Can anyone please tell me the difference between VDD,VBAT and Voltage regulator in stm32f407vgt6 discovery board

Why does UART accept the signal without any failure in one conditions and doesn't accept the signal at all in the other conditions?

Hello.I have assembled the device on the STM32L496ZGT6P microcontroller. Along with the other functions, this controller is to poll its UART interface (more precisely, UART4). The device is operated outdoors and at low temperatures, and I have notice...

Why I am not able to get Half conversion complete call at my 700 samples complete? I am missing anything?

Hello everyone,I am using ADC + DMA + TIMER for my analog samples on STM32 nucleoF401RE.I am new into the STM32 family.So I refer some code as per given some examples in this community.But I am not able to achieve it.I wanted to follow below method f...

I have stm32f407vg discovery board. I could program my board successfully before but now my pc can't recognize debugger. What should I do to fix it?

Use DMA with SPI acting as a (simple) shift register?

I've (sort of) found out a way to store GPIO states in memory with DMA (parallel data input from a 74HC595 shift register, because the STM32F103Cx doesn't have 4 SPI peripherals) and I want to output that same data via SPI in a similar manner, except...

problem with Soft AP on L-475-B IoTA2

hi everyone,what's the problem with AP on the IoTA2, I can't set an AP, everything works great only the AP doesn't work?can someone tell me is there Something with the fw?

What commands should I send through the Serial COM port to a Nucleo-F401RE board via a Python Script and Command Prompt to replicate the Connect and Start options in Unicleo-GUI?

Hello All,I am using a NUCLEO-F401RE Board and a IKS01A2 Sensor Board with it. I want to collect the incoming data dynamically and modify it. By using Unicleo-GUI and just clicking Connect and Start I am able to observe the collected data. I want t...

Timer: No complementary output in one pulse mode?

Does one pulse mode offer the complementary output? My complementary output just sits there. I'm on TIM17 and I'm not sure if being on the 'lite' timer is the problem. I suppose I'll try moving it over to TIM2 and see if the problem persists althou...
