Resolved! STM32G474 - AN5305 Digital filter implementation with the FMAC

Hi All,Is the source code for the Application Note AN5305 Digital filter implementation with the FMAC using STM32CubeG4 MCU Package available ?Thanks,Manu

what will be the problems of using Single VDD Pin (48PIN) connect to VDD voltage by keeping other VDD pins open ?

I'm using STM32f030C8T6 controller 48pin package ,i want to know what are the difference between digital power supply pin and complementary power supply pin . and also need to know that can i use only Digital power supply to VDD voltage for running t...

Emulated UART - Timer triggered DMA for reading GPIOB->IDR in STM32L433RBT6

Hello,I am using STM32L433RBT6 for receiving data from NEO6M GPS module. The requirement to add the module was given after the circuit board was delivered. Hence, I need to implement the UART reception using emulated uart (bitbanging technique). I ha...

Resolved! Nucleo-F446RE board cannot be flashed after being removed without disconnecting removable disk

Hi, every time that I plug in my Nucleo-F446RE board a removable USB drive also appears (I'm using macOS Catalina 10.15.5). If I unplug the board without unmounting the USB removable disk that appears when it's attached then I have a 90% chance that ...

I2C help please.

Hi everyoneI have a STM32F401RE Board and I am trying to get the I2C to work with an MPU6050. I have seen some examples but since I can not seem to find PB11 I realized I have to use PB3 as I2C2_SDA pin and PB10 as I2C2_SCL pin. The clock on this is ...

Resolved! A nother STM32G071 bare metal question on SPI

Hello,here is another bare metal question on STM32G071. I am trying to get the SPI to work. But it is not generating any clock signal or MOSI signal. Here is my init code trying to get it to work on GPIOB 6 to 8:void init_spi(SPI_TypeDef* SPI) { if(...

Differential ADC to measure voltages above VDD ?

When using differential ADC, it is safe to to measure voltages above VDD ?I am trying to measure a voltage different across a current sense resistor from 12VDC power supply.

LPTIM repetition counter not work

Hi , I am trying to use lptim on NUCLEOL412RB.I want to use lptim repetition counter to fire a interrupt which period is 5 secs.My lptim clock source is 32k LSI.Here is my config:hlptim1.Instance = LPTIM1; hlptim1.Init.Clock.Source = LPTIM_CLOCKSOUR...

NOR Flash memory Quad SPI initialization

Hello,i need to use this flash memory with Quad SPI. I read the STM32 user manual and some examples of random evaluation boards.I think that this first step initialization should be okstatic void MX_QUADSPI_Init(void) { /* USER CODE BEGIN QUADSPI...

Resolved! Two questions on I2C flags SB and BTF in STM32F446RE

Hi, I'm stepping through the code on Nucleo-F446RE board and doing the following:LL_I2C_GenerateStartCondition(I2C1); step++; while(!LL_I2C_IsActiveFlag_SB(I2C1)); LL_I2C_TransmitData8(I2C1,BMP180_ADDRESS_WRITE); step++; while(!LL_I2C_IsActiveFlag_A...
