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...
Hello, does anyone have any simple code for interfacing a digital microphone with the Serial audio interface? The MEMSMIC1 example project seems too complicated to start with. I am using the stmwb55rg nucleo board
Hello,I am using a STM32H743 with a W25Q128 external flash memory running FreeRTOS and FatFs. USB is configured for mass storage, to copy files from a computer to the flash memory. The following function is used to list all the files and directories ...
I know there are hundreds of posts about this and I've been through most of them but still can't get things to work.The concept is simple: set up 2 Nucleo F446 boards, one as full duplex slave the other as full duplex slave.Master pseudo code:while 1...
I am using CAN peripheral and for debugging I am using USB-CDC to receive the status of the CAN transfers and Reception. The issue I am facing is The USB was recognized as Virtual Port when Only USB was initialized and used but when Implemented with...
I have I2C working properly, but can't seem to figure out how to recover the bus and get it to working again if I test for the presence of a device that is not on the bus and therefore I2C_Mem_Read() returns HAL_ERROR. There are other devices on the...
Hi I am trying to run FREERTOS enabled USB CDC Host on my device having STM32F756 MCU.My firmware package version is v1.17.1 which I think is the latest version for the F7 series. For this what is the latest version USB CDC Host Drivers which is supp...
Hello, I measured my SPI transmission takes ~600 CPU cycles @ 250MHz, so it's about 2,5us to transmit 2x 8-bit array.I'm using HAL (cube IDE). How can I speed it up? I need to make 4 transmissions like this, so it's ~10us. I need it to work with I2S,...
Hello,I've made a custom board using the Zephyr SDK and a STM32L081 soc. I would like to flash my board using a JLink Debug prog with OpenOCD and GDB.Compiling works fine but when it comes to using my openocd.cfg file as support for my board, I get t...
Hi, im trying to work on external Flash with filex and levelx, and the external flash chip is "IS25LP064D ". i was trying to configure the OSPI, in the memory type other than micron, macronix, AP memory and Macronix RAM. I'm not able to see any other...
测试故障如下：1. 故障现象：不上数据，不能进入网页; 测试步骤：1.拆回设备2.通过网络连接网络拾音器网络1，能ping通，进入不了网页。连接网络拾音器网络2.能ping通，能进入网页，设置完IP准备连接服务器，发现网页有连接不上了4.通过串口看，发现程序没有跑起来。通过反复上电，发现程序每次跑的结果不一样，有时一上电就死机，有怀时能跑几士秒5.好、坏板子互换芯片(stm32)，坏板子更换序号为0x42-0x00-0x35-0x01-0x57-0x46的芯片，工作24小时一直正常。好板子更换0...
