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 am beginner and I want to read/write data to SD card via SPI.I do everything according to this instruction https://01001000.xyz/2020-08-09-Tutorial-STM32CubeIDE-SD-card/ and all time get f_getfree error (3)And I also tried to repeat by this instruc...
Hi.I’m working on a Nucleo-411, using CubeIDE, and HAL, and I want to read 4 PWM signals from am RC receiver. That is 4 50Hz signals, with a pulse width ranging from 0.5mS to 2.5mS. I’m following the reference manual, and some examples, and so far I...
Hello, I would like to use the error callback of the FDCAN module on the STM32H743ZI and so far I got it working. Once an error (e.g protocol error) occured the callback keeps getting called. According to the reference manual an interrupt flag can be...
Hi all!I'm developing on a evaluation board NUCLEO-F446RE STM32 F4.I've to read an adc input in order to monitor a battery.There's a lot of unexpected noise in my acquired data, as visibile in attahments.I've tied directly the adc input to Vref and t...
Hi,GreetingsI have a board with STM32G431KB controller inside. i am trying to interface classic can into this controller to have bit rate of 500 kbps. However this particular controller has FDCAN and need to configure as classic can (BxCAN). I am in...
Hi,I want to combine NMEA data from two uart and send it from the third uart.Which way I should follow?
HelloI am currently attempting to interface a STM32L412 with a STUSB1602 TCPC. I am attempting to get this started by porting one of the existing STUSB1602 software libraries for another MCU. It appears like this port could be very arduous and error ...
Hi expert,The lcd on daughter board(MB1314) of STM32L4R9I-DISCO is broken, and is not working.But the other parts of STM32L4R9I-DISCO are all ok. My question is that where can i just buy the MB1314 ? Could you give me the information?Best regards
I have bought some H745 IC. I am sure if they are old or new
I am using the UART4 in DMA mode. But as soon as I initialize the UART in RX mode, I get a framing error that calls the HAL_UART_ErrorCallback Error _Handler which halts the program. Below is my init code./* UART4 init function */ void UART4_Init(voi...
