Hello everyoneI'll receive soon a custom board based on an STM32 microcontroller (still not sure about the specific part number) and I'll have to flash FW updates on it. A few questions about it:1) There's a 4 pin header connector on the board (VCC, ...
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?
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 ...
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...
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...
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 ...
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...
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...
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.
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...
