Not quite sure how to best document this problem. But I am porting a current project of mine from an STM32G4 to STM32G0. All of the peripherals are configured correctly and the code base is mature and running well.When I debug the project with no use...
hadc4.Instance = ADC4; hadc4.Init.ClockPrescaler = ADC_CLOCK_ASYNC_DIV4; hadc4.Init.Resolution = ADC_RESOLUTION_12B; hadc4.Init.DataAlign = ADC_DATAALIGN_RIGHT; hadc4.Init.GainCompensation = 0; hadc4.Init.ScanConvMode = ADC_SCAN_DISABLE; ...
I am using STM32H743ZI2. I am using 6 ADC with external timer and dma to acquire data. After I acquire adc data (16bits), I will use scale ratio to obtain physicals value I would like to get. This value will be 32bits. After I do power (a x a), the r...
Hi everyone,First of all thanks for your answers and sorry for my english level.I checked the reference manual of my MCU (RM0468) and I realized that the after reset value of the most GPIO is high impedance.I need to stablish a new after reset value ...
In the STM32L071 reference manual, there is following statement regarding STOP mode entry with HSE as a system clock:"If the application needs to disable the external clock before entering Stop mode, the HSEON bit must be first disabled and the syste...
For a STM32F105 project I have ADC1 configured with13 regular conversion channels.The problem is I only get the first reading and the rest of the buffer stays empty.It seems the pointer to the buffer array is not correct or the DMA is not incrementin...
Hi all,I have a question concerning the duration of float multiplication on the STM32F4. As far as I know, the chip has an FPU.I run the following code snippetfloat LagCompensator_process(LagCompensator_instance* S, float input) { S->x2 = input; ...
Hi!I try to implement HAL_UART_Receive_IT + UART IDLE way to receive data, because I know maximum size of incoming messages. But i don't know size of each message anyway. To achieve this i do the following things:1) Initialize UART and enable global ...
In the case of normal wake-up, about 6~7 mA current is consumed and 100~250uA is consumed when going into stop mode.Sometimes, it cannot wake up from stop mode when it consumes about 1.6 to 1.7 mAHere is my code:HAL_RTCEx_SetWakeUpTimer_IT(&hrtc, g_s...
I set PB7 for the output pin to light a LED when PB7 is HIGH. However, after the function "HAL_SPI_Receive_IT()." is called, my LED doesn't light or turns off even if setting PB7 as output HIGH. I use CubeMX ver. 6.6.1-RC2 and CubeIDE ver. 1.10.1. ...
