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...
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...
