How to know that MCU is genuine
I bought 960 MCU very expensive.but many barcode and number has been deleted.I just wonder that this mcu is genuine or not

ITM functionality does not works in STM32L432KC ?
Couldn't use ITM for printf like debugging in STM32L432KC Nucleo 32 board
DMA1 CCR register is NOT updated (NOT Written)
Hello and Happy New Year 2022,I'm using STM32L072, I set SPI1 to be in "Transmit Only Master" mode, and DMA1 as SPI1_TX (DMA1 Channel 3)I use CubeMX to Auto generate my codeThe relevant SPI1+DMA1 line is: HAL_SPI_Transmit_DMA(&hspi1, (uint8_t *)aBuff...
Has anyone experienced this situation?
I have 2 types totally 4 boards (each type 2) of F103C6T6, I programmed them by ST-Link mini through CubeIDE, any of them could be only programmed once, the next time it would be prompted device could be found in CubeIDE. I mean is there any mechanis...
Hal_SPI will be an Open Drain output will appear in the first cycle of initialization
STM32F103STM32CUBEMX V4.25.1The slave device on my side is a fake PP output. It needs a pull-up resistor. I know this is not in accordance with the SPI agreement, but there is no way. When I run the HAL_SPI_Transmit() function, an incorrect pull-up s...
Audio spectrum with onboard ADC DMA
How to calculate audio signal from ADC in DMA using FFT to display on LED 10x10. I have STM32F411 DISCOVERY and connected left and right (2 channels) audio from smartphone. I found this guy https://www.youtube.com/watch?v=3WF4CGKoMas but his code opa...
Resolved! F401RE Nucleo UART_Printf example produces faulty formatted serial output bytes for ODD parity, but correct for parity NONE and correct when changing settings to 9 bits while receiver is at 8bits.
Hello,During my exploration of the F401RE board, I tried to make the uart_printf example work correctly.Capturing the output of the main MCU via CN3-RX pin to a PicoScope 5440, an CH340 and on board F103 USB interface MCU all lead to the same conclus...
Has anyone transcoded the SHT30 Sensor for STM32L0 or any series? I didn't know how to adapt the I2C pins while exporting the libraries. For example how can I adapt these parts from arduino to stm32?

Resolved! Merry christmas to everyone around here.
Thanks for all the support, see you after holidays.:evergreen_tree: :snowman_without_snow: cheesy caption
I am trying to read UART and to hold on rx_data array. when I send "AT" to rf module it returns "OK" , but on my code I cannot receive anything from UART. and help appreciated
uint8_t tx_data[2] = "AT"; uint8_t rx_data[10]; HAL_Delay(1000); while (1) { HAL_UART_Transmit (&huart1, tx_data, sizeof(rx_data) , 250); HAL_Delay(500); HAL_UART_Receive(&huart1,rx_data, 20,1000); HAL_GPIO_TogglePin (GPIOA, LED_Pin); HAL_Delay(...
