Normally you will kick the watchdog after performing a number of tests on the entire system, for example, are the correct number of tasks running, has each task executed the expected number of times, have any tasks failed to execute since. After reset, LED will light for a half-second. Peripherals have been connected on this bus to increase peripheral speed: Motor control The STM32 Performance line embeds timers and ADC features that are perfectly suited to three-phase brushless motor control. A watchdog is a generic term for a type of circuit that monitors another circuit. If you fail to refresh the watchdog …. 1 Simple definition of a Microcontroller ↑. This interface is defined by the SDA and SCK pins. Change the request to USART2_TX, and you can leave the rest of the settings at their defaults. STM32F103 provides an embedded window watchdog timer to supervise the code execution. Let's take an example if I want to set the timeout to 20ms. The below code is working fine until IWDG is resetting the MCU from STOP mode. And I am talking about the LL interface, the HAL one is a maze. Start a new project in STM32CubeIDE with C. Ở đây ta chỉ sử dụng ADC1 chennel 0 (PA0).
