STM32 MCUs Products

hello everyone i am new in programming with the stm32 nucleo and since i tried to program the rfid with the stm32f302r8 please can someone help me with a code

I want to know if anyone can let me know where in the world are their companies that actually stock STM32F303K8T6 MCU's, I'm looking at mouser and Digikey and they are out of stock now for over a year but the delay is permanent set at 54 weeks.

STM32L4 - DMA with SPI in slave mode doubles the first byte loaded into DMA

We are migrating from STM32F103 to STM32L4. The code architecture is the same, as the product basically is the same. We just upgrade the micro. We have an SPI that is configured in slave mode, and a device that supplies clock to the SPI. DMA is u...

NUCLEO-F446RE board firmware burning.

NUCLEO-F446RE board has 2 MCU. One is on the upper side(STM32F103CBT6) and the other one is on the downside (STM32F446RET6U). When we burn the firmware code, the code comes from DP/DM and goes to the upper one(STM32F103CBT6). Afterward, the upper one...

Hi team, HAL_I2C_Mem_Read/Write_IT is not responding when calling it as function into a main file from another file. How can i get an output after read/write in the below detailed case?

I am using STM32F411VE for testing I2C driver, in which i have defined 9 test cases using HAL_Mem_read, HAL_Mem_write, HAL_Master_transmit and HAL_Master_Receive(inblocking and non blcking mode(IT, DMA)).  I have defined each test cases as a function...

ADC output with offset in some unknown region

We are migrating project from F303 to G473, but the ADC output of G473 confused us with a strange problem, and with same circuit with F303 project below:sampling time: 66nssampling period: 1.16usvoltage range: 1~3VVdda / Vref: 3.3VHere is thre proble...

Clear SPI TX FIFO

I`m working with STM32G0 and SPI in slave mode.Is it possible to clear TX FIFO buffer without any master`s clock?In HAL library there is a function called "HAL_SPIEx_FlushRxFIFO", but no method to clear TX FIFO,

What is the best/easiest way to communicate between 2 STM32's (SPI,I2C, ...?)
