Why is the digital pen still hanging on the board?

Generally, there are the following situations:

1. driver problem can be solved by reloading the driver;

2. Because it has been used for a long time, there may be foreign objects stuck in the nib, resulting in the problem of always feeling oppressive, which can be solved by plugging and unplugging the nib again;

3. If the first two methods can't solve the problem, there may be something wrong with the hardware of the pressure-sensitive pen. There is always a sense of oppression when the pen is broken, so it needs to be repaired at the maintenance point.
