STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
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...
Hello, i try to configure a STM32H7S7L8H6H in CubeMX and it seems that, when Ethernet RMII is configured, SDMMC2 is unusable because there are some pins like PC1 which can't be remapped. Can this be true?This chip is designed for external memories an...
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...
