输入在 pygame 和 adafruit-touchscreen 中转移 [英] Input shifted in pygame and adafruit-touchscreen

问题描述

我在使用以下硬件输入 pygame 时遇到问题:

• 树莓派 1 B
• Adafruit 5" 触摸屏通过 HDMI 连接并通过 USB 触摸输入

触摸屏根据 adafruit 网站(将/boot/config.txt 中的分辨率修正为 800x480px).

在 raspbian 的用户界面中一切正常.但是一旦我启动我的 pygame 应用程序，我就会遇到奇怪的行为.该应用程序在普通 PC 上运行良好.视频分辨率似乎正确，但其中一个触摸屏略高.

我通过以下方式调用 pygame:

self._display_surf = pygame.display.set_mode([800,480], pygame.FULLSCREEN)self._display_surf.fill(COLOR_BG)pygame.display.update()

我面临的问题是，如果我滑过屏幕，鼠标指针会超过"我.我制作了一个小视频以便更好地理解.>

我已经用

打印了一个列表

pygame.display.list_modes(16)

我以

结尾

[(1600, 1200), (1280, 1024), (1024, 1024), (1280, 960), (1152, 864), (1024, 768), (800, 600), (768, 576), (800, 480), (640, 480)]

但我不知道这些来自哪里.我无法为触摸输入和屏幕设置不同的分辨率，对吗?

解决方案

该问题是通过 ssh 调用程序产生的.在本地shell中调用程序解决了这个问题.

I am facing an issue with the input into pygame using the following hardware:

• Raspberry Pi 1 B
• Adafruit 5" Touchscreen connected via HDMI and Touch Input via USB

the Touchscreen is set up according to the howto on the adafruit website (fixing resolution in /boot/config.txt to 800x480px).

It is all working perfect in the userinterface in raspbian. But as soon as i start my pygame application, I experience strange behaviour. The application is working perfectly well on a normal pc. It seems like the video resolution is correct, but one of the touchscreen is slightly higher.

I am calling pygame with:

self._display_surf = pygame.display.set_mode([800,480], pygame.FULLSCREEN)
self._display_surf.fill(COLOR_BG)
pygame.display.update()

The issue I am facing is that if I slide over the screen, the mouse pointer is "overtaking" me. I made a little video for better understanding.

I already printed a list with

pygame.display.list_modes(16)

where I end with

[(1600, 1200), (1280, 1024), (1024, 1024), (1280, 960), (1152, 864), (1024, 768), (800, 600), (768, 576), (800, 480), (640, 480)] 

But I have no idea where these come from. I cannot set different resolutions for touch input and screen, am I right?

解决方案

The issue was produced by calling the program via ssh. Calling the program in a local shell solved the problem.
