我们先来看一下“Pinout&Configuration”标签页,在该标签页的左边一栏,所有的外设被分成:系统内核,模拟,定时器,通信,多媒体,安全和计算几个组进行显示。比如,点开通信(connectivity)这个组,就可以串口,I2C这些外设。 freeRTOS, FATFS等协议栈在Middleware分组下。右边默认显示的一个MCU的引脚分配图,在左边栏使能了某...
Fairly regularly (around ~1.5 hours, on a 100Hz interrupt, with other transactions alongside), I find that the system has locked up - some interrupts are still being serviced (e.g: I2C, CAN), but the application flow has entirely halted...

To make the best decision on the STM32 microcontroller selection, there are several factors to consider, mainly the architecture to select, the memory and power requirements, the peripherals to support such as the communication peripherals: USB, I2C, SPI, UART and the cost to review. The select...
And if the driver for example needs functions from the LL I2C C-files, the driver Kconfig file should include the following entry select USE_STM32_LL_I2C Use STM32Cube in your application: It may happen that you want to access STM32Cube APIs in your application, either because it is not...
MDK的工程项目中,添加后的效果如下: ThreadX/Ports分组文件位置 文件tx_initialize_low_level.s在路径ThreadX\ports\cortex_m4\ac5\example_build。 其它文件在路径Thread\ports\cortex_m4ac5\src。 ThreadX/Source分组文件位置 全部在路径ThreadX\common\src,所有文件全部进来 推荐使用下面的方法添加,...
