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...
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...
I see that Keil is using .FLMand .stldr looks like CubeIDE are those the same ?can I change the extension from .stldr to .FLM and load using Keil and vice versa ?also any idea how to add the loader to keil ?I see that Keil has a lot pre defined loade...
Hello, I would like to pick an MCU based on ETM version available on it. This is needed to try out Orbtrace Mini tracing device. It is stated that its currently support ETMv3.5, also i am willing to test lower ETM version and higher too to check the ...
We have a custom PCB with a STM32H750 on it with Dual NOR Flash (W25Q12BJVSIM). I have been able to flash the code on all but one board. When I attempt to flash the board with STM32CubeProgrammer, I get a Warning: The core is locked up message. How d...
