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...
when i use HAL_QSPI_Receive() in debug mode, always "internal command error". I found this MODIFY_REG(hqspi->Instance->CCR, QUADSPI_CCR_FMODE, QSPI_FUNCTIONAL_MODE_INDIRECT_READ); will cause the error. but i do not know how to correct。
Hi!I'm trying to enable DAC and PWM so they can give out current, but nothing happens. I have tried to connect a simple LED to the pin, but non of the DAC nor PWM pins light up the LED.First of all, here is my init for TIM2, which has PWM enabled.I e...
In stm32f042g6 CAN rx Interrupt is not fired requently,How i will reset the interrupt flag so it will receice data frequently on interrupt?i am facing FIFO0 overrun error (CAN process is ongoing )How to overcome this error to receive the data frequen...
We are designing a control board by using STM32H743VIT6 and STM32F103C8T6. But there is no stock available for these two STM products in any electronics part suppliers. Without these parts, we could not move further with the designing process. Theref...
Hi!I measure the frequency signal on the input of STM32F373. General Purpose Timer in Input Capture configuration is being used to do so. But when the rising edge width of the input signal is around 110 ms, I detect some extra, unexpected pulses. I s...
I want to move the isr vector table to SRAMRelated to this questionI moved my isr vector table to SRAM (linker script)Now i want to aliase the memory addr of 0x0000 0000 to be found in SRAM.In order to do that i believe i need to change the bits from...
Is the below calls are required between every transmit and receive call, if we are using DMA? if(HAL_UART_DeInit(&UartHandle) != HAL_OK) { Error_Handler(); } if(HAL_UART_Init(&UartHandle) != HAL_OK) { Error_Handler(); }Please give a clarificat...
On my board i use USART1 and USART3 to connect my device to other by dual RS-485. 485 tranciever connected to MCU throw digital isolator (4 tx, 2 rx SI8662). If 485 line of USART1 not connected ti device i can start debugging in Keil without problem....
I am designing an UltraLow-Power product around the MCU STM32L412. I need to help clarifying the GPIO states during Standby. Specifically, if the Schmitt trigger is ON or OFF during Standby. This will impact my electrical design if I need to have ...
Hi, I'm trying to capture the period of a waveform without using an interrupt as the frequency will be up to 100Khz and will impact the system operation.Currently I have the timer set up with interrupt on negative edge and record the captured value a...
