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...
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...
我们这次购买的芯片上没有ARM标记，右上角的版本号改成了二维码的形式。 请咨询我们的供应商，不同的产地/包装厂/批次会有所不同。但是我们的质量部门不会库存它们。 标记的变化比较大。此标记更改是否有相应的文件？ Translation: There is no ARM mark on the chip we purchased this time, and the version number in the upper right corner has been changed to a QR ...
Hello everyoneI'll receive soon a custom board based on an STM32 microcontroller (still not sure about the specific part number) and I'll have to flash FW updates on it. A few questions about it:1) There's a 4 pin header connector on the board (VCC, ...
I have a sensor which send LIN message to vehicle, I want to read value of current, voltage, etc, form this message by SMT32. I connect LIN Wire to IO of MCU. How can I connect and analyze data?
Using NUCLEO H723ZG & STM32 CUBE IDETrying to send two 32bit data (0xA & 0xB) via spi1 (only two 32bit words per data pkg)NOTE- set up nucleo to close loop back & connected MISO & MOSI / clk=~2.182MHzSPI1 set to 32bit w/ interruptI load 0xA & 0xB in ...
I’m trying to create a CMake build for an STM32F4. Everytime I flash the CMake build the device gets bricked. When I do a full chip erase and flash again with a working binary, it still doesn’t work. Note that this second binary was working before bu...
Using an STM32H723 I started with a non interrupt USART connection onto a wifi module.I set up the connection on UART3 implementing nothing more than that and using these instructions int len = sprintf(tx_buff,"AT+GMR\r\n");HAL_UART_Transmit(&huart3...
This should be simple, but I can't find documentation. I am running an STM32L4P5 at max clock speed (120 MHz), and I have moved all code to SRAM so it is running with zero wait states. I have an extensive calculation to do using the FPU -- I am ...
