[提问]小安派 AiPi-Eyes-Rx TF卡槽

[i=s] 本帖最后由 WT_0213 于 2024-1-19 15:00 编辑 [/i]<br /> <br /> 发现小安派AiPi-Eyes-R1和AiPi-Eyes-R2都有预留TF卡槽的位置，未焊接卡槽。 如果 AiPi-Eyes-Rx 补焊 TF卡槽，是否可以直接使用。与哪些硬件冲突呢。 想要在TF卡里面存一些图片或者音视频文件。是否可行。 如果可行的话，希望官方大佬能出个相关的教程，自带的存储有限存不了太多东西。 😄 sdcard sdh_sdcard.h ``` /** * @file sdh_sdcard.h * @brief * * Copyright (c) 2021 Bouffalolab team * * Licensed to the Apache Software Foundation (ASF) under one or more * contributor license agreements.

我来问问小泽

好的，辛苦了

SD卡可以看D200的demo，里面有用到文件系统，SD卡读写这些。占的脚位是SDIO那几个脚位，基本就是CAM那些了。

大佬，R1和R2直接焊接卡槽就可以使用吗。咱们调试的时候有在 AiPi-Eyes-R1或AiPi-Eyes-R2上面用过 TF卡槽吗。 最好是有一些例子。目前找到了，sdcard 相关的h头文件和C文件。全局搜索了以下，好像没有找到引用。 懵懵的。如果不太占用咱们时间的话，辛苦咱们大概发一下 相关引用代码。比我这里梳理可能稍微快捷一些。我这里也看一下。 感谢。
