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...
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...
Hi gang. My application uses from 0 to 3 UARTs, or maybe USB CDC instead ... LOTS of end-user settable options. Even before I get to that, I'm not happy with my queue implementation that's to be used with UART (or CDC) Tx and Rx. I would love for th...
Hi im using a stm32f205retx (LQFP64)I am measuring 3 adc imputs + Vref + internal chip temp sensor.The temp sensor is the only one wildly oscillating.
Hello ST community,I use a STM32F767ZI-Nucleo. There is a timer generating interrupts every 20ms. If a timer interrupt occurs I use HAL_SPI_Transmit_DMA to send some data. I monitor the return value of this function and after some time of sending wit...
Hi All I am trying to build a custom board (for the first time :)) using an STM32L053C8T6. The board will power an LED and do short burst measurements of its reflection off a strip (< 1s). I am trying to power up the board using a photovoltaic cell a...
Using STM32F746, I want to access Intel's 10AX032H2F35I2SG FPGA.During FMC Configuration, I do not know how to calculate and write the following parameters.I've seen the RM0385 documentation, but I don't know how to calculate it.I have to do it by to...
