Я использую таймер для черчения и хранения одновременно.Когда я отображаю 2 значения, нет потери данных с последовательного порта (60 строк в минуту, мое устройство = 1 Гц).Но когда я пытаюсь построить более двух значений, это повредит данные (~ 40 строк в минуту).
1.Мне попробовать thread или queue вместо wx.Timer?
2.Почему wx.Timer повреждает мои данные?или в чем проблема?
3. Должен ли я использовать последовательный порт func.внутри wx.Timer ??
Где я делаю что-то не так и что?Мне нужна ваша помощь.Любая помощь будет оценена.
