I hope we can keep on going. A good start is half the success. All we do today is to do better in microcontroller programming. Before talking about today's topic, let me tell you about some of my previous experiences. In the beginning of contact with the C language program

For power-on reset, software SOC reset and watchdog SOC Reset:GPIO_STRAP_REGIf you require UART or SDIO download mode, check the register. In this case, configure UART or SDIO and wait for the code to be downloaded. Otherwise, continue to start, as if due to software CPU reset. For software CPU reset and watchdog
