How to receive using UART to a precised byte

Hi ! I am receiving data through UART using DMA to a buffer of 10 bytes. I want to always receive to the uartBuffer[0]. Thank you!

How to implement PLL in STM32?

I am trying to implement a Phase Locked Loop in a microcontroller STM32. I have a reference signal and feedback signal which has $\phi$ difference wrt reference signal. For the moment, I am not using a real time feedback signal, rather simulating it ...

Resolved! ADC1 in STM32H753 gets 0xFFFF as the digital value for HAL_ADC_Start & HAL_ADC_Start_IT & HAL_ADC_Start_DMA.

I use ADC2 and ADC3 (with HAL_ADC_Start_DMA) with no problem, just having problem with ADC1. I'm using FREE-RTOS. STM32CUBEIDE.

STM32L412CB Flash Write/Erase fails first time only, then works OK.

uint32_t write_to_flash(uint8_t * buf, uint16_t length){ if((length)>2047) return 0xFFFFFFFF; uint32_t base_addr=0; base_addr=getHexAddressPage(DATA_PAGE); uint32_t PAGEError; /* Unlock the Flash to enable the flash control register access ...

Glitch value for DAC in the STM32G071

Hello.I can't find Glitch value for DAC in the STM32G071 documentation, and also what type of DAC is implemented in the MCU: R2R, resistor string, etc.Where can I find the information I need?

STEPPER MOTOR using I2C

Hi, I have a problem with starting a stepper motor using the I2C bus. It uses the NUCLEO-F746ZG microprocessor, the SMC 64-BP stepper motor driver and the KH1634-03CA stepper motor. The main problem is finding the address of the controller and giving...

How to reduce the consumption of the Nucleo-L073RZ board to less than 700uA? How to disable J-Link part on the board?

I am developing a card with a supercap storage, I designed it for a consumption of 40uA as it is written in the datasheet, however I reach only 3mA and I use the "standby" mode written and found on the internet. Can you explain me how to disable the ...

Resolved! Hi..I am using STM32U575 NUCLEO ..there are three drive levels are mentioned for LSE...which one one should be used or which is more suitable for low power consumption and I need to know the power consumption in each case (numerical value)..

In the errata sheet,it is mentioned that low drive mode and medium low drive are not working.. but I checked and they work fine...is there any correction in the errata sheet...?..Can I go with low drive mode for LSE (NUCLEO-U575ZQ)???

FMC behaviour if read before a previous write cycle has completed

I connecting an FPGA slave to an STM32F7 FMC 'sram' bus. For this particular project, I need to access the bus both inside and outside of an interrupt. Because there is a write FIFO, can I assume that writes are atomic and don't require mutual exclus...

How should I study STM32 MCU

Hello,I am a mechanical engineer that is studying Mechatronics as master degree. I am getting keen on embedded system after I have taken a course on operating systems on embedded systems. I have never used STM32 word and I have just received a stm32f...
