    • 回复: T113 I2S 音频输出至 Lontium 芯片 / T113 I2S Audio Output to Lontium chip

      @whycanservice2 感谢您的回复。这似乎已经修复了错误。我不再收到错误，我可以使用“cat /sys/kernel/debug/pinctrl/pio/pinmux-pins”来查看引脚是否已分配给 I2S。

      但是我仍然无法通过 I2S 播放音频。我正在使用 tplayerdemo 播放带音频的视频。我会继续调查，但有什么想法吗？

      此外，是否有资源或文档可以让我稍后自己查找此信息？我查看了 Tina SDK 手册，但似乎找不到此信息。

      非常感谢您的帮助！

    • 回复: T113 Tina上面增加配置了gstreamer之后，编译会报下面的错误

      我找到了解决方案：

      在 gst1-omx Makefile（位于 t113-sdk/package/multimedia/gst1-omx）中，您需要将 t113 添加到 TARGET_BOARD_PLATFORM

      之前：
      ifeq ($(TARGET_BOARD_PLATFORM),$(filter $(TARGET_BOARD_PLATFORM), r16 r311 r58 r40 g102 r11 r7 r528))
      OMX_COMPILE_TOOL_CHAIN = arm-openwrt-linux
      endif

      之后：
      ifeq ($(TARGET_BOARD_PLATFORM),$(filter $(TARGET_BOARD_PLATFORM), r16 r311 r58 r40 g102 r11 r7 r528 t113))
      OMX_COMPILE_TOOL_CHAIN = arm-openwrt-linux
      endif

    • [付费] T113-S3 视频播放系统

      我们正在寻求开发一款 1080p 60hz 视频/媒体播放设备。我们需要一个视频播放系统，允许在播放另一个视频时以不可见的方式预加载一个视频，然后在这些视频之间无缝切换。

      我们还需要视频无缝循环。

      应用程序的大部分高级逻辑已经实现。然而，我们在视频播放的上述方面遇到了困难。

      使用 Tina Linux SDK，我尝试改造 tplayer 库以实现上述目标，但没有成功。

      我们愿意聘请某人开发或修改 T113-S3 芯片上的视频播放系统。

      谢谢，
      Daz

    • 回复: T113: Python 3.5 Package Cross-Compile

      @zoenggit Many thanks for your suggestion and link. Using it, I was able to figure out how to edit the makefile to get spidev to correct build.

      I created folder tina-d1-h/package/lang/python3-spidev, and in it I create Makefile. Below is the Makefile:

    • 回复: T113: Python 3.5 Package Cross-Compile

      @zoenggit appreciate the response and link. I'm using the Tina Linux 2.0 SDK, which is based on OpenWRT. I'm using the Tina Linux build downloaded from this forum.

      I believe the packaging system is a bit different to buildroot. I did attempt to include the spidev package in the build system, but couldn't figure how to make it work.

      Do you have any experience or advice in how to get it to work?

    • T113: Python 3.5 Package Cross-Compile

      大家好，
      在 Tina Linux 中，我尝试安装适用于 Python 3.5 的 spidev Python 包。它不包含在 SDK make menuconfig 中
      我一直在尝试交叉编译，但到目前为止还没有成功。
      有人可以提供有关如何安装 Python 包的建议或说明吗？
      谢谢！

      Hi all,
      In Tina Linux, I'm trying to install the spidev Python package for Python 3.5. It's not included in the SDK make menuconfig
      I've been trying to cross compile, but so far I've had no success.
      Can anyone provide advice or instructions on how to install a Python package.
      Thank you!

      谢谢你们的帮助。附件中的文档和链接非常有用。

      我用示波器检查了引脚，可以看到 I2S 正在输出。在咨询了 Lontium 后，我终于能够将正确的 I2S 格式输入芯片中。

    • 回复: T113 I2S 音频输出至 Lontium 芯片 / T113 I2S Audio Output to Lontium chip

      @whycanservice2 感谢您的回复。这似乎已经修复了错误。我不再收到错误，我可以使用“cat /sys/kernel/debug/pinctrl/pio/pinmux-pins”来查看引脚是否已分配给 I2S。

      但是我仍然无法通过 I2S 播放音频。我正在使用 tplayerdemo 播放带音频的视频。我会继续调查，但有什么想法吗？

      此外，是否有资源或文档可以让我稍后自己查找此信息？我查看了 Tina SDK 手册，但似乎找不到此信息。

      非常感谢您的帮助！

    • T113 I2S 音频输出至 Lontium 芯片 / T113 I2S Audio Output to Lontium chip

      嗨。我正在尝试配置我的 T113，以将 I2S 音频输出到 Lontium LT9611UXC MIPI 到 HDMI 芯片。我已将我的 DTS 配置为输出 I2S。但是查看 dmesg 我发现我的 DOUT 引脚未正确初始化：

      [    1.881261] sun8iw20-pinctrl pio: unsupported function i2s2 on pin PB4

      有什么帮助或想法吗？最后是我的 dts：

      Hi. I'm trying to configure my T113 to output I2S audio to a Lontium LT9611UXC MIPI to HDMI chip. I've configured my DTS to output I2S. However looking at dmesg I see that my DOUT pin isn't properly initialised:

      [    1.881261] sun8iw20-pinctrl pio: unsupported function i2s2 on pin PB4

    • T113: GPIO 输入上拉 (Input pull-up)

      我想将 GPIO 输入设置为上拉。我见过各种驱动程序将 GPIO 配置为 LED 或按键输入：
      https://bbs.aw-ol.com/topic/1421/mq_pro-tina-gpio驱动
      https://whycan.com/t_6900.html#p66192

      但是我只想将引脚设置为 GPIO 输入上拉，然后在我的应用程序中通过以下方式访问：/sys/class/gpio

      有什么建议吗？非常感谢。

    • [付费] T113-S3 视频播放系统

      我们正在寻求开发一款 1080p 60hz 视频/媒体播放设备。我们需要一个视频播放系统，允许在播放另一个视频时以不可见的方式预加载一个视频，然后在这些视频之间无缝切换。

      我们还需要视频无缝循环。

      应用程序的大部分高级逻辑已经实现。然而，我们在视频播放的上述方面遇到了困难。

      使用 Tina Linux SDK，我尝试改造 tplayer 库以实现上述目标，但没有成功。

      我们愿意聘请某人开发或修改 T113-S3 芯片上的视频播放系统。

      谢谢，
      Daz
