Мой текущий GUI - показать отслеживание цели от процессора TI до P C через UART. Иногда происходит сбой GUI из-за производительности UART. Но каждый раз, когда я хочу сбросить GUI, я также должен сбросить свое устройство TI. Поэтому я хочу изменить код python, чтобы только заново открыть GUI, ввести COM-порт без необходимости сбрасывать устройство при сбое GUI.
В настоящее время каждый раз, когда происходит сбой GUI, хотя я снова открыл GUI, но не сбросил устройство (выключение и включение), я не могу продолжить отслеживание.
Я поставил python код для GUI ниже. В этой программе GUI python у нас есть 2 пробела и кнопка для входа в COM-порт UART, 2 кнопки для выбора и отправки конфигурации на устройство. Затем он может начать отслеживание.
Я собираюсь изменить часть sendCfg (self), но все еще не уверен, как заставить это работать в качестве моей цели из-за моего отсутствия опыта в Python & GUI дизайне. Пожалуйста, помогите мне с примером кода для этой задачи.
