Resolved! How can I Analyze LIN Data on car by STM32?
I have a sensor which send LIN message to vehicle, I want to read value of current, voltage, etc, form this message by SMT32. I connect LIN Wire to IO of MCU. How can I connect and analyze data?

Nucleo H723ZG SPI1 interrupt not reading FIFO ( register level programming - no HAL)
Using NUCLEO H723ZG & STM32 CUBE IDETrying to send two 32bit data (0xA & 0xB) via spi1 (only two 32bit words per data pkg)NOTE- set up nucleo to close loop back & connected MISO & MOSI / clk=~2.182MHzSPI1 set to 32bit w/ interruptI load 0xA & 0xB in ...
STM32F4 bricks sometimes
I’m trying to create a CMake build for an STM32F4. Everytime I flash the CMake build the device gets bricked. When I do a full chip erase and flash again with a working binary, it still doesn’t work. Note that this second binary was working before bu...
Resolved! STM32H7 HAL usart with and without interrupt
Using an STM32H723 I started with a non interrupt USART connection onto a wifi module.I set up the connection on UART3 implementing nothing more than that and using these instructions int len = sprintf(tx_buff,"AT+GMR\r\n");HAL_UART_Transmit(&huart3...
Resolved! Do all FPU operations proceed in a single SYSCLK tick?
This should be simple, but I can't find documentation. I am running an STM32L4P5 at max clock speed (120 MHz), and I have moved all code to SRAM so it is running with zero wait states. I have an extensive calculation to do using the FPU -- I am ...
STM32H755 I2c BDMA BUSY ON SECOND CALL
I am having issues with BDMA on consecutive transfers, the DMA handle is always in the busy state on the second call. I call this from my application and first transfer works as expected, goes into ISR void HAL_I2C_MemRxCpltCallback(I2C_HandleTypeDef...
ADC Sampling Does not look correct NUCLEO-G474RE
My system clock is 170 MHz, and my ADC1 clock is asynchronous with a prescaler of 4. This would mean my ADC1 frequency is 42.5 MHz. I have the ADC being triggered by a timer that is fed off the system clock and triggers every 1 millisecond.ADC config...
Resolved! Where is ETH_PHY_INTN
In the reference Manual of STMH730, on Table 543, page 2825, there's a Port "ETH_PHY_INTN" listed. Where ist that port? Or where can I configure the GPIO to use for it? I cannot find anything in the datasheet.
SPI MX config buggy?
Hi, i try migrate some old stdlib app into HAL or LL over new project in MX. On old system we have SPI init part for TX only master /* SPI configuration -------------------------------------------------------*/ SPI_I2S_DeInit(SPIx); SPI_InitStruc...
Resolved! STM32F405 TIM1's repetition counter
I have a question when I read the reference manual of STM32F405, and it says that "for odd values of RCR, if the RCR was written before starting the counter, the UEV occurs on the overflow (which should be underflow as I have seen in TIMx_RCR funct...
