the numbers that are difficult to maintain later? Or in fact they have official definitions, but they were hidden somewhere else ?And another question, where ca...
I use the UART RX DMA mode to receive the data from the peripheral. This peripheral could endless send the data after powering up. However after serval rounds UART IRQ handler execution, the UART port couldn’t enter the IRQ handler anymore while the...
I Want to use the TIM2 with two channels in "Input capture mode". CH1--> PA0CH2-->PA1 Now I have two trigger pulses which I will connect to PA0 and PA1, Signal at PA0 will start the TIM2 and signal at PA1 will stop the TIM2.So how I can get the count...
I am trying to use one of the Firmware Package demo projects using Keil v5. With the STM32F072 Discovery Board connected, the Device Manager shows the STM32 STLink driver is working properly under Windows10. In particular, I've loaded the DAC_SignalG...
Hello?I am a developer using the nucleo-f411re board.I had a problem while trying to update the firmware by cutting the st-link part. The firmware is uploaded successfully, but the result of the printf function is not printed on the serial monitor.Is...
My board is STM32F103C8T6.I am generating complementary PWM using TIMER 1 with DMA for changing duty cycle.to be precise SINE WAVE PWM (or SPWM) using CENTRE ALIGNED MODE 2.Now i also want to generate SQUARE wave from channel2 , the wave should have...
This is a question I posted on Reddit a long time ago, but it hasn't been solved yet, so I'm asking here.I solved the dlc value in the notepad picture.And there was an error even though I connected the rs pin afterwards.I want to know the solution to...
We are trying to implement the SPI interface on a STM32G070 MCU using DMA and no interrupts. MOSI MISO and SCLK all work fine, but the NSS signal does not behave the way we want it to. What we need is a precise change from 1 to 0 signaling the start ...
HiI am trying to implement dual bank booting on a stm32G474VET6 and im am doing the flashing of the other bank via Intel HEX decoding from an SD card. In order to test if I am successful, i have flashed my software via cubeprogrammer from the same he...
