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...
Hi everyone,I'm currently using the Nucleo F429ZI development board to test SPI Receive, and I've encountered the following two issues:I use the HAL_SPI_Receive() function, when I config the SPI frequency to a slower rate, I've observed that the CS s...
I have timer 1 to use with hall sensors as interfacing timer. Timer 8 is then used to output the signals (see picture red and blue).The simulated hallsignal (3 sensors combined) is very precise and pretty constant (green signal - second box)."A" show...
RM0444 (Rev. 5 Nov 2020 - should be newest): Chapter 15.8 Oversampler: "N is defined using the OVFS[2:0] bits": this should say "OVSR[2:0]" bits. Chapter 15.12.3: Register ADC_CR Note for AD_EN: "set ADEN only when all bits of ADC_CR registers are 0"...
Hello, I want to use the HSE of the NUCLEO-H743ZI2 development board. I tried to set it up according to the instructions in the user manual using MCO from STLINK-V3E.Here's my setup:However, when I checked STLinkUpgrade, I found that the HSE is set t...
Hello everyone!I'm working on a project where I want to transmit some data to the cloud using the STM32H7B3I-DK board. However, I've encountered difficulties in establishing serial communication with this board. I've tried enabling SPI communication ...
Hi,I'm working on a hardware design using the STM32F765VIH and I am trying to connect a MT28EW128ABA1HPC-0SIT NOR Flash and IS66WVH16M8DBLL-100B1LI PSRAM to the FMC in muxed mode. I'm struggling to understand how the muxed connection should be made a...
i'm trying to get a 3 channel dma up and running on my u5, but unfortunately i keep getting the error handler at line 122 that the a/d can't start via dma. do i need to do something additional here or not? i've already clicked through some posts and ...
Folks, I started off with the H573i discovery board demo as reference for the MSC + SD card (with ThreadX). I don't have the Discovery board since in my application I needed those CC1, CC2 USBPD pins for something else. So I ran a board of my own (u...
Hello,My final goal is to output two pulses from two separate pins, but not at the same time. My intention is to use TIM1 for my STM32F401RE board, as this is the only timer that allows me to set the repetition counter for the 'One Pulse Mode'. This ...
Hello,I would like to get free memory on USB drive (64GB, FAT32) with FatFs library. Here is part of my code: DWORD fre_clust, fre_sect; uint64_t free_memory; res_file = f_mount(&fs, "0:", 1); res_file = f_getfree("0:", &fre_clust, &fs); fre_sect =...
