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...
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...
Hello everyone,Dev Board based on STM32L4R5I am just trying to erase and then write something on the internal FLASH.I am trying to follow the example: https://github.com/STMicroelectronics/STM32CubeL4/blob/master/Projects/NUCLEO-L4R5ZI/Examples/FLASH...
Hello,i am pretty new to this topic. I want to send simple data via CANFD from the stm32H/53AI to a PC. For that i have the CANFD-USB adapter from PEAK and to display the data i am using PCAN-View. I discovered the function and i put in the addresses...
