STM32H755ZI SPI / Proper way to receive data

Hi everyoneI'm currently working with the STM32H755ZI SPI1 peripheral. I'm using low level driver to read 2 bytes of data. I'm transmitting 2 dummy data bytes (0xFF) in order to get some response from the SPI slaves. Most of the time, the receive wor...

Hi i am using nucleo L073Rz board , how do we authenticate a user application bin file flashed in to a board from iap is the correct bin and move on to run.

The problem is crc used in iap for transferring the bin file is to only check for errors during the transfer process , however i dont want any random bin files to be flashed into the flash or executed from it, only certain signed bin files need...

Is it possible to read from multiple ADC channels on Nucleo L011K4 (or on L081KZ)

Hi! I'm pretty new to STM microcontrollers and I found myself in a strange situation:I want to create a prototype for a project on Nucleo-L011K4 (and later use L081KZ for the PCB version) and I need to run ADC on multiple sensors paralel. But all tut...

I would like to design IR thermometer non-contact. Please suggest me as MCU with 48(preferred) or 64 pins, ADC 16 bit, with Timer, SPI, I2C, UART, Program memory 16 to 128kB, Zero-Drift Amplification (optional)

__disable_irq() in ISR possible?

Hello,I have a global variable, wich is accessed by multiple ISRs. Can I safely disable and re-enable the interrupts within an ISR using __disable_irq() and __enable_irq()?Or is there a more elegant way of protecting the variable access?best regards,...

STM32L4 serial communication doesnt work!

hey,i have an STM32L432KBU6 and i want to serial communicate with my chip. I connected the SWCLK, SWDIO and the SWO pin and followed a couple tutorial on youtube but i just cant get the Serial communication done. i just want to open serial monitor li...

I am unable to configure CAN in STM32L476VG Discovery board. I wanted to develop an application which sends CAN message and receives CAN message. I enabled 2 interrupts CAN1_TX_Interrupt, CAN1_RX0_Interrupt. I selected Normal Mode only .

When debugging I found that MX_CAN1_Init() is not getting initialized, inside this code HAL_CAN_Init() is blocked by a while loop.That blocking iteration is as follows/* Get tick */ tickstart = HAL_GetTick(); /* Check Sleep mode leave acknowledge */ ...

Trouble to install the ST link USB driver, it is not installed in the device manager. Jumper JP7 is set to STLK, LD6 is blinking red, LD5 is off?

MCU locks up the moment a relay closes. Are there any tips to stabilize / make the MCU less sensitive to external noise?

We have a board with a STM32G071RBT6. The MCU is controlling a mechanical relay that breaks mains voltage (230V). When the relay closes, this causes the MCU to hiccup in rare occasions: either the core locks up and the WDI resets it, or a NMI excepti...
